Chemical acrasin play an important role in formation of _______in some slime moulds.

Options

A. Myxamoebae
B. Pseudoplasmodium
C. Plasmodium
D. Microcyst

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Acrasin:**
- Acrasin is a chemical messenger that plays a crucial role in the behavior of slime molds. It is responsible for signaling and communication among the cells.

2. **Function of Acrasin in Slime Molds:**
- When slime molds are in a nutrient-depleted environment, acrasin accumulates, causing individual amoeboid cells to aggregate. This aggregation is essential for their survival and reproduction.

3. **Formation of Pseudoplasmodium:**
- The accumulation of cells due to acrasin leads to the formation of a structure known as pseudoplasmodium. This structure is not formed by the fusion of protoplasts (the living part of the cell) but rather by the clustering of individual cells.

4. **Distinguishing Pseudoplasmodium from Other Structures:**
- It is important to differentiate pseudoplasmodium from other structures like plasmodium, which is formed by the fusion of protoplasts, and microcysts, which are cells that can detect environmental changes.

5. **Conclusion:**
- Therefore, the correct answer to the question is that chemical acrasin plays an important role in the formation of **pseudoplasmodium** in some slime molds.
