(a) Soil is reservoir of all mineral elements that are essential for the essential for the proper growth and development of plants.
(b) Initial uptake of minerals into the symplast is slow.
(c ) Uptake of minerals in inner space is rapid.

Options

A. All are correct
B. Only (a) is incorrect
C. (b) & (c ) are incorrect
D. Only (c ) is incorrect

Answer

To analyze the statements provided in the question, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding Statement (a)**:
- **Statement**: "Soil is a reservoir of all mineral elements that are essential for the proper growth and development of plants."
- **Explanation**: This statement is true. Soil contains a variety of mineral elements, which are categorized into macronutrients (like nitrogen, phosphorus, potassium) and micronutrients (like iron, manganese, zinc). These minerals are crucial for various physiological processes in plants.

**Hint**: Remember that soil composition directly affects plant health and growth.

2. **Understanding Statement (b)**:
- **Statement**: "Initial uptake of minerals into the symplast is slow."
- **Explanation**: This statement is incorrect. The initial uptake of minerals typically occurs in the apoplast (the outer space of the plant cells), which is a rapid process. The symplast (the inner space of the plant cells) is involved in the subsequent transport of minerals, which is slower.

**Hint**: Distinguish between apoplast and symplast pathways in mineral uptake.

3. **Understanding Statement (c)**:
- **Statement**: "Uptake of minerals in the inner space is rapid."
- **Explanation**: This statement is also incorrect. While the uptake of minerals in the inner space (symplast) does occur, it is generally slower compared to the uptake in the outer space (apoplast). The rapid uptake happens in the apoplast.

**Hint**: Recall the differences in speed and location of mineral uptake processes.

### Conclusion:
- **Final Assessment**:
- Statement (a) is correct.
- Statements (b) and (c) are incorrect.

### Summary of Findings:
- The correct answer to the question is that statement (a) is true, while statements (b) and (c) are false.
