1.list the 3 parts of the cell theory.
2.why is it a theory?
3.list 3 scientists and their contributions to the cell theory.
4.what do plant cells have that we do not?
5.what do animal cells have that plants do not?
6.list 3 types of microscopes and their magnification.
7.what is the difference between prokaryote and eukaryote cells.

Explanation:

1. The three parts of cell theory are: all living organisms are made up of cells, the cell is the basic unit of life, and all cells come from pre - existing cells.
2. It is a theory because it is a well - substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experimentation.
3. Matthias Schleiden concluded that all plants are made of cells. Theodor Schwann determined that all animals are made of cells. Rudolf Virchow stated that all cells come from pre - existing cells.
4. Plant cells have a cell wall, chloroplasts, and a large central vacuole that animal cells do not have.
5. Animal cells have centrioles which are generally not present in plant cells.
6. Light microscope: magnification up to about 1000x; Transmission electron microscope: magnification up to about 500,000x; Scanning electron microscope: magnification up to about 30,000x.
7. Prokaryote cells lack a nucleus and membrane - bound organelles, while eukaryote cells have a nucleus and membrane - bound organelles.
