NEET BIOLOGY

Detailed explanation-1: -Capillary water makes up about 75% of the total water available to plants. It is held in the small pores of the soil.

Detailed explanation-2: -Capillary water This form of water is the most available water form made available to plants for utilization. It is the main water available to plants as they are trapped in the soil solution. Capillary water is retained in the soil by capillary action (force) which is less than the atmospheric pressure.

Detailed explanation-3: -The capillary water is the water present in the minute pores of the soil and is held against gravity for the roots of the plant to absorb. This capillary water that is present in the soil is available to the plants for uptake. Capillary water is used during root absorption in plants.

Detailed explanation-4: -It is not available to plants, because it has very low water potential (strongly negative). In other words it has very less water molecules or it is present as an extremely thin film. Water present in capillary spaces of soil is freely available to plants.

Detailed explanation-5: -Complete answer: Hygroscopic water is that which surrounds the soil particles and is held tightly to them as a thin film. It is not available to plants, because it has very low water potential (strongly negative). In other words it has very less water molecules or it is present as an extremely thin film.
