The cell is the basic unit of all living things.
Living things are different from nonliving things.
Other characteristics of organisms is that they grow and develop into adult forms.
Characteristics of life is organization, ability to develop and grow, the ability to respond to the environment, ability to reproduce.
An organism's body must be organized in a way that enables it to meet i'ts needs.
All living things are made of cells
The cell is the smallest unit of a living thing. Some are only made up of one cell.
They are unicellular and usually too small for you to see directly.
Other organisms are made up of more than one cell. These are called multi-cellular organisms.
The microscope led to the discovery of cells.
Most cells are microscopic, which means to small to see with the naked eye.
Robert Hooke discovered the cell looking at a piece of bark from an oak tree.
The bark cells that he saw were actually dead cells, which is why they appeared empty.
Cells come from other cells.
The studies of Hooke and Leeuwenhoek made people ask if all living things have cells.
People continued to find more cells, although these cells often looked very different from each other.
People also asked where do cells come from? They then discovered that all cells divide and that's how they reproduce.
The cell theory is important to the study of biology.
All the ideas listed on this page formed a theory. A theory must be supported by evidence, including experimental evidence and observations.
Theories are important for a number of reasons. They serve as foundations for further research and study.
Louis Pasteur discovered many theories and observations. For an example, he discovered that bacteria could actually cure some diseases.
