Why are cells called the basic unit of life?

Cells are called the basic unit of life because they are the smallest structures capable of performing all essential functions required for survival.

All living organisms are made up of one or more cells, and every biological process such as metabolism, growth, reproduction, and response to stimuli occurs at the cellular level.

Cells contain all necessary components, including genetic material (DNA), enzymes, and organelles, which enable them to carry out life processes independently or as part of a multicellular organism.

In unicellular organisms, a single cell performs all жизненно важные функции, while in multicellular organisms, specialized cells work together to maintain the organism.

Thus, the cell is the fundamental structural and functional unit that forms the basis of all living systems.
