Detailed explanation-1: -The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration)-this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.

Detailed explanation-2: -Vascular plants absorb water from the soil as a result of transpiration, in which water is lost to the atmosphere through the stomata, or plant pores that facilitate gas exchange.

Detailed explanation-3: -Plants absorb water and minerals from the soil via their roots. The root hairs on roots increase the surface area of roots to facilitate absorption of water and minerals that are dissolved in the soil water. The xylem then conducts the absorbed water and minerals from the roots to the shoot system.

Detailed explanation-4: -Osmosis, diffusion, and active transport are the three processes by which plants can absorb water and other minerals of the soil. Explanation: Osmosis: In this process, the cell wall and the cell fluid act as permeable membranes and semi-permeable membranes.

Detailed explanation-5: -The loss of water from aerial parts of the plant in the form of water vapour is termed transpiration and, when transpiration is low and absorption of water by roots is high, loss of water from leaves in the form of liquid is termed guttation.
