Total types of chlorophyll pigments associated with PS-I and PS-II in higher plants are

Options

A. One
B. Two
C. Three
D. Four

Answer

To determine the total types of chlorophyll pigments associated with Photosystem I (PS-I) and Photosystem II (PS-II) in higher plants, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Main Types of Chlorophyll**:
- In higher plants, the primary types of chlorophyll pigments are Chlorophyll A and Chlorophyll B.
- Chlorophyll A is essential for the photosynthetic process, while Chlorophyll B assists in capturing light energy.

2. **Understand the Role of PS-I and PS-II**:
- Photosystem I (PS-I) and Photosystem II (PS-II) are two distinct complexes involved in the light-dependent reactions of photosynthesis.
- Both PS-I and PS-II primarily contain Chlorophyll A, but PS-II also contains Chlorophyll B.

3. **Count the Types of Chlorophyll**:
- In higher plants, we have:
- Chlorophyll A (found in both PS-I and PS-II)
- Chlorophyll B (found in PS-II)
- Therefore, the total types of chlorophyll pigments associated with PS-I and PS-II in higher plants are two: Chlorophyll A and Chlorophyll B.

4. **Conclusion**:
- The total types of chlorophyll pigments associated with PS-I and PS-II in higher plants are 2.

### Final Answer:
The total types of chlorophyll pigments associated with PS-I and PS-II in higher plants are **2**.
