As you are doing this assingment you should constantly be thinking about WHY PHOTSYNTHESIS IS A CHEMICAL CHANGE???? What chemicals are involved in Photosynthesis? How does Photosynthesis work?
&
IS MATTER CREATED OR DESTORYED? WHY OR WHY NOT DO YOU SAY?

What is Photosynthesis?
The word photosynthesis can be separated to make two smaller words:
“photo” which means light
“synthesis” which 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.
Photosynthesis is the process by which plants make their own food. We will add more details to this definition after making a few things clear as you will see below.

To make food plants need:
- carbon dioxide
- water
- sunlight
- Carbon dioxide from the air passes through small pores (holes) in the leaves. These pores are called stomata.
- Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves.
- Sunlight is absorbed by a green chemical in the leaves.
Photosynthesis Equation
6CO2 + 6H2O --------------------> C6H12O6 + 6O2
Sunlight energy
6CO2 + 6H2O --------------------> C6H12O6 + 6O2
