Let's break it down:
* Cells: The smallest unit of life. They are made up of various molecules, which in turn are made of atoms. The most common atoms found in cells are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These atoms combine to form essential molecules like water, carbohydrates, lipids (fats), proteins, and nucleic acids (DNA and RNA).
* Humans: We are complex organisms made up of trillions of cells. These cells work together to form tissues, organs, and organ systems that make up our entire body. Therefore, humans are ultimately made of the same atoms that make up cells.
So, while humans are more complex than individual cells, at the most fundamental level, we are both composed of the same basic building blocks - atoms.
