Photosynthesis is the process by which green plants use sunlight energy to make their own food. It takes place inside the chloroplasts of plant cells.

The process of photosynthesis

The word photosynthesis can be broken down into its two parts:

  • photo meaning light
  • synthesis meaning to make

So plants use light to make their own food (in the form of sugar).

The overall process of photosynthesis can be summarised by the word equation shown below.

A flow chart demonstrating the definition of an enzyme. 2 raw materials - carbon dioxide and water are added tofether.  Light is added along with chlorophyll and enzymes.  The result is 2 products - sugar and oxygen.

In reality, photosynthesis consists of a series of chemical reactions, with each reaction being catalysed by a specific enzyme.

The reactions of photosynthesis can be divided into two separate stages that take place in different locations within the chloroplast.
