Photo centres in higher plants are

Options

A. `P_(700)`
B. `P_(680)`
C. Both (1) & (2)
D. Chlorophyll - a

Answer

### Step-by-Step Text Solution:

1. **Understanding Photosystems**:
- Photosystems are collections of pigment molecules that absorb light energy and play a crucial role in photosynthesis. They are essential for converting light energy into chemical energy.

2. **Types of Photosystems**:
- There are two main types of photosystems in higher plants: Photosystem I (PS1) and Photosystem II (PS2).
- These systems are named based on the order of their discovery rather than their location within the plant.

3. **Reaction Centers**:
- Each photosystem has a specific reaction center that is characterized by a particular pigment.
- PS1 has a reaction center known as P700, while PS2 has a reaction center known as P680.

4. **Identifying the Options**:
- The question provides four options:
- A) P700
- B) P680
- C) Both P700 and P680
- D) Chlorophyll A

5. **Analyzing the Options**:
- Since higher plants contain both PS1 (P700) and PS2 (P680), the correct answer must include both of these reaction centers.

6. **Conclusion**:
- Therefore, the most suitable answer from the options provided is C) Both P700 and P680.

### Final Answer:
C) Both P700 and P680
