Question

How the roots of the plant soak the water and transfer it to the top of the plants

Answer 1

At root tips, tiny, thin roots develop-root hairs. The plant will then seek outwater molecules in the soil. The plantwill use water potential and chemicals to draw water and nutrients to the roottips, where water is drawn to.

Answer 2

Roots absorb water by the loss and gain of ions which causes osmotic pressure difference between inside and outside of root.
Then to transport the water to the site of photosynthesis (leaves) plant uses transpiration (loss of water through evaporation from stomata)
