Photosynthesis and Its Requirements
Photosynthesis and Its Requirements
Photosynthesis: Green plants which are autotrophic, synthesize food through the process of ‘photosynthesis’. It is the process by which green plants having chlorophyll, synthesize the simple sugar (glucose) from simple raw materials water and carbon dioxide using the energy from the sunlight. Oxygen is released in this process. The overall equation of photosynthesis is given.The sugar produced is stored in the form of starch in plants (in animals food is stored in the form of glycogen). Since autotrophic plants are able to produce food, they are also known as ‘producers’.
Site of Photosynthesis: All green plants are capable of performing photosynthesis; the leaves are the most suitable organs for this process. The cells of the leaves contain special organelles called ‘chloroplasts’ which are the main sites of photosynthesis. These are plastids which contain light absorbing green pigment chlorophyll.
Requirements of Photosynthesis: It requires chlorophyll, carbon dioxide, water and sunlight.
