Male and female gametes fuse in cellular slime moulds to form

Options

A. Sporangium Microcyst
B. Microcyst
C. Macrocyst
D. Spore.

Answer

To answer the question about what male and female gametes fuse to form in cellular slime molds, we can break down the process step by step:

1. **Understanding Gamete Fusion**: In cellular slime molds, male and female gametes come together to undergo fertilization. This process is crucial for sexual reproduction.

2. **Formation of a Diploid Cell**: When the male and female gametes fuse, they form a diploid cell. This cell contains two sets of chromosomes, one from each parent.

3. **Meiosis Process**: After the formation of the diploid cell, it undergoes meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid cells.

4. **Formation of Macrocyst**: During meiosis, the diploid cell develops into a structure known as the macrocyst. This is a significant stage in the life cycle of cellular slime molds.

5. **Spore Production**: Inside the macrocyst, spores are produced. These spores are haploid, meaning they contain only one set of chromosomes.

6. **Conclusion**: Therefore, the correct answer to the question is that male and female gametes fuse in cellular slime molds to form a macrocyst.

**Final Answer**: The correct option is C) macrocyst.
