The slug-like phase of the cellular slime mould life cycle is called :

Options

A. plasmodium
B. pseudoplasmodium
C. sporangia
D. macrocyst

Explanation

**Step-by-Step Solution:**

1. **Understanding the Life Cycle of Cellular Slime Moulds:**
- Cellular slime moulds undergo a complex life cycle that includes both unicellular and multicellular stages. They are primarily found in environments with decaying organic matter.

2. **Identifying the Slug-like Phase:**
- During the life cycle, when food is plentiful, individual amoeboid cells exist independently. However, when the food supply diminishes, these cells aggregate together to form a multicellular structure.

3. **Naming the Slug-like Phase:**
- This multicellular structure formed during the aggregation of amoeboid cells is known as **Pseudoplasmodium**. It is a temporary phase that allows the cells to move together in search of better environmental conditions.

4. **Characteristics of Pseudoplasmodium:**
- The Pseudoplasmodium is characterized by its ability to move and is composed of many haploid amoeboid cells. It can ooze and navigate through its environment, seeking moisture and light.

5. **Conclusion:**
- Therefore, the slug-like phase of the cellular slime mould life cycle is called **Pseudoplasmodium**.
