Statement l. mineral salt absortpion is an active process.
II. Explanation metabolic energy is not used in active absorption

Options

A. I is correct, II is incorrect
B. I is incorrect, II is correct
C. I and II are correct
D. I and II are incorrect

Answer

To analyze the statements provided in the question, we will break down the information step by step.

### Step 1: Understand the First Statement
The first statement is "mineral salt absorption is an active process."

- **Explanation**: Active transport is a process that requires energy to move substances against their concentration gradient. In the case of mineral salts, they are absorbed into plant roots from the soil, often against a concentration gradient, which confirms that this process is indeed active.

### Step 2: Understand the Second Statement
The second statement is "metabolic energy is not used in active absorption."

- **Explanation**: This statement contradicts the definition of active transport. Active absorption of minerals does require metabolic energy, typically in the form of ATP (adenosine triphosphate), to facilitate the movement of ions into the plant cells.

### Step 3: Evaluate the Statements
Now that we have analyzed both statements:

- The first statement is **correct** because mineral salt absorption is an active process.
- The second statement is **incorrect** because metabolic energy is indeed used in active absorption.

### Conclusion
Based on the analysis:
- The first statement is correct.
- The second statement is incorrect.

Thus, the answer to the question is: **First is correct, Second is incorrect.**
