Chloroplasts in Hydrilla leaf show .......... movement in presence of light.

Options

A. amocboid
B. circulation
C. rotation
D. ciliary

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the type of movement that chloroplasts in Hydrilla leaves exhibit in the presence of light.

2. **Identifying the Options**: The options provided are:
- Option 1: Amoeboid
- Option 2: Circulation
- Option 3: Rotation
- Option 4: Ciliary

3. **Function of Chloroplasts**: Chloroplasts are responsible for photosynthesis, which involves gathering sunlight. Their movement is influenced by the intensity of light.

4. **Movement in Low Light**: In low light conditions, chloroplasts move towards the illuminated areas to maximize light absorption and enhance the photosynthetic rate.

5. **Movement in High Light**: In high light conditions, chloroplasts move away from direct light to avoid damage (photo damage).

6. **Type of Movement in Hydrilla**: The specific type of movement exhibited by chloroplasts in Hydrilla leaves in response to varying light conditions is rotational movement.

7. **Conclusion**: Based on the analysis, the correct answer to the question is that chloroplasts in Hydrilla leaf show **rotation** movement in the presence of light.

**Final Answer**: Chloroplasts in Hydrilla leaf show **rotation** movement in presence of light.
