Photosynthesis takes place in the chloroplasts in the cells of the leaves of plants. The chloroplasts contain the chlorophyll, which absorbs sunlight.
Photosynthesis is an endothermic reaction that can be represented by word and symbol equations.
The equation for photosynthesis is carbon dioxide + water → glucose + oxygen
Energy is transferred to the plant cells by light.
The glucose produced in photosynthesis may be: • used for respiration • converted into insoluble starch for storage • used to produce fat or oil for storage • used to produce cellulose, which strengthens the cell wall • used to produce amino acids for protein synthesis
To produce proteins, plants also use nitrate ions that are absorbed in solution from the soil.
