Given an equal amount of photons, what is the order of increasing effectiveness of blue, red, green, and white light (combination of the three main wavelengths) on photosynthetic activity?
1. a) Analyze the graph (Explain the meaning of the graph)
b) Which aspect of this graph has been the MOST interesting.
Photosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process.
CO2 + H2O + Light energy → C6H12O6 + O2
Considering this equation, how plant lovers (plantitos and plantitas) able to cultivate their plants?

- In this experiment, you will be monitoring changes in CO2 concentration due to aerobic respiration and photosynthesis of each test organism. Which of the following results would be expected from the conditions described? Remember this is a closed system (the CO2 cannot escape), and we are monitoring changes in CO2 concentration over a 3 minute period. A) An animal will produce a higher increase in CO2 when exposed to the light than when kept in the dark. B) A plant will cause an overall higher increase in C02 concentration when exposed to light versus an plant kept in the dark.
