The structure formed in the life cycle of cellular slime-mould due to chemotactic movement is

Options

A. Pseudoplasmodium
B. Swarm cells
C. Macrocyst
D. Capillitia

Answer

To answer the question regarding the structure formed in the life cycle of cellular slime molds due to chemotactic movement, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cellular Slime Molds**:
- Cellular slime molds belong to the kingdom Protista and are often referred to as "false fungi" due to their resemblance to fungi in some characteristics.

2. **Identifying Key Features**:
- These organisms exhibit a life cycle that includes a phase where they aggregate and move in response to chemical signals, a behavior known as chemotaxis.

3. **Recognizing the Structure Formed**:
- During the life cycle, when the amoeba-like cells (which are wall-less) come together due to chemotactic movement, they form a structure.

4. **Naming the Structure**:
- The structure formed is called **pseudoplasmodium**. This term refers to the aggregation of these cells that resemble a plasmodium but is not a true plasmodium.

5. **Eliminating Other Options**:
- The other options provided (swan cells, macrosite, capillaceae) do not relate to the structure formed by cellular slime molds during chemotactic movement.

6. **Conclusion**:
- Therefore, the correct answer to the question is **pseudoplasmodium**.

### Final Answer:
The structure formed in the life cycle of cellular slime molds due to chemotactic movement is **pseudoplasmodium**.
