Detailed explanation-1: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Detailed explanation-2: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-3: -Mitochondria are called the “power plants” of the cell because they are the site of cellular respiration. In cellular respiration, the energy from organic compounds such as glucose, is used to make ATP (adenosine triphosphate).

Detailed explanation-4: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-5: -As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration".
