What does Photosynthesis mean?
“photo” means light
“synthesis” means putting together
Plants need food but they do not have to wait on people or animals to provide for them. Most plants are able to make their own food whenever they need it. This is done using light and the process is called photosynthesis.
What is the Process of Photosynthesis?
Photosynthesis takes place in the leaves of plants. The leaves are made up of very small cells. Inside these cells are tiny structures called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color.
Chlorophyll absorbs the sun’s energy.
It is this energy that is used to split water molecules into hydrogen and oxygen.
Oxygen is released from the leaves into the atmosphere.
Hydrogen and carbon dioxide are used to form glucose(sugar) or food for plants.
Some of the glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants.

What is the Photosynthesis Equation?
In addition to glucose, plants also produce oxygen. This information can be written in a word equation as shown below.
