Practice question
Question
A marine photosynthetic protist possesses stiff cellulose plates and two flagella, one longitudinal and one transverse. What may result if red-coloured members multiply rapidly?
Explanation
These features identify a dinoflagellate. Red dinoflagellates such as Gonyaulax may multiply so rapidly that the sea appears red. Toxins released by such large populations may kill marine animals, including fishes.
