The waxy layer covers the leaf epidermis on

Options

A. Adaxial surface only
B. Abaxial surface only
C. Both surfaces
D. Lower surface only

Answer

To solve the question regarding the waxy layer that covers the leaf epidermis, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Waxy Layer**: The waxy layer that covers the leaf epidermis is known as the **cuticle**. This is a protective layer that helps prevent water loss from the leaf surface.

2. **Determine the Location of the Cuticle**: The cuticle is present on both surfaces of the leaf. Specifically, it covers:
- The **adaxial surface** (upper surface) of the leaf.
- The **abaxial surface** (lower surface) of the leaf.

3. **Understand the Functions of Each Surface**:
- The **adaxial surface** is primarily specialized for capturing light, which is essential for photosynthesis.
- The **abaxial surface** is specialized for gaseous exchange, allowing for the intake of carbon dioxide and the release of oxygen.

4. **Evaluate the Options**: The question likely provides multiple-choice answers regarding which surface the cuticle covers. The options may include:
- Adaxial surface only
- Abaxial surface only
- Both surfaces
- Lower surface only

5. **Select the Correct Answer**: Since the cuticle covers both the adaxial and abaxial surfaces, the correct answer is **both surfaces**.

### Final Answer:
The waxy layer (cuticle) covers the leaf epidermis on **both the adaxial and abaxial surfaces**.
