Function . Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration.

When they require energy, they can tap the stored energy in sugar by a process called cellular respiration.

If they stop respiring, they will die.

Photosynthesis and cellular respiration are complementary biochemical reactions. The photosynthesis is considered as the basic source of energy for most of the living organisms. The respiration is an energy releasing process in many living organisms like humans, animals, birds, Plant cells respire, just as animal cells do. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis.

Only autotrophic organisms like plants, algae … Together these reactions allow cells to make and store energy and help regulate atmospheric concentrations of carbon dioxide and oxygen. The process of photosynthesis involves the use of light energy to convert carbon dioxide and water into sugar, oxygen, and other organic compounds. Photosynthesis and respiration in plants. The plants grow by photosynthesis and can be consumed as food, in addition to Food you also get oxygen and clothes from plants, etc. Photosynthesis requires the products of respiration, while respiration requires the products of photosynthesis. Plants make sugar, storing the energy of the sun into chemical energy, by the process of photosynthesis.
