How sexual reproduction occurs in cellular slime moulds ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Cellular Slime Moulds**: Cellular slime moulds belong to the kingdom Protista and are classified as saprophytic protists. They primarily feed on decaying organic matter.

2. **Formation of Plasmodium**: Under suitable environmental conditions, these single-celled eukaryotes aggregate to form a multicellular structure known as a plasmodium. This is a crucial stage in their life cycle.

3. **Sexual Reproduction Initiation**: In the sexual reproduction phase, certain amoeboid cells within the plasmodium will undergo a process where they release spores. These spores can cluster together.
