Question

6. Class of Protozoa where adults are sedentary
a) Flagellate
b) Mastigophora
d) Suctoria
c) Ciliata​

Answer 1

The class of Protozoa where adults are sedentary is Suctoria.

• Ciliates called suctoria shed their extra cilia when they become sessile in their mature state. They eat extracellular digestion for food.
• Initially, it was believed that they were suction-fed, thus their name. They trap and control their prey using specialised microtubules.
• The majority of suctoria have a non-contractile stalk, a lorica, or shell, and are between 15 and 30 mm in length.
