What environmental conditions are necessary to maximize the rate of photosynthesis?

Claim Evidence

Reasoning Be sure to include information on scientific principles. Use the Google slide set on Photosynthesis or your ebook as a resource.

In order to maximize the rate of photosynthesis the following environmental conditions are needed; temperature, light intensity, light wavelength and CO2 levels. ● Oxygen production is the highest when temperature is at 17 degrees celsius ● Oxygen production is the highest when light wavelength is at 450 nm ● Oxygen production is the highest when light intensity is at 40% ● Oxygen production is the highest when carbon dioxide levels are at 230 Photosynthesis is the process by which certain organisms and plants use carbon dioxide and water to harness light energy and turn it into chemical energy, which results in glucose (food for the plants/organisms) and oxygen. The chemical reaction formed when carbon dioxide and water combine during photosynthesis requires enzymes, temperature would need to remain in an appropriate range. If temperature becomes higher than that range it could cause the enzymes to denature which would stop the combination of carbon dioxide and water limiting the rate of photosynthesis. Like enzymes, chlorophyll is also needed for the combination of carbon dioxide and water, it is used to convert the carbon dioxide and water to glucose. Chlorophyll pigments are absorbed at 450 nm of light wavelength, causing the rate of photosynthesis to maximize because more chlorophyll is being absorbed. Light is needed to convert carbon dioxide and water to glucose and oxygen, without light there is no production of food for plants meaning no photosynthesis. In order to maximize the rate of photosynthesis you would need the light intensity to stay between a certain range to continue the conversion of carbon dioxide and water to glucose and oxygen. Carbon Dioxide is used as a reactant for photosynthesis, therefore, the higher the carbon dioxide levels, the higher the rate of photosynthesis....
