Major photosynthetic pigments in green algae are

Options

A. Chl a and b
B. Chl a,c and fucoxanthin
C. Chl a,d and phycoerythrin
D. Chl a and c.

Explanation

To answer the question about the major photosynthetic pigments in green algae, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Algae**:
- Understand that there are three main types of algae: green algae (Chlorophyceae), brown algae (Phaeophyceae), and red algae (Rhodophyceae).

2. **Determine the Photosynthetic Pigments in Each Type of Algae**:
- Green algae primarily contain chlorophyll A and B.
- Brown algae contain chlorophyll A, C, and fucoxanthin.
- Red algae contain chlorophyll A, D, and phycoerythrin.

3. **Analyze the Given Options**:
- The options provided are:
- A) Chlorophyll A and B
- B) Chlorophyll A, C, and fucoxanthin
- C) Chlorophyll A, D, and phycoerythrin
- D) Chlorophyll A and C
- From our knowledge, we can match these options with the pigments found in each type of algae.

4. **Select the Correct Answer**:
- Since green algae are known to have chlorophyll A and B, the correct answer is option A: Chlorophyll A and B.

### Final Answer:
The major photosynthetic pigments in green algae are **Chlorophyll A and B**.
