The epidermis secretes a waxy coating called the __________________,which keeps water inside the leaf.a) Cortexb) Cambiumc) Epidermisd) Cuticle

To determine the correct answer, let's analyze the options given:

1. Cortex: This is the outer layer of a stem or root, which is involved in storage and transport, but not specifically related to a waxy coating that prevents water loss in leaves.

2. Cambium: This is a layer of cells in plants that divides to produce new phloem and xylem. It is crucial for growth but does not refer to a protective waxy layer.

3. Epidermis: This is the outer layer of cells in plant organs, including leaves and stems. While the epidermis plays a role in protection, it does not specifically refer to the waxy coating itself.

4. Cuticle: This is a thin layer of waxy material secreted by the epidermis that covers the surfaces of leaves and stems. It is specifically designed to reduce water loss by creating a barrier.

Final Answer

The correct answer is d) Cuticle.
