Photosynthesis - The basics of photosynthesis

Photosynthesis is the 'making of light'. The chloroplasts found in leaves absorb sunlight which converts carbon dioxide and water into glucose and oxygen.

The rate of photosynthesis

Effect of light intensity - as light intensity increases, the rate of photosynthesis increases as well. However, after a certain point, the rate would remain constant because carbon dioxide or temperature has become the limiting factor. 

Effect of carbon dioxide levels -  as carbon dioxide levels increase the rate increases as well but only up to a certain point because temperature or light has become the limiting factor. 

Effect of temperature -  as temperature is increased, the rate of photosynthesis will increase as well but if the temperature gets too high, then enzymes that speed up the reaction will lose their unique shape. This is known as 'denaturing'. When this happens the rate at which photosynthesis occurs, drops drastically.
