Detailed explanation-1: -Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane-which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments.

Detailed explanation-2: -A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Detailed explanation-3: -1 The Cell: a basic unit of life Each cell is a self-sustainable, self-reliant unit that can replicate itself and carry on all the metabolic processes essential for the continuation of life. Each cell of both single and multicellular organisms holds the keys necessary to produce viable offspring.

Detailed explanation-4: -“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
