NEET BIOLOGY

Detailed explanation-1: -Ciliates use cilia for locomotion, similar to the way flagella are used in flagellates.

Detailed explanation-2: -Ciliates are single-celled organisms that, at some stage in their life cycle, possess cilia, short hairlike organelles used for locomotion and food gathering.

Detailed explanation-3: -Ciliates are the largest (c.8, 000 species) and the most complex of the Protozoans. They are found in both aquatic and terrestrial habitats and many are carnivorous. Ciliates have two nuclei (macronucleus and micronucleus) and a variety of organelles, such as a cystome (mouth).

Detailed explanation-4: -Free-living ciliates may feed on bacteria, algae, or even other ciliates; Didinium, shown above, is a rapacious hunter and consumer of other ciliates. Some ciliates harbor symbiotic bacteria or algae.
