Answer & explanation
Correct answer: option 2
The correct answer is Option (2)-protoplasmic
The body of animals belonging to the phylum Protozoa, such as Paramecium, Amoeba, and Euglena, shows protoplasmic grade organization.
Explanation:
- Protozoans exhibit a simple and primitive level of organization known as a protoplasmic grade.
- In protoplasmic grade organization, the entire body functions as a single, undifferentiated mass of protoplasm.
- These organisms lack specialized tissues, organs, or distinct cell layers.
- All life processes, including digestion, locomotion, and reproduction, occur within this single cell or mass of protoplasm.
Therefore, the correct answer is protoplasmic.
