Mineral absorption is :

Options

A. Only active
B. Only passive
C. Both passive and active
D. Mostly passive

Answer

**Step-by-Step Solution:**

1. **Understanding Mineral Absorption**: Mineral absorption refers to the process by which plants take up minerals from the soil through their roots. This is essential for their growth and development.

2. **Types of Absorption**: There are two main types of absorption processes: active absorption and passive absorption.

3. **Active Absorption**:
- Active absorption occurs when minerals are absorbed against their concentration gradient.
- This means that the concentration of minerals inside the root cells is higher than in the surrounding soil.
- To move minerals into the roots, plants require energy in the form of ATP (adenosine triphosphate).

4. **Passive Absorption**:
- Passive absorption occurs when minerals are absorbed along their concentration gradient, meaning they move from an area of higher concentration to an area of lower concentration.
- This process does not require energy (ATP) as it relies on diffusion.

5. **Conclusion**: Since plants utilize both methods to absorb minerals depending on the concentration gradients and the type of minerals, the correct answer to the question "Mineral absorption is:" is "Both Active and Passive."

**Final Answer**: Both Active and Passive.
