Cell and its Organelles
Introduction The cell is the fundamental unit of life, serving as the basic structural, functional, and biological unit of all known living organisms. It is the smallest unit of life capable of performing all the essential processes necessary for existence. Often referred to as the "building blocks of life," cells are the building foundation of all living things, including humans. The study of cells, known as cell biology, seeks to understand the processes and structures within cells that allow them to function and sustain life. The human body, for example, is made up of trillions of cells, each of which performs a unique and essential role. Cells provide the structure for the body, take in nutrients from food, convert these nutrients into energy, and carry out specialized functions to support the body's systems and processes. Within the cell, core organelles are involved in vital processes such as energy production, protein synthesis, waste elimination, and other ess...
