Student B says model B is correct because carbon dioxide is a product of photosynthesis and a reactant for cellular respiration. Which student is correct and how could the model be improved? O A. Student A is correct because carbon dioxide is a reactant for photosynthesis and used to create glucose, which is used for cellular respiration and releases oxygen. The model can be improved by adding glucose next to oxygen as the other product of photosynthesis. O B. Student A is correct because carbon dioxide is a product for photosynthesis and used to create glucose, which is used for cellular respiration and releases carbon dioxide. The model can be improved by adding water next to carbon dioxide as the other product of photosynthesis. O C. Student B is correct because oxygen is a reactant of photosynthesis and is used to create glucose, which is used for cellular respiration and releases oxygen. The model can be improved by adding glucose next to oxygen as the other reactant of photosynthesis.

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
