The apex of root is protected by the

Options

A. Root hair
B. Root cap
C. Meristamatic cells
D. Cells present in the region of maturation.

Answer

To answer the question "The apex of root is protected by the," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Roots**:
- The root system develops from the radical part of the seed embryo and is crucial for anchoring the plant in the soil and absorbing water and minerals.

2. **Identifying the Apex of the Root**:
- The apex of the root refers to the very tip or end of the root where growth occurs.

3. **Recognizing the Protective Structures**:
- At the apex of the root, there are specific structures that provide protection to the growing tip.

4. **Identifying the Root Cap**:
- The structure that protects the apex of the root is called the **root cap**. It is a specialized tissue that covers and protects the meristematic cells at the root tip.

5. **Role of the Root Cap**:
- The root cap not only protects the delicate meristematic cells from physical damage as the root pushes through the soil but also helps in sensing gravity and directing root growth.

6. **Following Structures in the Root**:
- After the root cap, there is the **apical meristem**, which consists of actively dividing cells. This is followed by the **zone of elongation** where cells grow in size, and finally, the **zone of maturation** where cells differentiate into various types of root cells, including root hairs.

### Final Answer:
The apex of the root is protected by the **root cap**.
