During active intake of minerals in first phase :

Options

A. An initial rapid uptake of ions into the free space
B. The ions are taken slowly into the inner space
C. The ions are taken rapidly into the inner space
D. The ions are taken slowly into the outer space

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the process of active intake of minerals during the first phase of mineral absorption in plants.

2. **Identifying the Phases of Mineral Uptake**: Mineral uptake occurs in two main phases:
- **First Phase**: This is characterized by the initial rapid uptake of ions.
- **Second Phase**: This involves a slower uptake of ions.

3. **Defining the First Phase**: In the first phase, the uptake of ions occurs rapidly into the outer space of the plant cells. This is known as the **apoplast pathway**, which is a passive process and does not require energy.

4. **Identifying the Correct Option**: The question provides options regarding the nature of the uptake in the first phase. The correct statement is that there is an initial rapid uptake of ions into the free space (which corresponds to the apoplast).

5. **Eliminating Incorrect Options**:
- The option stating that ions are taken slowly into the inner space refers to the second phase, which is incorrect for the first phase.
- Therefore, the only correct option is the one that states there is an initial rapid uptake of ions into the free space.

6. **Conclusion**: The correct answer to the question is that during the active intake of minerals in the first phase, there is an initial rapid uptake of ions into the free space.

**Final Answer**: The correct option is that there is an initial rapid uptake of ions into the free space.
