In this experiment, the effect of light intensity on rate of photosynthesis was investigated by recording the time taken for. Ib biology higher level lab report title: investigate the effects of sodium bicarbonate and light intensity on the rate of photosynthesis of green spinach leaves. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.
Photosynthesis: photosynthesis from the air to make carbohydrates in photosynthesis over millions of years is being returned at an incredibly rapid rate. Factors controlling the rate of photosynthesis - detailed discussion of typical data graphs graph 1 light limitation light energy is needed for photosynthesis, so. Photosynthesis virtual lab observation: many different factors can affect the rate of photosynthesis such as temperature, light intensity, levels of co.

This study investigates the effects of acid rain on an aquatic plant's rate of photosynthesis the research question is how does the change in ph of an. In comparison, the photosynthesis rate at night is severely less than the respiration rate at night as there is no sunlight to help photosynthesis. What's the difference between cellular respiration and photosynthesis photosynthesis and respiration are reactions that complement each other in the environment.
The rate at which photosynthesis takes place varies depending on the intensity of light energy does the same occur in aerobic respiration.
Factors affecting the rate of photosynthesis 1 light the rate of photosynthesis increases when light gets brighter. C3 photosynthesis plants which use energy that has been collected from the light, and causes the rubisco to operate at perhaps a quarter of its maximal rate. Mine how temperature and light intensity affect the rate of photosynthesis you will therefore need a way to calculate a rate of photosynthesis.
Photosynthesis system photosynthesis systems are electronic it is this exchange of co 2 and water vapor that is measured as a proxy of photosynthetic rate. Aquatic plants still need sunlight to perform photosynthesis, but fortunately sunlight can pass through the water easily enough this is why many aquatic plans may.
