Understanding Cell Theory and Function: The Basics of Life

Cell theory is fundamental to biology, stating that all living organisms are composed of at least one cell, which provides structure and function. Cells derive from preexisting cells and perform essential work necessary for life. These tiny units of life carry out various functions, including energy production through ATP, relying on specific structures to facilitate their roles. This overview explores cell structure in prokaryotes and eukaryotes, detailing how cells acquire and utilize resources to sustain life. Dive into the inner life of cells to grasp how they operate.
