Plants are autotrophic. This means that they can create their own food. This process is called photosynthesis where in any organism has a capability to convert the light energy (usually from the sun) into chemical energy that can be used to fuels the other activities of the organism.
The main organelle responsible for the operation of photosynthesis is the chloroplast. This organelle contains the thylakoid membrane which is made up of sacks where chlorophyll is found. Chlorophyll is a pigment where in light is being captured. Chloroplast is usually found on leaves.
The overall chemical equation for the process of photosynthesis that occurs in plants can be summarized as:
`6 CO_(2) + 6 H_(2)O + light en ergy -> C_6H_12O_6 + 6 O_2`
