Comparison between cellular respiration and photosynthesis

Respiration is the breakdown of glucose to make energy using oxygen. Photosynthesis Photosynthesis is the process through which plants make food for themselves in form of glucose. Respiration is where the plant takes in oxygen and releases carbon dioxide to the surroundings. This occurs all the time.

Comparison between cellular respiration and photosynthesis

Cellular respiration Photosynthesis vs. Cellular respiration Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.

They both consume and create the same substances water, glucose, oxygen, and carbon dioxide but in different ways. Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need.

They are also necessary to the energy exchange that living things need to survive. Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy. Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose.

Photosynthesis takes place in the chloroplasts of cells.

This process is what gives energy to all living organisms either directly or indirectly. Without it, life on Earth would cease to exist. Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.

It does not require the presence of sunlight and is always occurring in living organisms. Cellular respiration takes place in the mitochondria of cells.

While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.Photosynthesis occurs in the presence of light while cellular respiration is a continuous activity that likes to happen all the time.

The inputs in the photosynthesis are water and carbon dioxide while inputs in the case of cellular respiration are oxygen and glucose. Aug 24,  · As with cellular respiration, photosynthesis occurs in two stages.

The difference between the two cellular processes is that cellular respiration processes are divided into processes that require oxygen and those that do not require oxygen/5(7). Start studying Biology I- Compare & Contrast Photosynthesis and Cellular Respiration. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Photosynthesis is the process used by plants and some bacteria to create energy from sunlight.


Chlorophyll is the green pigment in plants that is responsible for this conversion process. In all other living things, they rely on the process of respiration to stay alive.

Comparison between cellular respiration and photosynthesis

Respiration is . In respiration, glycolysis takes place in the cytoplasm and oxidation of pyruvic acid takes place within mitochondria.

Generally, the rate of respiration is less than that of photosynthesis.

Key Differences Between Cellular Respiration and Photosynthesis

Definitions of photosynthesis and respiration. Photosynthesis is a process in photoautotrophs that converts carbon dioxide into organic compounds in the presence of sunlight. Respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into ATP (adenosine tri phosphate) and waste products.
