Study Notes
Cell and Cell Theory
- Cells are the smallest units of life.
- Modern biology is based on cell theory.
The Cell Theory
- All living things are made up of one or more cells.
- Cells are the basic units of life and carry out all life processes.
- All cells come from pre-existing cells.
Two Types of Cells:
Prokaryotes
- Cells that do not contain a nucleus or other membrane-bound organelles.
- Ex: e. coli bacteria
Eukaryotes
- Cells that contain a nucleus and other organelles, each surrounded by a thin membrane.
- Ex: Amoeba, whale, plant
- Eukaryotes have specialized parts called organelles that carry out specific functions necessary for life.
