All this is done through the green pigment found in plants, algae, and some bacteria called chlorophyll which absorbs the sunlight, setting into motion several complex chemical reactions that, in the end, produce sugar as well as an oxygen byproduct.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProject Overview\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhite light can be separated into different colors (or wavelengths).

This got one elementary student thinking - what effect would a different color light have on photosynthesis?

In respiration, plants break down sugar (also glucose or food) into carbon dioxide and water through a series of chemical reactions that require the use of oxygen.
