All the following are the adaptations of land plants except :

Options

A. protection of the embryo from drying out
B. waxy cuticle on leaves to prevent drying out
C. waxy cuticle on roots to prevent drying out
D. vascular system in most plants) to move water internally

Explanation

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the adaptation that is NOT characteristic of land plants among the given options.

2. **Evaluate Each Option**:
- **Option 1: Protection of the embryo from drying out**: This is an adaptation of land plants. They have specialized structures (like seeds) that protect the embryo from desiccation.
- **Option 2: Waxy cuticle on leaves to prevent drying out**: This is also an adaptation of land plants. The waxy cuticle helps reduce water loss through transpiration.
- **Option 3: Waxy cuticle on roots to prevent drying out**: This is NOT an adaptation of land plants. If roots had a waxy cuticle, it would hinder their ability to absorb water from the soil.
- **Option 4: Vascular system in most plants to move water internally**: This is a key adaptation of land plants. The vascular system, which includes xylem and phloem, facilitates the transport of water and nutrients.

3. **Identify the Correct Answer**: Based on the evaluation, the adaptation that is NOT characteristic of land plants is the "waxy cuticle on roots to prevent drying out."

4. **Final Answer**: The correct option is the "waxy cuticle on roots to prevent drying out."
