Cells are the basic structural and functional units of life. Their primary functions include:
Metabolism: Cells perform numerous chemical reactions to sustain life, including converting nutrients into energy. Growth: Cells grow by synthesizing various macromolecules and organelles. Reproduction: Cellular reproduction (mitosis and meiosis) is essential for growth, development, and tissue repair. Response to Stimuli: Cells can respond to external stimuli through receptors and signaling pathways. Homeostasis: Cells maintain a stable internal environment by regulating various physiological processes.
