Phytoplankton in Marine Biodiversity
Phytoplankton are microscopic organisms that play a crucial role in marine ecosystems as they form the base of the food chain. They are responsible for producing a significant portion of the Earth's oxygen through photosynthesis.
Identifying Phytoplankton
- Diatoms: Diatoms are a type of phytoplankton that are characterized by their intricate silica shells. They are one of the most common types of phytoplankton found in marine environments.
- Dinoflagellates: Dinoflagellates are another type of phytoplankton that have two flagella for movement. They are known for their ability to produce bioluminescence in the ocean.
- Coccolithophores: Coccolithophores are a group of phytoplankton that have calcium carbonate plates covering their cells. They are important contributors to the global carbon cycle.
Therefore, in the context of marine biodiversity, diatoms, dinoflagellates, and coccolithophores are all examples of phytoplankton.
Hence, the correct answer is option 'A' - 1, 2 and 4 only.

In the context of marine biodiversity, whichof the following are phyto...
- Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.
- Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
- The two main classes of phytoplankton are dinoflagellates and diatoms. Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells. Diatoms also have shells, but they are made of a different substance and their structure is rigid and made of interlocking parts.
- Diatoms do not rely on flagella to move through the water and instead rely on ocean currents to travel through the water.
- Coccolithophores are also a group of phytoplankton that live in large numbers throughout the upper layers of the ocean. Coccolithophores surround themselves with a microscopic plating made of limestone (calcite).
- Crustaceans include all the animals of the phylum Arthropoda. Crustaceans are a very diverse group of invertebrate animals that includes active animals such as crabs, lobsters, shrimp, krill, copepods, amphipods, and more sessile creatures like barnacles. Arthropoda is the largest phylum of Animal Kingdom.
- Foraminifera represents an ancient species of zooplankton that live mostly in sediment but also in the water column. They belong to the kingdom Protista.
- Phytoplankton varies seasonally in amount, increasing in spring and fall with favourable light, temperature, and minerals.
- Hence option (a) is the correct answer.
