Why is cell the basic unit of life class 11?

The cell is not only the basic unit of life but it is mainly the basic structural and functional unit of life because all known organisms are made up of cells and all the functions of the body take place within the cell. This means all the biochemical processes required to live can be performed by the cells.

Is called the structural and functional unit of life?

The cell is called the structural and functional unit of life as all living organisms are made up of cells. … Furthermore, cells provide form and structure, process nutrients and convert it into useable energy. Multicellular organisms have specialized cells that perform specific functions.

What is a functional unit in anatomy?

Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.

Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

Why cell is called the basic unit of life?

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.
