Growth of tap root is

Options

A. Towards gravity
B. Towards light
C. Away from gravity
D. Away from air

Answer

To solve the question regarding the growth of the tap root, we need to understand the concepts of geotropism and phototropism.

### Step-by-Step Solution:

1. **Understanding Root Growth**: Roots are essential for plants as they anchor them to the soil and absorb water and nutrients. The growth direction of roots is influenced by gravity and light.

2. **Defining Geotropism**: Geotropism is the growth response of a plant part to gravity. Roots exhibit positive geotropism, meaning they grow towards the gravitational pull, which is downwards into the soil.

3. **Defining Phototropism**: Phototropism is the growth response of a plant part to light. Shoots typically exhibit positive phototropism, growing towards the light source.

4. **Analyzing the Options**: The question provides four options:
- Towards gravity
- Towards light
- Away from gravity
- Away from light

5. **Identifying the Correct Answer**: Since tap roots grow towards gravity (downward into the soil), the correct answer is "towards gravity."

### Final Answer:
The growth of tap root is **towards gravity**.
