Some plants have additional structures associated with them that help in water and mineral) absorption. One such example is

Options

A. radical buds
B. root tubers
C. rhizoids
D. mycorrhiza

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for an example of an additional structure in some plants that aids in the absorption of water and minerals.

2. **Identifying the Correct Structure**: The correct answer to this question is "mycorrhizae." Mycorrhizae are symbiotic associations between fungi and plant roots.

3. **Explaining Mycorrhizae**: In this symbiotic relationship, the plant provides organic molecules, such as sugars, to the fungus, which are produced through photosynthesis. In return, the fungus assists the plant by absorbing water and essential minerals from the soil.

4. **Benefits of Mycorrhizae**: The mycorrhizal fungi enhance the plant's ability to absorb additional moisture and nutrients, particularly phosphorus, which is crucial for plant growth.

5. **Eliminating Other Options**:
- **Radical Buds**: These are not associated with water and mineral absorption; they are simply the initial growth from the root.
- **Root Tubers**: These serve as storage organs and do not play a direct role in the absorption process.
- **Rhizoids**: While they are structures that anchor certain plants, they do not form a symbiotic relationship for nutrient absorption like mycorrhizae do.

6. **Conclusion**: Therefore, the correct answer to the question is mycorrhizae, as they are the structures that facilitate the absorption of water and minerals in plants through their symbiotic relationship with fungi.
