Question

Which is not a feature of dinoflagellates?

Answer 1

Dinoflagellates are mostly marine and photosynthetic in nature. The cell wall has stiff cellulose plates on the outer surface. Very often, red dinoflagellates (Example: Gonyaulax) undergo such rapid multiplication that they make the sea appear red. This phenomenon is known as a red tide. Toxins released by Gonyaulax large numbers may even kill other marine animals such as fishes.
