Explanation: 

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: -The smallest functional unit of life is cell, discovered by Robert Hooke in 1665. A cell can independently perform all necessary activities to sustain life. Hence cell is the basic unit of life.

Detailed explanation-3: -The cell is the structural and functional unit of life, and all the organisms are made up of cells of different size, shape, number and structural organization. Cells are also known as ‘building blocks of life’. The study of cell is called ‘cell biology or cytology’.
