Which set of pigments are involved in green plant photosynthesis

Options

A. Chlorophylls, carotenoids and anthocyanins
B. Chlorophylls, carotenoids and betacyanins
C. Chlorophylls, carotenoids and phycobilins
D. Chlorophylls, carotenes and xanthophylls.

Answer

To determine which set of pigments are involved in green plant photosynthesis, we need to analyze the options provided and identify the pigments that play a role in the process.

### Step-by-Step Solution:

1. **Identify the Options**: The question provides four options:
- Option 1: Chlorophylls, carotenoids, and anthocyanins
- Option 2: Chlorophylls, carotenoids, and betacyanins
- Option 3: Chlorophylls, carotenoids, and phycobilins
- Option 4: Chlorophylls, carotenes, and xanthophylls

2. **Analyze Option 1**:
- **Chlorophylls**: Primary photosynthetic pigments.
- **Carotenoids**: Accessory pigments that assist in photosynthesis.
- **Anthocyanins**: These pigments are found in flowers and fruits and do not participate in photosynthesis.
- **Conclusion**: This option is incorrect.

3. **Analyze Option 2**:
- **Chlorophylls**: Primary photosynthetic pigments.
- **Carotenoids**: Accessory pigments.
- **Betacyanins**: These pigments are found in beetroot and do not contribute to photosynthesis.
- **Conclusion**: This option is incorrect.

4. **Analyze Option 3**:
- **Chlorophylls**: Primary photosynthetic pigments.
- **Carotenoids**: Accessory pigments.
- **Phycobilins**: These pigments are found in some algae but are not present in higher plants.
- **Conclusion**: This option is incorrect.

5. **Analyze Option 4**:
- **Chlorophylls**: Primary photosynthetic pigments.
- **Carotenes**: A type of carotenoid that assists in photosynthesis.
- **Xanthophylls**: Another type of carotenoid that also assists in photosynthesis.
- **Conclusion**: All three pigments are involved in photosynthesis.

6. **Final Answer**: The correct set of pigments involved in green plant photosynthesis is **Chlorophylls, carotenes, and xanthophylls** (Option 4).
