The variety to be found among the leaves of plants is enormous. There are large leaves, small leaves, slender leaves and wide ones.
Leaves can be soft, prickly, hairy, and hard.
But leaves all have one thing in common, they change sunlight into energy through photosynthesis. The leaves absorb carbon dioxide from the air and with water that comes through the roots of the plant, combines these elements and releases the oxygen into the air. By this exchange, plants maintain a level of oxygen in the air that benefits all living things. Management Suggestions 1.
