What is known as the basic unit of life?

The concept of the cell being the basic unit of life is foundational in biology. Cells are the smallest structural and functional units of organisms, serving as the building blocks of all living things. Each cell is capable of performing life processes and can exist independently or as part of a multicellular organism.

In terms of organization, cells can combine to form tissues, which then collaborate to create organs, and organs work together within systems in the body. This hierarchical structure illustrates how cells are integral to more complex forms of life, emphasizing their role as the fundamental unit from which all biological systems are constructed. Understanding this is essential in fields like esthetics, as it underpins knowledge about skin health and cellular regeneration.
