You asked: What is the smallest level of organization in the human body?

A cell is the smallest independently functioning unit of a living organism. Single celled organisms, like bacteria, are extremely small, independently-living organisms with a cellular structure. Humans are multicellular organisms with independent cells working in concert together.

What is the simplest level of organization in the body?

The human body has many levels of structural organization: atoms, cells, tissues, organs, and organ system. The simplest level is the chemical level, which includes tiny building blocks such as atoms. Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function.
