Question

1. what functions do the rotifer’s cilia perform?

Explanation:

Rotifers are microscopic aquatic animals. The cilia of rotifers, especially those around the mouth (corona), have two main functions: 1. Movement: The beating of cilia helps the rotifer swim through the water or move within its microhabitat. 2. Feeding: The cilia create water currents that direct food particles (like algae, bacteria, or organic debris) towards the rotifer's mouth, aiding in filter - feeding.

Answer:

The cilia of rotifers (especially the cilia in the corona region) mainly perform two functions: 1. Movement: They help the rotifer swim in water or move in its living environment. 2. Feeding: They generate water currents to direct food particles (such as algae, bacteria, organic debris) to the rotifer's mouth for filter - feeding.
