Sporozoans have:
Correct answer: D. Neither locomotory organelle nor contractile vacuoles
- A. Both locomotory organelles and contractile vacuoles
- B. Locomotory organelles but not contractile vacuoles
- C. Contractile vacuoles but not locomotory organelles
- D. Neither locomotory organelle nor contractile vacuoles
- E. All are incorrect
Explanation
Sporozoans are a group of protists that are adapted to a parasitic lifestyle. They lack traditional locomotory organelles such as flagella or cilia, which are not necessary for their parasitic mode of life. Additionally, they do not have contractile vacuoles since they rely on their host for osmoregulation. Option D is correct as it accurately reflects these characteristics. The other options incorrectly attribute sporozoans with features they do not possess.
