Name the part of the plant cell which traps solar energy.

Options

A. Grana
B. Stroma
C. Cuticle
D. Chlorophyll

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the part of the plant cell that traps solar energy, which is essential for the process of photosynthesis.

2. **Identifying Key Structures**: In plant cells, the organelle responsible for photosynthesis is the chloroplast. Within the chloroplast, there are specific structures that play a role in capturing sunlight.

3. **Exploring the Chloroplast**: The chloroplast is a double-membranous organelle that contains various components. The internal structure includes:
- **Stroma**: The fluid-filled space inside the chloroplast.
- **Thylakoids**: Membrane-bound structures where the light-dependent reactions of photosynthesis occur.

4. **Understanding Chlorophyll**: Chlorophyll is the green pigment found in the thylakoid membranes. It is responsible for absorbing sunlight.

5. **Conclusion**: The part of the plant cell that specifically traps solar energy is chlorophyll, which is located in the thylakoids of the chloroplast. However, if the question is asking for the structure that contains chlorophyll, then the answer would be the grana (the stacks of thylakoids).

6. **Final Answer**: The part of the plant cell which traps solar energy is **chlorophyll**, and it is located in the **grana** of the chloroplast.
