What will happen to the rate of photosynthesis if rate of translocation of food is slow the photosynthesis rate ?

Options

A. 1)Becomes double
B. 2)Decreases
C. 3)Increases
D. 4)Remains same

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy in the form of glucose (food) using carbon dioxide and water. This process occurs primarily in the leaves.

2. **Understanding Translocation**: Translocation refers to the movement of the products of photosynthesis (mainly carbohydrates) from the leaves, where they are produced, to other parts of the plant (such as roots, stems, and fruits) where they are utilized or stored.

3. **Relationship Between Photosynthesis and Translocation**: The products of photosynthesis (carbohydrates) need to be transported to different parts of the plant. If the rate of translocation is slow, it means that the carbohydrates produced during photosynthesis are not being moved efficiently to where they are needed.

4. **Impact of Slow Translocation**: When translocation is slow, the carbohydrates produced during photosynthesis accumulate in the leaves. This can lead to a decrease in the availability of carbohydrates for respiration in other parts of the plant.

5. **Respiration and Its Role**: Respiration is the process by which plants convert carbohydrates into energy for growth and maintenance. If translocation is slow, respiration in other parts of the plant will also slow down because there is less carbohydrate available for this process.

6. **Conclusion**: Since respiration is slowed down due to the accumulation of carbohydrates in the leaves, the overall demand for photosynthesis decreases. Therefore, the rate of photosynthesis will also decrease.

7. **Final Answer**: The correct answer is that the rate of photosynthesis decreases.
