Cellular Respiration in Plants By Robert Korpella; Updated April 25, 2017 Cells in both plants and animals use cellular respiration as a means of converting stored energy into a chemical that individual cells consume. Adenosine triphosphate (ATP) is a chemical food that all cells use. Plants first create a simple sugar through photosynthesis. Individual cells then break down that sugar through cellular respiration.
In order to carry on cellular respiration, plant cells need oxygen and a means of disposing of carbon dioxide (just as animal cells do). Unlike animals, plants have no specialized organs for gas exchange (with the few inevitable exceptions!). The are several reasons they can get along without them: 1  Each part of the plant takes care of its own gas exchange needs. Although plants have an elaborate liquid transport system, it does not participate in gas transport. 2  Roots, stems, and leaves respire at rates much lower than are characteristic of animals.
