How does water move through a plant?
Water moves into the roots of a plant through osmosis. Osmosis is the net movement of solvent molecules down a concentration gradient through a partially permeable membrane.
In here, the water-rich soil has a high water concentration, while the roots have low water concentration. So, water moves into the roots/root hair cells of the plants through osmosis, and passes through the cell membrane of the roots.
From this picture, you can see the path taken by water and into the plant:
