Study Notes
Cell Structure and Function
- Cells are the basic units of structure and function in an organism.
- The cell is the lowest level of organization that can perform all activities required for life.
- All cells are enclosed by a membrane and use DNA as their genetic information.
Cell Types
- There are two basic types of cells: prokaryotic cells and eukaryotic cells.
Similarities between Prokaryotic and Eukaryotic Cells
- Both types of cells have DNA as their genetic material.
- Both types of cells have ribosomes.
Differences between Prokaryotic and Eukaryotic Cells
- Eukaryotic cells have a nucleus, while prokaryotic cells do not.
- Eukaryotic cells have a membrane-bound nucleus, while prokaryotic cells do not.
- Eukaryotic cells are usually multicellular, while prokaryotic cells are usually unicellular.
- Eukaryotic cells have organelles such as mitochondria and Golgi apparatus, while prokaryotic cells do not.
- Eukaryotic cells have larger ribosomes, while prokaryotic cells have smaller ribosomes.
- Eukaryotic cells have more than one chromosome, while prokaryotic cells have one, but not a true chromosome.
- Examples of eukaryotic cells include animals and plants, while examples of prokaryotic cells include bacteria and archaea.
