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 Text Solution:**

1. **Understanding Mineral Absorption in Plants:**
- Mineral absorption in plants occurs in two main phases: the initial phase and the metabolic phase.

2. **Identifying the Initial Phase:**
- The initial phase is characterized by a rapid uptake of ions. This is the first step in the active intake of minerals.

3. **Rapid Uptake of Ions:**
- During this initial phase, ions are absorbed quickly into the free space of the plant cells. This free space can be referred to as the outer space where ions are exchanged.

4. **Nature of Ion Uptake:**
- The uptake of ions into the free space is generally passive. This means it does not require energy, as the ions are freely exchangeable and can move into the free space without the need for metabolic energy.

5. **Conclusion:**
- Therefore, 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: **Initial rapid uptake of ions into the free space.**
