Identify the group of protozoan which is not correctly matched with its feature?

• A. Flagellated- either free living or parasitic
• B. Amoeboid- move and capture their prey with the help of false feet
• C. Ciliated- actively moving organisms due to presence of cilia
• D. Sporozoans- marine forms have silica shells on their surface

Answer 1

The correct option is D Sporozoans- marine forms have silica shells on their surface

Sporozoans are infectious protozoans which have a spore-like stage in their life-cycle e.g.- Plasmodium. They do not have silica shells on their surface. It is the marine forms of amoeboid protozoans that have silica shells on their surface.
