What Plants are in the Marine Biome?

The marine biome, also known as the marine ecosystem, is a complex and diverse environment that spans the world’s oceans. It is home to an incredible array of plant life, from the tiniest microorganisms to giant kelp forests. In this article, we’ll explore the types of plants that can be found in the marine biome.

Phytoplankton

Phytoplankton are microscopic plants that drift in the water column, using sunlight to convert carbon dioxide and water into glucose and oxygen. These tiny organisms are the base of the marine food chain, providing sustenance for zooplankton, fish, and other marine animals.

Types of Phytoplankton:
• Diatoms: These are the most common type of phytoplankton, with intricate frustules made of silica. They are a vital part of the ocean’s nutrient cycle.
• Blue-green algae: These algae are actually cyanobacteria, but are often referred to as "algae". They play a critical role in fixing nitrogen from the atmosphere into the water.
• Green algae: These are larger and more complex than diatoms, with a wide range of shapes and sizes.
• Flagellated algae: These algae are characterized by their flagellated cells, which are capable of movement.

**Seagrasses and Seaweads**

Seagrasses and seaweeds are plants that grow anchored to the seafloor or floats in the water column. They provide a habitat for a wide range of marine animals, from fish and invertebrates to mangrove crabs and other crustaceans.

Seagrasses:
• Posidonia oceanica: This type of seagrass is found in the Mediterranean and is considered an endangered species.
• Zostera marina: Commonly known as eelgrass, this species is found in temperate waters around the world.
• Thalassia testudinum: This type of seagrass is found in warm, tropical waters and is an important habitat for manatees.

Seaweeds:
• Kelp: A type of brown algae that can grow up to 100 feet tall.
• Sargassum: A type of brown algae that floats in the water column.
• Dulse: A type of red algae that is edible and is often used as a food source for livestock.

**Corals**

Corals are tiny animals that are found in tropical waters around the world. They have a symbiotic relationship with algae, which live inside their tissues and provide nutrients through photosynthesis.

Types of Corals:
• Hard corals: These corals have a hard, calcified skeleton that provides protection for the animal inside.
• Soft corals: These corals are actually a type of alcyonacea, but are often referred to as "soft corals". They do not have a hard skeleton.
• Stony corals: These corals have a hard, stony skeleton that is made up of the coral animal’s body.
• Gorgonians: These corals are actually a type of soft coral, but have a more rigid skeleton than other soft corals.

Other Marine Plants

• Mangroves: These are trees or shrubs that grow in coastal areas and provide habitat for a wide range of marine animals.
• Sea fans: These are soft corals that resemble fans or feather duster worms.
• Mermaid’s purses: These are actually the cases of shark and ray embryos, but are often mistaken for plants.
• Kelp forests: These are dense forests of seaweed that provide habitat for fish, invertebrates, and other marine animals.

Conclusion

The marine biome is a vast and diverse environment that is home to a wide range of plants. From the tiny phytoplankton to the giant kelp forests, each type of plant plays a critical role in the marine ecosystem. Understanding and appreciating these plants is essential for the conservation of the marine biome and all the animals that depend on it.
