A) Trichodesmium erythrium
B) Physarium
C) Dinoflagellates
D) Diatoms and members of red algae
Correct Answer: A
Solution :
Trichodesmium erythrueum is a blue-green algae, in which the red pigment predominates. This species flourishes in red sea and is responsible for the red colour of its water. Dinoflagellates consist of golden brown photosynthetic protists. They are called so due to presence of 2 flagella. Some of them produce red tide (eg, Gonyaulax, Gymnodinuim). Diatoms are unicellular golden brown autotrophic protists. Siliceous cells of diatoms pile up to form diatomaceous earth or diatomite.You need to login to perform this action.
