What type of plankton is Asterionella?
Asterionella formosa is a common diatom in the plankton of lakes and slow moving rivers.
Where is Asterionella found?
Asterionella is a genus of pennate freshwater diatoms. They are frequently found in star-shaped colonies of individuals.
What is phytoplankton?
Phytoplankton are microscopic marine algae. In a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow.
What are the types of Phytoplanktons?
Phytoplankton are the single-celled organisms that play an important role in the aquatic food web, and different types include green algae, cyanobacteria, coccolithophores and dinoflagellates.
What phytoplankton means?
What is the function of diatoms?
Since diatoms are able to photosynthesize, they convert dissolved carbon dioxide in the water into oxygen. They are a primary food source for higher organisms in the food chain, such as invertebrates and small fish. Diatoms can also play important roles in the energy and nutrient cycles of water resources.
What do diatoms produce?
Diatoms are considered the largest primary producers of oxygen on our planet. It is estimated that through photosynthesis, diatoms produce between 20% and 40% of the oxygen we breathe. During photosynthesis diatoms use energy from light to convert water and carbon dioxide into sugars for food.
Why are phytoplankton important to humans?
Through photosynthesis, phytoplankton use sunlight, nutrients, carbon dioxide, and water to produce oxygen and nutrients for other organisms. With 71% of the Earth covered by the ocean, phytoplankton are responsible for producing up to 50% of the oxygen we breathe.
Is phytoplankton good for humans?
Phytoplankton is a good source of omega 3s, and omega 3s are known to have numerous health benefits to humans, including cardiovascular health. If you find a phytoplankton source that seems safe and responsible, you might reasonably consider it to be healthful.
What is phytoplankton made up of?
Phytoplankton. Phytoplankton is made of very tiny–usually one-celled–plants. Since plants make their own food and release oxygen as a byproduct, all the other living things in the ocean depend on them directly or indirectly for food or oxygen.
What is special about diatoms?
They are the only organism on the planet with cell walls composed of transparent, opaline silica. Diatom cell walls are ornamented by intricate and striking patterns of silica.

Is Asterionella formosa a planktonic diatoms?
Asterionella formosa is common in mesotrophic and eutrophic lakes globally and is one of the most common planktonic diatoms in these lakes in the northern hemisphere.
