Solution

The correct option is D Chlamydomonas moves away from intense light
Cyclosis is also called as cytoplasmic streaming. It is the directed movement of cytosol and organelles. Rotational cyclosis is seen in Hydrilla. Sperm movement is induced by the change in intracellular ion concentration. Sperm motility is also induced by sucrose. Flagella is a locomotory organ that is seen in slime mould along with fungi, protozoan, etc. Slime mould shows flagellar movement. Chlamydomonas move towards the light.
Thus, the correct answer is option D.
