The smallest functional unit of life is the cell
The smallest functional unit of life is the cell. Cells are the basic building blocks of all living organisms, from simple single-celled organisms like bacteria to complex multicellular organisms like humans. Cells perform all the necessary functions for life, including metabolism, reproduction, growth, and responding to their environment. Each cell is enclosed by a cell membrane that separates it from its surroundings and controls the flow of substances in and out of the cell. Within the cell, various structures called organelles carry out specific functions, such as the nucleus that contains genetic material, mitochondria that produce energy, and ribosomes that synthesize proteins. Cells are diverse in terms of size, shape, and function. They can be specialized to perform specific tasks in multicellular organisms, working together to maintain the overall function and survival of the organism.
