If the rate of translocation of food is slow, what will be the effect on photosynthesis

Options

A. increase
B. decrease
C. remain unchanged
D. become zero

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process primarily occurs in the leaves of plants.

2. **Defining Translocation**:
- Translocation refers to the movement of organic solutes, mainly sugars produced during photosynthesis, from the leaves (where they are synthesized) to other parts of the plant (such as stems and roots) where they are utilized or stored.

3. **Relationship Between Translocation and Photosynthesis**:
- The rate of translocation is directly proportional to the rate of photosynthesis. This means that if photosynthesis occurs at a high rate, more sugars are produced, and thus, translocation must also occur at a high rate to distribute these sugars throughout the plant.

4. **Effect of Slow Translocation on Photosynthesis**:
- If the rate of translocation of food is slow, it implies that the sugars produced during photosynthesis are not being transported efficiently to other parts of the plant. This can lead to a buildup of sugars in the leaves, which may inhibit further photosynthesis due to feedback mechanisms.

5. **Conclusion**:
- Therefore, if the rate of translocation of food is slow, the overall rate of photosynthesis will decrease. This is because the plant cannot effectively utilize the products of photosynthesis, leading to reduced efficiency in the process.

### Final Answer:
If the rate of translocation of food is slow, the rate of photosynthesis will decrease.
