Choose the correct option with regard to mycorrhiza.

Options

A. Absorption of water
B. Mineral absorption
C. Translocation
D. 1 and 2

Answer

**Step-by-Step Solution:**

1. **Understanding Mycorrhizae**: Mycorrhizae is defined as a symbiotic association between fungi and the roots of plants. This relationship is crucial for the plant's nutrient uptake.

2. **Functions of Mycorrhizae**: The primary functions of mycorrhizae include:
- **Absorption of Water**: Mycorrhizae enhance the plant's ability to absorb water from the soil.
- **Mineral Absorption**: They also facilitate the uptake of essential minerals, such as phosphorus and nitrogen, which are vital for plant growth.

3. **Analyzing the Options**:
- **Option A**: Absorption of water - This is correct as mycorrhizae help in water uptake.
- **Option B**: Mineral absorption - This is also correct as mycorrhizae assist in the absorption of minerals.
- **Option C**: Translocation - This is not directly related to the function of mycorrhizae.
- **Option D**: 1 and 2 - This option combines both correct functions (water and mineral absorption).

4. **Choosing the Correct Option**: Since both options A and B are correct, the best choice is option D, which states both functions together.

5. **Final Answer**: The correct option with regard to mycorrhizae is **Option D: 1 and 2** (Absorption of water and mineral absorption).
