Question

Name a process in plants that uses oxygen. Compare the raw materials and products of this process with those of photosynthesis

Answer 1

Answer:

Cellular respiration uses oxygen. Comparisons below in explanation.

Explanation:

Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).

Photosynthesis has this as its general chemical equation:

$6CO_2 +6H_2O$ ⇒ $C_6H_{12} O_6 + 6O_2$

Cellular respiration has this as its general chemical equation:

$C_6H_{12} O_6 + 6O_2$ ⇒ $6CO_2 + 6H_2O$

As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.
