The plant or internal factors affecting photosynthesis are dependent on the (A)_____ and the (B)____ of the plant.

Answer

To answer the question regarding the internal factors affecting photosynthesis in plants, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

2. **Identifying Internal Factors**: Internal factors affecting photosynthesis are those that are inherent to the plant itself. These include:
- The number of leaves
- The size of leaves
- The age of the plant
- The orientation of leaves
- The structure and number of mesophyll cells
- The amount of chlorophyll present in the plant

3. **Determining Dependencies**: These internal factors are influenced by two main aspects:
- **(A) Genetic Predisposition**: This refers to the inherent genetic traits of the plant that determine its characteristics, such as leaf size, shape, and chlorophyll content.
- **(B) Growth of the Plant**: This encompasses the overall development and health of the plant, which affects how well it can perform photosynthesis.

4. **Final Answer**: Therefore, the plant or internal factors affecting photosynthesis are dependent on the (A) **genetic predisposition** and the (B) **growth of the plant**.
