Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce carbohydrate (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.

Plants have two different types of 'transport' tissue, xylem and phloem, that move substances in and around the plant. When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.

The function of a leaf is photosynthesis – to absorb light and carbon dioxide to produce carbohydrates. The equation for photosynthesis is:

Carbon dioxide and water → glucose and oxygen

Did you know:

Leaves are the source of all of food on the planetLeaves recycle all of the world's carbon dioxide in the airLeaves contain the world's most abundant enzy
Leaves has chlorophyll which is special molecule that enables the leaf to harness the sunlight and create it to be food by Calvin cycle and release of oxygen as waste product of photosynthesis.
