<em>Daughter cells are cells that result from the division of a single parent cell. They are produced by the division processes of mitosis and meiosis. At the completion of the mitotic cell cycle, a single cell divides forming two daughter cells. A parent cell undergoing meiosis produces four daughter cells.</em>
Mitochondria are considered as the powerhouse of cell because they perform function cellular respiration process in a cell.
Cellular respiration is a process of converting the chemical energy present in nutrients into ATP which gives energy to organisms to carry out movement and physical actions.
Mitochondria performs cellular respiration process from which they can release energy present in food and nutrients.
Due to those reasons, mitochondria is called as powerhouse of cell.
