Photosynthesis is the process by which plants, some bacteria, and some protists use sunlight, water and carbon dioxide to produce oxygen and energy in the form of sugar. The key reactions involve chlorophyll using sunlight to convert six molecules of carbon dioxide and six molecules of water into one molecule of sugar and six molecules of oxygen. A leaf functions as a solar collector containing photosynthetic cells and has structures like stomata, veins and mesophyll cells that facilitate gas exchange and transport of water and nutrients needed for photosynthesis.

8. STOMATA
Land plants must guard against

(dessication ) and so have evolved
specialized structure known as
stomata to allow gas to enter leaf
