Top 40 Ocean Plants – Existences (#Images)
Number of ocean plants is absolutely greater than ocean animals. As in the bottom of nutrient cycling and food chain, ocean plants have to feed food demand to creatures in the higher level of the chain. Like ocean animals, humans’ knowledge on ocean plants is rather limited. We conclude that human as a part of the earth’s ecosystem do not yet know the importance of other roles. This article give us important lesson on the ocean life particularly ocean plants.
We see further in this article that adverse effects occur to ocean particularly ocean plants. These come from human activities include among others pollution, climate change, global warming, sea transportation, exploration and exploitation inside ocean ecosystem including coastal regions throughout the world. We are afraid the adverse effects of human activities will hit humans themselves particularly the existence of human beings on the earth.

- Phytoplankton (Phytoplankton)
Phytoplankton are classified into Kingdom Monera. They are from the plankton community with auto-tropic or self feeding capability of producing energy from photosynthesis and chemo synthesis.
Where sunlight penetrates ocean waters, phytoplankton flow with water current. In the 200-meter depth of ocean water, phytoplankton can be found. These consist of three groups. Such as golden-brown algae, green algae and blue-green algae. Biologists gauge whether ocean water is polluted or not depend on phytoplankton’s health and abundance.
The amount rises and decreases and it depends on friendly light, temperature and minerals. Ocean pollution, climate change and global warming can terminate the life of phytoplankton. The reproduction system is through fission.
- Green Algae (Chlorophyta)
Green algae have Phylum Chlorophyta and Class Chlorophyceae. There are many species under Phylum Chlorophyta. It is mostly found in cell colonies. It is single-celled and microscopic plant. In its evolution, green algae gave rise to the first land plants. The habitat is mostly aquatic plant in freshwater and marine.
Biologists consider green algae has important position in the food chain. Thus, the primary producers give living organism usable energy by converting sunlight and inorganic chemicals. Green algae become food supply for zooplankton, for example.
Despite some grow on soil, trees or rock, those are not included Chlorophyta or chlorophytes but Trebouxiophyceae. The reproduction may be in a kind of fission (splitting), budding, fragmentation or by zoospores (motile spores). Humans take benefits from green algae, i.e. cancer drugs, aquarium and food supplement.
- Golden-brown Algae (Chrysophyceae)
Golden-brown algae has Phylum Ochrophyta and species Chrysophyceae. These are single-celled algae with their habitat in salt and freshwater.
Then, the cell walls dominantly have pectin plus silica, and these make the plant rather rigid. Golden-grown algae store carbohydrate and large oil droplet as their energy.
When Golden-brown algae swim they get aids from their flagella. Golden-grown algae have photsynthetic pigments, namely chlorophylls A and C.
On the other hand, the plants are important in ocean waters for its productivity and biomass building particularly the micro fraction of the phytoplankton, namely nanoplaknton with the diameter of cells less than 0.05 mm. When dying, the shells of golden-brown algae stimulate sediment building on the sea and it is beneficial for filtration in liquid purification system.
- Blue-green Algae (Cyanobacteria)
Blue-green algae has Phylum Bacteria and species Cyanobacteria. Blue-green algae obtain energy from photosynthesis and they are the only prokaryotic being able to produce oxygen from photosynthesis. Forbidding drinking raw water is suggested because the blue-green algae change the taste of drinking water when they undergo bloom.
Blue-green algae is not “primary producers” for higher organism and on the contrary, these have adverse effect to other aquatic organisms. For example, the breakdown of blue-green algae bloom requires oxygen demand, and deplete oxygen for aquatic organism.
Blue-green algae cause some symptoms, such as stomach cramps, diarrhea, vomiting, headache, fever, muscle weakness, difficulty breathing.
- Red Algae (Rhodophyta)
Red algae has Phylum Rhodophyta, Class Florideophyceae. Red algae are mostly marine algae. Total number of red algae reaches 4,000 species and mostly in tropical waters.
The size is diverse from microscopic to macroscopic. It is able to do photosyntehsis with their pigment. Namely chlorophylls A and D Red color from the algae comes from pigments called phycoerythrins.
When absorbing blue light in the pigments, red algae can live over 500 feet in the depth. The algae store energy in a form of lolysaccharide called floridean startch.

- Brown Algae (Phaeophyceae)
Brown algae has Division Chromophyta, Phylum Phaeophyta and Class Phaeophycea. These are multicellular algae and a group of photosynthetic protists. There are about 1,500 species of Brown algae.
The algae are common in cold waters along continental coastline particularly in Northern Hemisphere. The algae are mostly found on rocky ocean shores. Their species lived in freshwater are rare. The algae multiply by asexual and sexual reproduction. Humans have benefit from brown algae, namely Algin.
Algin is a clloidal gel that has the function of stabilizer in ice cream and baking industry or eaten as a vegetable, i.e. Laminaria in some East Asian countries. Sargachromanol G in brown algae has anti-inflammatory characteristic.
- Killer Algae (Caulerpa taxifolla)
Killer algae have Kingdom Viridiplantae, Phylum Chlorophyta and Genus Caulerpa. It is found in tropical waters of Indian Ocean, Atlantic and Pacific Oceans. Why the algae are found in Mediterranean Sea and Southern California.
The reproduction system is by vegetative way. The algae can grow around 1 cm per day. They can form new stems and fronds. They have negative effects to environment. Their fast growth replaces the host algae and sea-grasses.
Moreover, the herbivores that feed the host algae replaced by Killer algae can be killed because the algae are highly toxic. The algae can be controlled through the coverage of Killer algae with tarps and the pumping of chlorine bleach under the coverage. However, the algae are adaptable to temperate condition. They are found in the depth of 3-30 meters.
- Yellow green Algae (Xanthophyta)
Yellow-green algae has Domain Eukaryota, Phylum Ochrophyta and Class Xanthophyceae. Being Eukaryotic cell in single celled or colony, cellulose, pectin and silica make of their cell walls. The algae have two flagella or more for their moving. Their energy is stored in a form of carbohydrates. The pigments carotenoids and xanthrophyll make of the yellow-green color.
Their sexual reproduction is a kind of Isogamous, Anisogamous or Oogamous. The life span is haplontic. The algae cover Yellow Sea for almost 200 square miles.
On the other hand, they are not poisonous but deplete oxygen in the sea water. The algae threatens the life of marine ecosystem. Yellow-green algae, diatoms, flagellates and coccolithophorides are important phytoplankton in the earth, and they have a great role of organic production.
- Diatoms (Phylum Bacillariophyta)
Diatoms include Kingdom Stramenopila and Phylum. The habitats are in terrestrial, marine and freshwater. The very small cell walls of Diatoms is glass like called frustules.
These are composed of siliica. The frustules deposits can be mined to provide diatomaceous earth for paints, cement, fertilizers, toothpaste, polishes and cleaners.
Diatomaceous can kill snails and slugs. The reproduction system is through the form of new valve (cell) walls inside the parent cells. and the new ones will be smaller than their parent.
Humans use diatoms as environmental assessment and monitoring for their tolerance to some environmental variables, such as nutrient concentration, suspended sediments, flow regime, elevation and human disturbances. Scientits will know species preferences from the interpretation of the diatom species from the past.

- Dinoflagellates (Dinoflagellata)
Dinoflagellates has Kingdom Alveolata and Phylum Dinoflagellata. The algae can movie with their two flagella. The algae include protozoa but their cell walls of many plates like armor make them autotrophic. The algae are called sea ghost because they can produce light over sea surface.
The habitat is mostly marine plankton but common in freshwater. Temperature, salinity or depth influence their population. Dinoflagellates can live in low oxygen. Some species dinoflagellates are important in the life of coral reefs for its endosymbionts with marine animals. The reproduction system involves asexual with binary fission (Desmoschisis or Eleuteroschisis).
Despite some species dinoflagellates has sexual reproduction. Dinoflagellates can produce dinotoxins. It is dangerous for fish and humans when they eat shellfish, the filter feeders with full of the toxins. For hobbyist’s aquarium, however, dinoflagellates are parasitic and predatory as well.
- Giant Kelp (Macrocystis pyrifera)
Giant kelp has Kingdom Protista, Phylum Heterokontophyta, Class Phaeophyceae. It is found in Indian, Atlantic and Pacific ocean. It can survive in cooler waters under 21 degree Celsius. It is the largest seaweed in the world. It can grow up to 21 feet or 30 meters.
The kelp forest is large and dense, and it is beneficial for marine species. Under Kingdom Protista, it is an organism with single cell, and it is the largest protist in the ocean waters. It gets nutrition from the ocean water surrounding it despite Hold-fast like a structure of Giant kelp attach it to ocean floor.
Meanwhile, the dense, large forest becomes an important ecosystem in temperate coastal areas. Ocean animals live in Giant kelp forest, such as lobsters, squid and other invertebrates. Humans produce food and chemical products from Giant kelp.
- Bull Kelp (Nereocystis leutkeana)
Bull kelp has Kingdom Chromalveolata, Phylum Heterokontophyta and class Phaeophyceae. It is an annual seaweed because it is able to grow fast just in one summer. It can grow up 15 inches or 25 cm in one day or 115 feet or 15 meters in size.
The habitats are Pacific coast from Alaska to southern California. It produces spore patches or sori. Due to its heavy it falls into ocean floor. It can establish bull kelp forest. It is dying by winter. When life it becomes protective shelter for fishes and many invertebrates, like crabs, and food source on ocean floor.
Then, when die it is a food source and beach shelter for some ocean animals, like scavenging amphipods. It can create kelp beds for a resting area of ocean animals, such as otters, waterfowl. Moreover, it reduces erosion on the beach.
- Irish Moss (Chondrus crispus)
Irish moss has Kingdom Protista, Phylum Rhodophyta and Class Rhodophyceae. It grows in Atlantic coast particularly in coastline water of North America and Europe. It is also called read seaweed with flattened blades. It can grows up to 2-6 inches in tall and 4 inches in wide.
Despite it is deep purplish red color, Irish moss may have white, brown or green color. It is mostly found in inter-tidal zone and below the rock-weeds and above the kelp. It can grow well in dry condition and high humidity.
In ecosystem, it grow from seeds. The seed germinates around 7-28 days. It is easy to care. Humans use Irish mosh as food ingredient and dairy products. People in New England use it as an extract called Narraganset.
- Neptune grass (Poseidonia oceanica)
Neptune grass has Kingdom Plantae, Phylum Tracheophyta, Family Posidoniaceae. It is a plant with marine flower, and has endemic in the Mediterranean Sea. It’s favorite zone in sheltered coastal waters. As a primary producer and stabilizer in the seabed, it becomes habitat for other marine organisms.
In the habitat, it maintains the ecosystems. The plant is relatively slowly rapid growth. When the population are rapidly decreasing due to human activities, such as coastal construction, fish farming, climate change, and it does not recover immediately.
The reproduction system is that male and female flowers produce in the same inflorescence. The habitat extends in the western Mediterranean from France, Italy to the Andalusian region and Greece, Montenegrin region, Malta, Turkey and Algeria.
- Sea Lettuce (Ulva lactuca)
Sea lettuce has Phylum Chlorophyta and Family Ulvaceae. It is a algae or a green seaweed throughout the world. Sheltered rocks and shores along inter-tidal coastline water are its favorite habitat. It can grow in the mouths of rivers, run-off pipes and streams. However, when growing around run-off pipes, product from Ulva lactuca is not recommended. Sea lettuce is commonly found along the Irish Shoreline. In its growth it is attached to rocks. It grows up to 45 cm in the length and 30 cm across. Humans use it for cooking ingredients and herbal, such as the treatment of burn and gout, source of iodine and astringet.

Plantae, Phylum Tracheophyta and Family Zosteraceae. Eelgras is a blooming underwater grass. It spread by rhizomes or roots. The reproduction system is by meadows. It grows in spring and summer. When dying it occurs in the fall and winter.
Eelgrass meadows provides food and shelter for sea animals, like Salmon, crab. The habitat is muddy, sandy bottoms of ocean floor, and it lives on shallow sub-tidal wave. It spreads in northern latitudes, i.e. north, Atlantic and north Pacific ocean. The destructed habitat will threaten the life of fish, Salmon, shellfish and other ocean animals.
When stabil, it maintains shorelines from erosion. Blade of Eelgrass’s leaves provide food for diatoms, bacteria and detrius. When dying Eelgrass’s leaves feed bacteria and fungi breaking them into tiny bits for nutrients in nearshore food chain.
- Zooxanthellae (Symbiodinium sp)
Zooxanthellae have Phylum Dinoflagellate, Genus Symbiodinium and Genus Amphidinium. Zooxanthellae lives on corals. It builds coral reef. Between coral and algae there is mutualistic relationship. The coral gives zooxanthellae a protected environment. Then, it produces oxygen and the coral can remove wastes. It contributes glucose, glycerol and amino acids to the coral.
All of the compounds are the products of photosynthesis. Zooxanthellae is an algae and on the coral it gives pigmentation. Zooxanthellae are an algae with single cell. With its mutual relationship to coral, it also has symbiosis with various marine invertebrates, such as jellyfish.
Meanwhile, the algae does not survive with temperature changes whether it is rise or decline because a coral bleaching event can occur.

The distribution is similar to coral reefs, and it has 35 species and 60 species of mangrove associates or more. It differs from other mangroves from its prop roots and fruits. The reproduction is through propagules. Red mangrove can grow normally if it meets hyrological factors and nutrient supply plus temperature.
Mangrove crab, the mangrove land crab, coffee bean snail and the ladder horn snail are the main consumer of red mangroves. The plant has two common enemies, i.e. habitat destruction and ocean pollution.
- Coccolithophorides (Coccosphaerales)
Coccolithophores are marine plants with one cell lived in the upper layers of the ocean in great numbers. Limestone or calcile covers the microscopic plating. Their scales called coccoliths and surrounded by at least 30 scales have hubcap-like form. The coccoliths dump around 1.4 billion kilograms of calcite per year. The algae becomes the biggest calcite producers in the earth’s oceans. The algae lives on ocean surface with scarce nutrient water in temperate condition. So, they do not compete with other algae to live. Moreover, they are source of nutrition in water with rare nutrition Coccolithophores live in Indian, Atlantic and Pacific Ocean from Australia, Iceland to Bering Sea. Concerning global climate, coccolithophores have role by increasing the oceans’ albedo, i.e. the fraction of sunlight on object reflects. It occurs when the algae blooms. They contributes greenhouse gas as well.
Other Ocean Plants
For the next ten ocean plants we discuss mangroves by ecoregions. Ecoregion is an area with distinct ecology and geography. It is smaller than an bioregion. However, bioregion is smaller than an ecozone. Ecozone itself is lesser or greater than ecosystem. However, ecoregion has a specific characteristics of natural communities and species in large area of land or water. The specific characteristics relate to the biodiversity of flora, fauna and ecosystem, and it differs from other ecoregions. There are five ecoregions of mangroves, i.e. Afrotropic, Australasian, Indomalayan, Neotropic. In the following points we select some mangroves from these ecoregions.

Finally, from the above description we see there are a bulk of ocean plants. They are important in the food chain and nutrient cycling. However, human activities have changed the condition of some ocean waters from deep water to coastal line. Water pollution, the expansion of agriculture, overfishing, global warming and climate change as well as low knowlege on the function of ocean plants in our ecosystem make various ocean plants in danger. Further actions should be carried out if we want better future better life.
