Microfilaments perform all the following functions, except

Options

A. Provide support to plasma membrane
B. Involved in cyclosis
C. Help in cell plate method during cell division
D. Help in pseudopodia formation

Answer

To solve the question regarding the functions of microfilaments, we will analyze each option provided and determine which function is not performed by microfilaments.

### Step-by-Step Solution:

1. **Understanding Microfilaments**:
- Microfilaments are part of the cytoskeleton in eukaryotic cells and are primarily made up of the protein actin. They play various roles in cellular processes.

2. **Analyzing the Options**:
- **Option A: Provide support to plasma membrane**:
- Microfilaments do provide structural support to the plasma membrane as they are part of the cytoskeleton. This option is correct.

- **Option B: Involved in cyclosis**:
- Cyclosis refers to the movement of cytoplasm within the cell, which is facilitated by microfilaments. This option is also correct.

- **Option C: Help in cell plate method during cell division**:
- The cell plate formation occurs during plant cell division and is primarily facilitated by microtubules, not microfilaments. This option is incorrect.

- **Option D: Help in pseudopodia formation**:
- Microfilaments are indeed involved in the formation of pseudopodia, which are extensions of the cell membrane. This option is correct.

3. **Conclusion**:
- The function that is not performed by microfilaments is "help in cell plate method during cell division." Therefore, the correct answer is **Option C**.

### Final Answer:
Microfilaments perform all the following functions, except help in cell plate method during cell division.
