A tap root will always arise from

Options

A. base of siem
B. Leaf
C. Radicle
D. Node

Explanation

### Step-by-Step Text Solution:

1. **Understanding Tap Roots**: A tap root is a type of root system characterized by a single, thick primary root that grows deeper into the soil, with smaller secondary roots branching off from it.

2. **Origin of Tap Roots**: Tap roots develop from the radical of a seed. The radical is the part of the seed that emerges first during germination and eventually forms the primary root.

3. **Formation of the Root System**:
- The radical grows into the primary root, which is the tap root.
- From the primary root, secondary roots branch out.
- Further branching can lead to the formation of tertiary roots.

4. **Evaluating Options**:
- **Base of the Stem**: Tap roots do not arise from the base of the stem.
- **Leaf**: Tap roots do not develop from leaves.
- **Radical**: This is the correct answer, as tap roots arise from the radical of the seed.
- **Node**: Tap roots do not develop from nodes.

5. **Conclusion**: Therefore, the correct answer is that a tap root will always arise from the radical of a seed.
