Which of the cell organelles do not contribute to the greenery of a plant?
(A) Leucoplasts
(B) Chromoplasts
(C ) Chloroplasts

Options

A. Only A
B. Both A and B
C. Both B and C
D. Both A and C

Answer

To determine which cell organelles do not contribute to the greenery of a plant, we need to analyze each option provided:

1. **Leucoplasts**:
- Leucoplasts are colorless plastids found in plant cells.
- Their primary function is to store substances such as starch, oils, and proteins.
- Since they do not contain pigments that contribute to the green color of plants, they do not contribute to the greenery.

2. **Chromoplasts**:
- Chromoplasts are colored plastids that contain pigments other than chlorophyll.
- They are responsible for the various colors in plant parts, such as the red in tomatoes or the orange in carrots.
- While they provide color, they do not contribute to the green color of plants.

3. **Chloroplasts**:
- Chloroplasts are the green plastids that contain chlorophyll, the pigment essential for photosynthesis.
- They are directly responsible for the green color of plants and contribute significantly to the greenery.

Now, let's evaluate the options:

- (A) Leucoplasts: **Do not contribute to greenery.**
- (B) Chromoplasts: **Do not contribute to greenery.**
- (C) Chloroplasts: **Do contribute to greenery.**

Based on this analysis, the correct answer to the question "Which of the cell organelles do not contribute to the greenery of a plant?" is:

**(A) Leucoplasts**.
