21. The Cell Theory – a timeline
Robert Hooke ( 1665)

22. Cell
Theory
1. Cells are the basic unit of structure in all living things.
(Living things are made of cells)

23. 2. Cells are the basic unit of function of all living things
(They carry out life processes)
3. All cells come from pre-existing cells.

24. Exceptions to the Cell Theory
Viruses:
not composed of cells
contain genetic information
reproduce inside host cell

25. Virus do not reproduce by division because they are not cells.

26. Did you know…
The first virus was found in both plants and animals 100 years ago.
The common cold is a type of virus.
Viruses can be treated with antiviral drugs.

27. Let’s summarize…
What do all organisms consist of?
Explain the three parts of the cell theory.
Explain why viruses are exceptions to the cell theory.

29. Review: Which statement is not a part of the cell theory?
Cells are the basic unit of structure of living things.
Cells are the basic unit of function of living things.
Cell parts such as chloroplasts are self-replicating.
Cells come from preexisting cells.

30. 2. The cell theory states that all living things are made up of
organisms
2. cells
3. tissues
4. proteins

31. 3. Which choice is NOT part of cell theory?
Cells are the basic units of life.
All living things are made of one or more cells.
All cells come from other living cells.
New cells have the same nuclei as those of pre-existing cells.
