The water and mineral nutrients move up from the plant's roots to its leaves through xylem. There are 3 steps. 1. water vapor diffuses out of a leaf-transpiration. 2. the cohesion of water molecules causes water molecules that are being lost by a plant to pull on the water molecules still in the xylem. 3. roots take in water from the soil by osmosis.
There are three steps that plants take in order to transport water. The water diffuses from a leaf transpiration. Then the water molecules are lost by the plant in order to get molecules from the xylem. The roots then take in water from the soil.
When the stomata open, water vapor diffuses out of a leaf. Then, water is drawn upward in the same way that liquid is drqwn through a siphon. Finally, the roots take in the water from the soil by osmosis.
