Destruction of nucleus in Amoeba results in

Options

A. Immediate death
B. Slowing down of metabolic activity and ultimate death
C. Quick locomotion
D. No change.

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of the Nucleus in Amoeba:**
- The nucleus is a vital organelle in Amoeba, a unicellular eukaryote, responsible for controlling all cellular activities including metabolism, digestion, locomotion, and reproduction.

2. **Impact of Nucleus Destruction:**
- If the nucleus is destroyed, the control over these essential functions is lost. This leads to a significant disruption in the cellular processes.

3. **Immediate Effects:**
- The immediate effect of nucleus destruction is not death. Instead, the metabolic activities will begin to slow down. The nucleus regulates metabolic reactions, and without it, these processes cannot function efficiently.

4. **Slowing Down of Metabolic Activity:**
- As metabolic activities slow down, processes such as digestion, absorption, and excretion will also decline. This results in reduced energy production, which is crucial for movement and other cellular functions.

5. **Ultimate Outcome:**
- Over time, as metabolic activities continue to decline, the organism will eventually die due to the inability to sustain life processes. Therefore, while immediate death does not occur, the eventual outcome is death due to halted physiological processes.

6. **Conclusion:**
- The correct answer to the question is that the destruction of the nucleus in Amoeba results in "slowing down of metabolic activity and ultimate death."
