Rain water is made available to crops through

Rain water is made available to crops through root absorption. When rainwater falls on the soil surface, it percolates into the soil through the tiny spaces between soil particles. As it moves down through the soil, it encounters plant roots which take up the water through a process called root absorption. Root absorption is the process by which water and nutrients are taken up by the roots of a plant. The water moves from an area of high concentration (the soil) to an area of low concentration (the root) through a process called osmosis. As the plant takes up the water, it also absorbs the dissolved nutrients in the soil, which are essential for growth and development. Once the water is absorbed by the roots, it is transported to the leaves of the plant through a system of xylem vessels. The water is then used in photosynthesis and other metabolic processes within the plant. In summary, rainwater is made available to crops through root absorption, which is the process by which water and nutrients are taken up by the roots of a plant. Once absorbed, the water is transported to the leaves of the plant through the xylem vessels and is used in various metabolic processes.
