A waxy layer present outside the epidermal cells is absent in

Options

A. Roots
B. Monocot leaves
C. Dicot Leaves
D. Dicot stems

Answer

**Step-by-Step Solution:**

1. **Understanding the Waxy Layer**: The waxy layer outside the epidermal cells is known as the cuticle. It serves to reduce water loss and protect the plant from environmental factors.

2. **Identifying Where the Cuticle is Present**: The cuticle is typically found on the aerial parts of the plant, such as leaves and stems. It is more prominent in dicotyledonous plants (dicots) and also present in monocotyledonous plants (monocots).

3. **Identifying Where the Cuticle is Absent**: The cuticle is generally absent in the roots of both monocots and dicots. This is because roots are primarily involved in water and nutrient absorption from the soil, and a waxy layer would hinder this process.

4. **Conclusion**: Therefore, the answer to the question "A waxy layer present outside the epidermal cells is absent in" is the roots of both monocots and dicots.

**Final Answer**: The waxy layer is absent in the roots of both monocot and dicot plants.
