Question

When does water enter in roots?​

Answer 1

Answer:

Cells of roots are in close contact with soil and so actively take up ions by diffusion. The ion-concentration increases inside the root and hence osmotic pressure increases the movement of water from soil into root which occurs continuously.

Answer 2

Answer:

Water is found in the spaces between the soil particles. Water and mineral salts first enter through the cell wall and cell membrane of the root hair cell by osmosis. Root hair cells are outgrowths at the tips of plants' roots. They function solely to take up water and mineral salts.
