How does light affect the rate of photosynthesisPaper Rating: Word Count: 1201 Approx Pages: 5
Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can be expressed as: (light) 6CO2 + 6H2O ( C6H12O6 + 6O2 (in the presence of chlorophyll)
The fact that all plants need light in order to photosynthesize has been proven many times in experiments, and so it is possible to say that without light, the plant would die.
The rate of photosynthesis and the amount of oxygen produced by a plant is affected by different factors such as light intensity, temperature, amount of water and amount of CO2. However in our experiment the main factors being tested that affect the rate of photosynthesis are light intensity, the amount of sodium hydrogen carbonate and the temperature.
How does light intensity alters and affects the rate of photosynthesis and the amount of oxygen produced in the plant weed?
I predict that as the intensity of light increases, so will the rate of photosynthesis and the amount of oxygen produced.
