In addition to sunlight, they need carbon dioxide and water.
Photosynthesis involves multiple chemical reactions that happen in a series, so that the end result of one chemical reaction supports the next reaction.
The last stage in the photosynthesis process involves taking in sunlight.
As plants absorb sunlight, a chemical reaction takes place where molecules of carbon dioxide and water are broken down.
Other plants, like lily pads, have unique structures to help collect water.
Plants can absorb carbon dioxide from pores in their roots, flowers, leaves, branches and stems.The amounts of water, carbon dioxide, sunlight and temperature.The amount of water is effected by how much is taken up through the roots and how much is lost from the leaves.The formula for photosynthesis is 6CO2 6H2O light energy = C6H12O6 6O2.In words, the equation translates to the combining of water, carbon dioxide and light energy to produce glucose and oxygen.Trees and plants can also reduce energy bills for homeowners, as the shade that they provide cools homes and can lower the cost of an energy bill.See the section on for more details on plant structure.One amazing feature of leaves is that they have tiny holes in them to let the gases carbon dioxide and oxygen enter and exit.One of the holes is called a 'stoma', although just to be confusing, when there are more than one they are called 'stomata'. It is controlled by two guard cells which change shape to either open or close the hole.This creates carbohydrates, or glucose, which is sugar that the plants can store and use later for energy.The other end product of this phase is oxygen, which plants release back into the atmosphere.
