Green colour of leaves is due to presence of the pigment_____

Options

A. chlorophyll
B. mitochondira
C. ribosomes
D. chloroplast

Answer

**Step-by-Step Solution:**

1. **Identify the Question:** The question asks about the pigment responsible for the green color of leaves.

2. **Consider the Options:**
- Option 1: Chlorophyll
- Option 2: Mitochondria
- Option 3: Ribosomes
- Option 4: Chloroplast

3. **Analyze Option 1 (Chlorophyll):**
- Chlorophyll is known to be the primary pigment involved in photosynthesis.
- It absorbs light, particularly in the blue and red wavelengths, and reflects green light, which is why leaves appear green.

4. **Analyze Option 2 (Mitochondria):**
- Mitochondria are known as the powerhouses of the cell and are involved in cellular respiration, not in the pigmentation of leaves.
- Therefore, this option is incorrect.

5. **Analyze Option 3 (Ribosomes):**
- Ribosomes are responsible for protein synthesis in the cell.
- They do not play a role in the color of leaves, making this option incorrect as well.

6. **Analyze Option 4 (Chloroplast):**
- Chloroplasts are the organelles where photosynthesis occurs.
- While they contain chlorophyll, they themselves are not the pigment responsible for the green color. Thus, this option is also incorrect.

7. **Conclusion:**
- After analyzing all options, it is clear that the green color of leaves is due to the presence of the pigment **Chlorophyll**.

**Final Answer:** The green color of leaves is due to the presence of the pigment **Chlorophyll**.
