Don't you mean: "What is the smallest unit OF an organism and the building block of all life?"?
By the way, the answer is a cell.
atoms
Cell
All living organisms are composed of structural and functional units that are called cells. Cells are the smallest unit of life that can be replicated.
The smallest unit of a living thing that can preform all life processes is a cell.
The cell is the smallest structural unit of living organisms.
The smallest living thing (eats, excretes, responds, reproduces, utilizes energy) is a PPLO : a very small cell with (and this is only calculated) only 3 of each of the needed proteins within it's body. Bacteria appear to average ten. Thus the PPLO is precariously balanced on the very edge of being able to maintain its life functions.
The smallest unit of life are cells. Your muscles and organs consists of cells that all work to keep you alive.
a cell
Smallest unit of living thing is the cell. It is the basic unit of a living thin. Anything lower than that is not alive.A cell.cellThe smallest cell in the human body is the sperm cell. The components which make up cells cannot be considered living.A cell is the smallest unit of life that still carries out the basic processes.

It is a cell
The smallest unit of a living thing that can preform all life processes is a cell.
The smallest complete living unit known to science is a single cell. The smallest single celled organisms known, mycoplasma, are not much bigger than the very largest viruses. Viruses are not technically considered to be living organisms by most scientists.

The cell is the smallest functional unit of life. Single-celled organisms exist, but if a cell were to be taken apart it could no longer be considered "living" because it would not be functional.
hiThe cell is the functional basic unit of life.It is the smallest unit of life that is classified as a living thing, and is often called the building block of life.
