which parts of a cell provide the cell with energy?

The parts of a cell that provide the cell with energy are primarily the mitochondria. Mitochondria are membrane-bound organelles known as the "powerhouses of the cell" because they generate most of the chemical energy needed to power cellular functions. They produce energy in the form of ATP (adenosine triphosphate) through cellular respiration, which involves converting energy from food molecules into ATP. This process includes breaking down glucose into carbon dioxide and water, with the energy released used to form ATP molecules that supply energy for cellular activities. In plant cells, chloroplasts also contribute by converting sunlight into chemical energy via photosynthesis, which complements the energy production role of mitochondria. Thus, mitochondria (and chloroplasts in plant cells) are the critical parts of the cell that provide energy to the cell.
