Flagella of prokaryotic and eukaryotic cells differ in

Options

A. location in cell and mode of functioning
B. type of movement and placement in cell.
C. microtubular organization and functioning
D. microtubular organization and type of movement

Answer

### Step-by-Step Solution:

1. **Definition of Flagella**:
- Flagella are microscopic, hair-like structures that facilitate locomotion in cells.

2. **Basic Structure**:
- Flagella have a whip-like appearance and are involved in the movement of the cell.

3. **Differences in Prokaryotic and Eukaryotic Flagella**:
- The primary distinction between prokaryotic and eukaryotic flagella arises from the cellular organization, particularly the presence of a true nucleus in eukaryotes and a nucleoid region in prokaryotes.

4. **Microtubular Organization**:
- Prokaryotic flagella have a microtubule arrangement known as the "9 + 2" structure, which consists of 9 outer microtubules and 2 central microtubules.
- Eukaryotic flagella, on the other hand, exhibit a "9 + 0" arrangement, which has 9 outer microtubules but lacks the central pair.

5. **Type of Movement**:
- Prokaryotic flagella exhibit a rotatory movement, allowing them to propel the cell forward.
- Eukaryotic flagella display a bending motion, which is more wave-like and allows for different types of movement.

6. **Conclusion**:
- In summary, the flagella of prokaryotic and eukaryotic cells differ in their microtubular organization, type of movement, and overall structure.
