Life Processes
How are water and animals transported in plants?
In plants the water is transported through the xylem tissue system. The xylem tissue, vessels and tracheids of the roots stems and leaves are interconnected to form a continuous system of water-conducting channels that transports water to all parts of the plant. The water and minerals are taken up from the soil by the roots. The uptake of ions at the roots creates a difference in the concentration of these ions between the root and the soil. Thus, water moves into the root from the soil to eliminate this difference. This ensures that there is a steady movement of water into root xylem, creating a continuous column of water. The root pressure is not enough to transport the water to the high parts of the plant. The transpiration from the leaves creates a Transpiration Pull, which helps in the absorption and upward movement of water and minerals dissolved in it from roots to the leaves and ensure water and minerals transport even to the highest part of the plant.
