♤ They are the part of the tree that converts energy into food (sugar).
♤ Leaves are the food factories of a tree.
♤ They contain a very special substance called chlorophyll. It is chlorophyll that gives leaves their green colour.
♤ Chlorophyll is an extremely important biomolecule, used in photosynthesis. leaves use the sun’s energy to convert carbon dioxide from the atmosphere and water from the soil into sugar and oxygen.
♤ The sugar, which is the tree’s food, is either used or stored in the branches, trunk and roots. The oxygen is released back into the atmosphere.
