Which of the Following Characteristics Do Dinoflagellates Exhibit

Question

Which of the following characteristics do dinoflagellates exhibit?
A) They possess two flagella.
B) They are all autotrophic.
C) They lack mitochondria.
D) They include species that cause malaria.

Accepted Answer

Dinoflagellates are characterized by having two flagella, one lying longitudinally and the other transversely, which facilitates their movement. Not all dinoflagellates are autotrophic; some are heterotrophic or mixotrophic. They do have mitochondria, and they do not cause malaria; malaria is caused by Plasmodium, a type of protozoan, not a dinoflagellate.
