Question

how water enter continuously in root xylem​

Answer 1

Explanation:

Plants require water to carry out photosynthesis and other activities . The continuous flow of water in root xylem is due to transpiration pull. The water is lost through the stomata is replaced by xylem vessel . Evaporation of water molecules cells of cells of leaf creates a suction which pulls water from the xylem of roots to leaves. <br> Thus , transpiration helps in absorption and upward moward movement of water and minerals dissolved in it from roots to learn. <br> Cells of roots are in close contact with soil and so actively take up ions by diffusion . The ion-concentration inside the root and hence osmotic pressure increases the movement of water from soil into root which occurs continuously.
