So, how do cells work? At its core, a cell is a tiny, membrane-bound unit that contains genetic material, proteins, and organelles. The cell membrane is selectively permeable, allowing certain substances to pass through while keeping others out. The nucleus, found within the cell, contains the genetic instructions for growth, reproduction, and function. Mitochondria, often referred to as the powerhouses of the cell, generate energy through cellular respiration. Cells also have a complex network of channels and pumps that regulate the flow of materials in and out.
