Cycle of Photosynthesis & Respiration

The process by which plants make food is called "photosynthesis". The word "photosynthesis" is made up of two words: 1.	"photo" = light 2.	"synthesis" = putting together

Plants take in carbon dioxide from the air and water from the soil; put them together (in the presence of light energy and chlorophyll) to produce sugar (glucose) and oxygen.

Chlorophyll is the green pigment found in plants. Both chlorophyll and light energy need to be present for photosynthesis to take place, but they are not used up in the process.

Thus, the process of photosynthesis can be represented as follows:

cabondioxide carbon dioxide + water    →→→→→→→→     sugar (glucose) + oxygen light energy
