The protozoa are then placed into various groups primarily on the basis of how they move.

The groups are called phyla (singular, phylum) by some microbiologists, and classes by others..

What are the 4 main types of protozoa?

There are four groups of protozoa:Amoeboid Protozoans: Amoeboid protozoans live in fresh or sea water or in moist soil. … Flagellated Protozoans: Flagellated protozoans are either free-living or parasitic. … Ciliated Protozoans: These protozoans have numerous cilia on their body. … Sporozoans:

What is a virus Class 8?

Viruses are non-cellular, microscopic infectious agents that can only replicate inside a host cell. … In a nutshell, a virus is a non-cellular, infectious entity made up of genetic material and protein that can invade and reproduce only within the living cells of bacteria, plants and animals.

What is algae Class 7 short?

The green, slimy patches that grows in moist areas or stagnant water is called algae. The presence of chlorophyll in algae makes them capable to prepare their own food by process called photosynthesis.
