Respiration

Figure 7.7: Like other organisms, plants respirate to break down food, using oxygen and producing carbon dioxide. The interaction between photosynthesis, respiration, and other plant biofunctions is illustrated above. Image from URL: http://jrscience.wcp.muohio.edu/climate_projects_05

Once the plant has its food made, it still has to break that food down into useful components. As with other organisms, such as people or fish, this process, called respiration, uses oxygen and produces carbon dioxide. In plants respiration mainly takes place at night when there is no photosynthesis occurring.

The MSP project is funded by an ESEA, Title II Part B Mathematics and Science Partnership Grant through the Montana Office of Public Instruction. MSP was developed by the Clark Fork Watershed Education Program and faculty from Montana Tech of The University of Montana and Montana State University, with support from other Montana University System Faculty.
