Plants are an important part of everyday life. They provide us with oxygen which is essential for us to live. In addition plants help clean the air by taking in carbon dioxide. They do this through a process called photosynthesis. Photosynthesis is the process when plants take in water, carbon dioxide and energy from the sun and make food for themselves in the form of glucose and also release oxygen into the atmosphere. They do this process inside the chloroplasts which are inside each plant cell. Chlorophyll is a pigment found inside the chloroplast that gives plants their green color. Plants also help with another process called nitrogen fixation which means they change the nitrogen gas in the air to a more useable form for animals.
