Amoeba is capable of regeneration. This is possible only from

Options

A. a nucleated bit of Amoeba
B. an enucleate bit of Amoeba
C. a young Amoeba
D. an old Amoeba

Answer

To solve the question regarding the regeneration capability of Amoeba, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Recognize that Amoeba is a unicellular organism classified as a protozoan. This means it consists of a single cell that performs all necessary life functions.

2. **Regeneration Ability**: Acknowledge that Amoeba has a remarkable ability to regenerate. This means that if it is cut into pieces, each piece can potentially develop into a new, complete Amoeba.

3. **Role of the Nucleus**: Identify the importance of the nucleus in the regeneration process. The nucleus contains the genetic material necessary for cell functions and regeneration.

4. **Condition for Regeneration**: Note that for regeneration to occur, the piece of Amoeba must contain a nuclear fragment. If a piece is cut off and does not have a nucleus, it will not be able to regenerate.

5. **Conclusion**: Based on the information gathered, conclude that regeneration in Amoeba is possible only from a nucleated part of the organism. Specifically, the answer to the question is that regeneration can occur from a "nucleated beta of Amoeba."

### Final Answer:
Amoeba is capable of regeneration only from a nucleated part of the organism.
