(ii) Initial uptake of mineral is passive
(iii) Entry or exit of ions to and from inner space does not require energy.

Options

A. I,ii and iii correct
B. ii and iii correct
C. I and ii correct
D. I and iii correct

Answer

To analyze the statements regarding mineral absorption, we can break down the process into two main phases and evaluate each statement accordingly.

### Step-by-Step Solution:

1. **Understanding the Phases of Mineral Absorption**:
- Mineral absorption occurs in two distinct phases: the first phase involves rapid uptake of ions into the free space, and the second phase involves a slower uptake into the inner space of the cells.

2. **First Phase - Rapid Uptake**:
- In the first phase, there is a rapid uptake of ions into the free space (also known as the apoplast). This process is characterized by passive transport, meaning it does not require energy. The ions move along their concentration gradient into the outer space of the cells.

3. **Second Phase - Slow Uptake**:
- The second phase involves the movement of ions from the free space into the inner space of the cells (the symplast). This process is slower and requires energy, as it involves active transport mechanisms. Here, ions move through ion channels and transmembrane proteins, which selectively allow certain ions to pass through.

4. **Evaluating the Statements**:
- (i) "There is rapid uptake of ions into free space in its first phase." - This statement is **correct** as it describes the first phase accurately.
- (ii) "Initial uptake of mineral is passive." - This statement is also **correct** because the initial uptake in the first phase does not require energy.
- (iii) "Entry or exit of ions to and from inner space does not require energy." - This statement is **incorrect** because the movement of ions into the inner space requires energy, indicating that it is an active process.

5. **Conclusion**:
- The correct statements are (i) and (ii), while statement (iii) is incorrect.

### Final Answer:
- The correct statements regarding mineral absorption are (i) and (ii).
