## How is water transported through the plant? - Water is transported from the soil through the plant to the atmosphere. First, through the roots. - The roots absorb water from the tip of the root. This is called osmosis. There are mitochondria inside the root hair cell to allow this to happen. - The water is then carried up to the leaf through the xylem. This is called transpiration. The xylem only allows substances to go one way - up. - The water is taken to the leaf and evaporated out of the leaf through the stomata which is controlled by the guard cells. ### Plant cells absorb substances from the soil. - Plant cells use osmosis to absorb water. - Plant cells use active transport to absorb mineral ions. - Active transport moves substances against the concentration gradient and needs energy. - Concentration gradient - the process of particles (sometimes called solutes) moving through a solution, from an area with a higher number of particles to an area with a lower number of particles.
