Feb 28, 2021 · What you’ll learn to do: State the basic principles of the unified cell theory. 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. In this outcome we will learn about the ...
