Formation of root hairs from apical meristem is ______.

Explanation

**Step-by-Step Solution:**

1. **Understanding Root Hairs**: Root hairs are specialized structures that arise from the epidermal cells of the roots. They are typically unicellular and elongated, which aids in their function of increasing the surface area for water and nutrient absorption.

2. **Role of Apical Meristem**: The apical meristem is located at the tips of roots and shoots. It is responsible for the primary growth of the plant, allowing it to grow in length. The apical meristem consists of actively dividing cells.

3. **Types of Apical Meristem**: There are two types of apical meristems: root apical meristem (RAM) and shoot apical meristem (SAM). The RAM is specifically responsible for the growth of roots.
