Plants get nutrients from soil and sunlight .The water is absorbed from the soil by root hairs present in roots. The water and minerals absorbed by plants are transported to leaves through xylem vessels that are like pipes. Using the energy from the sun, a chemical reaction takes place in the green parts of the plant ,in which carbon dioxide and water are converted into food in the form of glucose. Oxygen is released in this process .This process is known as photosynthesis.
