What are the basic structural units of an organism called?

Answer 1

The cell is the basic structural unit of any living organism. One cell can be the entire organism, as with the amoeba, or millions of cells functioning together can constitute a single organism as in a human being.

Answer 2

Specialized cells come together to form tissue, groups of tissue come together to form organs, organs work together to make a working organ system, and a few different organ systems is what makes up us humans.

Cells -> tissue -> organ -> organ system -> organism

That organism can also be any other animal. For plants, they have different organs because plants are very different. Plants are producers and we are consumers, so obviously we can't be made of the same stuff.

But since you said "body," I take it you're talking about animals.

Cells are smallest, tissue next-smallest, then organ, then organ system, and the organism level is the largest.
