Mitochondria
In this Class 9 Science topic from “Cell: The Building Block of Life,” students learn how mitochondria produce usable energy for cellular activities. The topic explains their double-membrane structure, the inner folds called cristae, and the role of cellular respiration in making ATP. It also introduces why mitochondria are often called the powerhouse of the cell and highlights their ability to contain some of their own genetic material and ribosomes.
