Cells bearing root hairs are

Options

A. Trichoblasts
B. Colleters
C. Epiblema cells
D. Trichomes.

Answer

To answer the question "Cells bearing root hairs are", we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding Root Hairs**: Root hairs are small, tubular outgrowths that emerge from the root epidermis. They play a crucial role in the absorption of water and nutrients from the soil.

2. **Identifying the Cell Types in Root Epidermis**: The root epidermis is primarily composed of two types of cells: trichoblasts and atrichoblasts.

3. **Focus on Trichoblasts**: Among these, trichoblasts are the specific cells that give rise to root hairs. They are formed through the division of protoderm cells.

4. **Function of Trichoblasts**: Trichoblasts develop into root hairs, which are essential for the absorption of water and minerals from the soil.

5. **Conclusion**: Therefore, the cells that bear root hairs are identified as trichoblasts.

### Final Answer:
Cells bearing root hairs are **trichoblasts**.
