The absorption of water is not affected when

Options

A. Soil is water logged (poorly areated )
B. Soil temperature increases
C. Soil solutionis highly concentrated
D. Soil water is available in maximum

Answer

**Step-by-Step Solution:**

1. **Understanding Water Absorption in Plants:**
- Water absorption in plants primarily occurs through root hairs. This process relies on the principle of osmosis, where water moves from an area of higher concentration (in the soil) to an area of lower concentration (inside the root cells).

2. **Identifying Factors Affecting Water Absorption:**
- Several conditions can influence the absorption of water:
- **Waterlogged Soil:** Excess water can lead to poor aeration, affecting root function.
- **Poor Aeration:** Roots require oxygen for respiration; poor aeration can hinder their ability to absorb water.
- **Increased Soil Temperature:** Higher temperatures can increase evaporation rates, reducing moisture availability.
- **Highly Concentrated Soil Solution:** A concentrated solution can create a gradient that makes it difficult for water to move into the roots.

3. **Analyzing the Given Options:**
- The question presents various scenarios regarding soil conditions and their impact on water absorption:
- **Soil is waterlogged:** This condition negatively affects absorption.
- **Poorly aerated soil:** This also negatively impacts absorption.
- **Soil temperature increases:** This can lead to increased evaporation and affect absorption.
- **Soil solution is highly concentrated:** This condition hinders water absorption due to osmotic pressure.
- **Soil water is available in maximum:** This condition supports optimal water absorption.

4. **Conclusion:**
- The absorption of water is not affected when the soil water is available in maximum. This is because the presence of sufficient water in the soil creates a favorable gradient for water to move into the plant roots.

**Final Answer:**
- The absorption of water is not affected when the soil water is available in maximum.
