Living things are different from nonliving things.
characteristic of life are organization, the ability to develop and grow, the ability to respond to the environment, the ability to reproduce.
An organism's body must be organized in a way that enables it to meet its needs.
Another characteristic of organisms is that the grow and, in most cases, develop into adult forms.
All living things are made of cells.
The cell is he smallest unit of a living thing.
The needs and characteristics of a single cell in a unicellular organism are the same as those for any organism.
Multicellular organisms have different types of cells that make up their body parts and help the organisms meet their needs.
The microscope led to the discovery of cells.
Most cells are microscopic, too small to see without the aid of a microscope.
Robert Hooke gave the cell its name.
The bark cells Hooke saw were actually dead cells, witch is why they appeared empty.
Cells come from other cells.
The studies of Hook and Leeuwenhoek made people ask if all living things have cells.
There was another important question scientists were trying to answer
Every living thing is made of one or more cells.
The cell theory is important to the study of biology.
Theories are important for a number of reasons.
Using a microscope to study air, water, and soil, Pasteur found microorganisms everywhere.
The work of the French scientist Louis Pasteur shows how an understanding of cell theory can have practical uses
