which one of the follwing fuction is not assoclated with microtubles?

Options

A. Helps in anaphasic movementof chromosomes
B. From the cytoskeleton of cilia and flagella
C. Help in pseudopodia formation
D. Spindle and astral ray formation

Answer

To solve the question "Which one of the following functions is not associated with microtubules?", we will analyze the functions associated with microtubules and identify the one that does not belong.

### Step-by-Step Solution:

1. **Understand Microtubules**: Microtubules are long, thin structures made of tubulin protein. They are a key component of the cytoskeleton in eukaryotic cells.

2. **Identify Functions of Microtubules**:
- **Cytoskeleton Formation**: Microtubules contribute to the structure and stability of the cell.
- **Spindle Fiber Formation**: During cell division, microtubules form the spindle fibers that help segregate chromosomes.
- **Cilia and Flagella Formation**: Microtubules are integral to the structure of cilia and flagella, which are involved in cell movement.
- **Chromosome Movement**: Microtubules facilitate the movement of chromosomes during anaphase in cell division.

3. **Analyze the Options**:
- **Option 1**: Help in the anaphase movement of the chromosome - This is true.
- **Option 2**: From the cytoskeleton of the cilia and flagella - This is also true.
- **Option 3**: Help in pseudopodia formation - This is incorrect as microtubules are not involved in pseudopodia formation; this function is primarily associated with actin filaments.
- **Option 4**: Spindle and astral ray formation - This is true.

4. **Conclusion**: The function that is not associated with microtubules is "Help in pseudopodia formation".

### Final Answer:
The function that is not associated with microtubules is **"Help in pseudopodia formation."**
