Chloroplast, chromoplast, leucoplast are classified under the :-

Options

A. Plastid
B. Cytoskeleton
C. Mitochondria
D. Lysosome

Answer

**Step-by-Step Solution:**

1. **Identify the Organelles:** The question lists three types of organelles: chloroplasts, chromoplasts, and leucoplasts.

2. **Recognize Common Characteristics:** All three organelles share a common suffix "-plast," which indicates they belong to a specific category of organelles.

3. **Define the Category:** The common suffix suggests that these organelles are classified under "plastids." Plastids are specialized organelles found in plant cells and some algae.

4. **Understand the Functions of Plastids:**
- **Chloroplasts:** These plastids contain chlorophyll, which is essential for photosynthesis, allowing plants to convert sunlight into chemical energy.
- **Chromoplasts:** These plastids contain pigments that provide color to flowers and fruits, contributing to their appearance and aiding in attracting pollinators.
- **Leucoplasts:** These are colorless plastids primarily involved in the storage of food substances such as starch, oils, and fatty acids.

5. **Eliminate Other Options:** The question provides other options (cytoskeleton, mitochondria, lysosomes) that do not fit the classification of chloroplasts, chromoplasts, and leucoplasts:
- Cytoskeleton: Provides structural support to the cell.
- Mitochondria: Involved in ATP production and energy metabolism.
- Lysosomes: Contain digestive enzymes for breaking down waste.

6. **Conclude the Classification:** Based on the characteristics and functions, chloroplasts, chromoplasts, and leucoplasts are classified under "plastids."

**Final Answer:** Chloroplast, chromoplast, and leucoplast are classified under plastids.
