Is CO2 given off during photosynthesis?

Answer 1

Plants absorb carbon dioxide by photosynthesis. They release carbon dioxide, usually at night, through respiration.

Photosynthesis is a process that uses the energy of light (photo-) to fuel the conversion of carbon dioxide and water into sugars that can then be converted into plant material (-synthesis) as well as releasing oxygen. In the process of converting the sugars created by photosynthesis into other plant material, plants consume some oxygen and release carbon dioxide. This is particularly noticeable at night or when light is low and hence photosynthesis is not occurring. This process where they release carbon dioxide instead of taking it in is known as respiration. In general, the plants release more oxygen during photosynthesis than they consume in respiration and likewise consume more carbon dioxide in photosynthesis than they release in respiration.
