IV. Multiple fission - Plasmodium
Select the correct codes.

Options

A. I, III and IV
B. I, II and III
C. II and IV
D. All of these

Answer

To solve the question regarding the correct pairs of reproduction methods and organisms, we will analyze each pair one by one.

### Step-by-Step Solution:

1. **Irregular Binary Fission - Amoeba**:
- In Amoeba, irregular binary fission occurs where the cell divides in an asymmetrical manner. The nucleus divides first (karyokinesis), followed by the cytoplasm (cytokinesis) occurring perpendicularly to the plane of the nucleus division.
- **Conclusion**: This pair is correct.

2. **Longitudinal Binary Fission - Euglena**:
- Euglena undergoes longitudinal binary fission, where the organism divides into two equal halves along its length. The nucleus divides first, followed by the division of the cytoplasm.
- **Conclusion**: This pair is correct.

3. **Transverse Binary Fission - Paramecium**:
- Paramecium reproduces through transverse binary fission, where the organism divides across its width. The macronucleus divides by amitosis, and the micronucleus undergoes mitosis, followed by the division of the cytoplasm.
- **Conclusion**: This pair is correct.

4. **Multiple Fission - Plasmodium**:
- Plasmodium reproduces through multiple fission, where the nucleus divides multiple times to produce several daughter nuclei within the same cell. Eventually, the cell bursts to release these daughter cells.
- **Conclusion**: This pair is correct.

### Final Conclusion:
All four pairs are correct. Therefore, the correct answer is that all pairs (I, II, III, IV) are correct.
