Options

A. Available water is more in clayey soils
B. Available water is less in clayey soils
C. Available water is more in sandy soils
D. Available water is same both in sandy and clayey soils

Answer

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

1. **Understanding Transpiration**: Transpiration is the process by which water vapor is lost from the aerial parts of the plant, primarily through small openings called stomata. It plays a crucial role in water regulation and nutrient uptake in plants.

2. **Soil Types and Water Holding Capacity**: Different types of soil have varying capacities to retain water. Clayey soils have a high water holding capacity, meaning they can retain more moisture compared to sandy soils, which have a low water holding capacity and drain quickly.

3. **Impact on Plant Growth**: Plants growing in clayey soils have access to more available water due to the soil's ability to retain moisture. This increased availability of water facilitates greater transpiration rates in these plants.

4. **Conclusion**: Therefore, plants growing in clayey soils exhibit more transpiration than those growing in sandy soils because the clayey soil retains more water, making it more available for the plants to absorb and subsequently transpire.

**Final Answer**: Plants growing in clayey soils exhibit more transpiration than those in sandy soils because clayey soils have a higher water holding capacity, providing more available water for the plants.
