In plants, light energy is transformed into the chemical energy of the molecules formed during photosynthesis.
These molecules are used by the plant to produce ATP during respiration. The leaf is the main photosynthetic structure. The chloroplasts are the cellular organelles within the leaf where photosynthesis takes place.
Leaves are adapted to bring together the three raw materials of photosynthesis – water, carbon dioxide and light.
These adaptations include:
Photosynthesis is a complex metabolic pathway involving many intermediate reactions. It is a process of energy transformation in which light energy is firstly changed into electrical energy and then into chemical energy.
There are three main stages to photosynthesis:
Structure and Role of Chloroplasts
Photosynthesis takes place within cell organelles called chloroplasts. They are surrounded by a double membrane.
Inside the membrane are two distinct features:
