Does photosynthesis release heat? - Quora

WebIn photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction. WebA group of pupils investigated the way in which the colour of light affects photosynthesis. The pupils: put a piece of pondweed into a test tube of water shone light from a lamp with a red light bulb onto the pondweed counted the bubbles of gas produced by the pondweed every minute for three minutes.
