Choose incorrect option w.r.t chloroplast

Options

A. Has enzymes for carbohydrate synthesis
B. Stroma-Light reaction
C. Has enzymes for protein synthesis
D. Thylakoid-Possess photosystem

Answer

To solve the question of identifying the incorrect option with respect to chloroplasts, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Chloroplast Function**:
- Chloroplasts are organelles found in plant cells that are primarily responsible for photosynthesis. This process converts carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) using sunlight.

**Hint**: Remember that chloroplasts are essential for photosynthesis and carbohydrate production.

2. **Analyzing the Options**:
- **Option 1**: "It has enzymes for carbohydrate synthesis."
- This statement is correct because chloroplasts contain enzymes that facilitate the synthesis of carbohydrates during the photosynthesis process.

**Hint**: Consider the role of chloroplasts in producing glucose.

- **Option 2**: "It has enzymes for protein synthesis."
- This statement is also correct. Chloroplasts are semi-autonomous organelles, meaning they have their own DNA and can synthesize some proteins independently. They contain ribosomes and enzymes necessary for protein synthesis.

**Hint**: Think about the semi-autonomous nature of chloroplasts and their ability to synthesize proteins.

- **Option 3**: "Stroma is where the light reaction occurs."
- This statement is incorrect. The light reactions of photosynthesis occur in the thylakoid membranes, not in the stroma. The stroma is where the dark reactions (Calvin cycle) take place.

**Hint**: Recall the locations of the light and dark reactions in chloroplasts.

3. **Conclusion**:
- After analyzing all the options, we find that the incorrect option is **Option 3**, which states that the stroma is where the light reaction occurs.

### Final Answer:
The incorrect option with respect to chloroplast is **Option 3**: "Stroma is where the light reaction occurs."
