What Is The Smallest Unit Of Living Matter?

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.

What is the smallest unit of living matter quizlet?

Who said atoms are the smallest unit of matter?

chemist John Dalton

Dalton’s Atomic Theory. The modern atomic theory proposed about 1803 by the English chemist John Dalton (Figure 2.1. 4) is a fundamental concept that states that all elements are composed of atoms. Previously an atom was defined as the smallest part of an element that maintains the identity of that element.
