دردشة على الإنترنتIn plants, the water and minerals are first absorbed by the roots and then it is absorbed but the two vascular tissues namely xylem and phloem. After absorbing water and minerals, by these tissues then it is transported to all parts of plants such as stem, leaves, etc.
دردشة على الإنترنتIn plants, transpiration creates a suction pressure, as a result of which water is forced into the xylem cells of the roots. This leads to a steady movement of water from the root xylem to all the plant parts. Plants possess two transport systems to move food, water, and minerals through their roots, stems, and leaves.
