What are two functions of a leaf?

The main function of a leaf is to produce food for the plant by photosynthesis.

Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis..

What kind of food do the plants produce?

Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
