Nutrient & Water Delivery

Water and nutrients are transported through plants first through turgor pressure in which the water is fist absorbed. The soil is the source of all nutrients the plant needs which the roots soak up. Water is then transported from the roots through the rest of the plant via the xylem. Any waste is then secreted through the stomata through a process called Transpiration. The casparian strip projects the plant from losing too much water at one time.

Terms
1. Turgor Pressure- the absorption of water into the vacuoles in the cells.
2. Transpiration- process in which water is released by the plant through the stomata.
3. Xylem- tissue which transport water from the roots
4. Stomata- pores in the plant made up of guard cells which release water and other wastes such as oxygen
5. Casparian strip- blocks the passive flow of water and other wastes from leaving the plant.
