Which is the primary site for the absorption of light

Options

A. Palisade cells
B. Guard cells
C. Mesophyll cells
D. Xylem

Explanation

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the primary site of light absorption in plants.

2. **Understand the Role of Plant Cells**: Different types of cells in plants have specific functions. For light absorption, we need to focus on the cells that are involved in the process of photosynthesis.

3. **Consider the Options**: The transcript mentions several types of cells:
- **Pellicate Cells**: Located below the epidermis, they are primarily responsible for light absorption.
- **Guard Cells**: These are responsible for regulating the opening and closing of stomatal pores, not directly involved in light absorption.
- **Mesophyll Cells**: These cells are crucial for photosynthesis but are not specifically mentioned as the primary site for light absorption.
- **Xylem**: This is involved in water transport and does not play a role in light absorption.

4. **Focus on Pellicate Cells**: The transcript indicates that Pellicate cells are the primary site for light absorption, as they work in conjunction with the epidermis and cuticle to facilitate this process.

5. **Conclusion**: The primary site for the absorption of light in plants is the Pellicate cells, which absorb light at specific wavelengths (around 680 nm and 700 nm) and initiate the process of photosynthesis.

**Final Answer**: The primary site for the absorption of light in plants is the Pellicate cells.
