What is the difference between protozoa and metazoa ?

Answer 1

Difference # Protozoa:

1. Protozoans are unicellular animals.

2. Protozoans are generally microscopic.

3. Acellular or body is not differentiated into cells.

4. Single cell can perform all sorts of func­tions like a complete multicellular or­ganism.

5. Single cell is capable of independent existence.

6. Body of protozoa is bounded by cell membrane or plasmalemma.
Difference # Metazoa:

1. Metazoans are multicellular animals.

2. Metazoans are generally seen in naked eyes.

3. Body of Metazoa is differentiated into cells which may transform into tissues, organs and systems in most cases.

4. Single animal can perform different types of functions by different systems in most groups.

5. Metazoan cells are interdependent and cannot survive in isolated condition.
