Similarity between, plant and animal flagella microtubules -

Options

A. 9 + 3
B. 9 + 2
C. 9 + 6
D. 9 + 1

Answer

To answer the question about the similarity between plant and animal flagella microtubules, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Flagella Structure**:
- Both plant and animal flagella are composed of microtubules, which are structural components of the cytoskeleton.

2. **Identify the Microtubule Arrangement**:
- The eukaryotic flagellum, which includes those found in both plants and animals, typically exhibits a characteristic arrangement known as the "9 + 2" structure. This means there are 9 pairs of microtubules arranged in a circle, surrounding 2 central microtubules.

3. **Compare Plant and Animal Flagella**:
- While there are differences in the overall function and presence of flagella in plant and animal cells (e.g., flagella are more common in animal cells), the microtubule arrangement remains consistent. Both types of flagella contain the "9 + 2" microtubule structure.

4. **Conclusion**:
- The similarity between plant and animal flagella microtubules is that both have the "9 + 2" arrangement of microtubules.

### Final Answer:
The similarity between plant and animal flagella microtubules is that both exhibit the "9 + 2" arrangement of microtubules.
