8. Scientists who helped develop the
Name the 3 parts of the Cell Theory
Scientists who helped develop the
Cell Theory

9. List the 3 parts of the Cell Theory
Cells are the basic unit of life
Cells come from existing, living cells
All living things are made of 1 or more cells

10. Modern Cell Theory Why have a modern cell theory?
The energy within cells flows during cellular metabolism.
Cells contain hereditary information (DNA) that is passed on to new cells during cell division.
All cells are basically the same chemical composition in organisms of a similar species

Think: Schwann sounds like
Swan the animal

Think: Schlidin’ down the vine and vines are
plants

17. Who claimed that all cells must come from existing cells?
Hint:
Cows come from cows
Cells come from cells

Cells come from cells

19. 6th Scientist – Robert Brown
Botanist that used the term nucleus for the first time in 1833
Actually thought they were only in plant cells!

20. What determines the shape of a cell?

21. What determines the shape of a cell?
The cell’s FUNCTION!

22. ___________ is when cells perform a specific function for an organism.
Give at 3 least examples

23. Give at 3 least examples White
Cell Specialization is when cells perform a specific function for an organism.
Give at 3 least examples
Red blood cells
blood cells
Nerve cells
White

24. Name the 2 reasons cells cannot be the size of a basketball.
Red Blood Cell

25. Name the 2 reasons cells cannot be the size of a basketball.
Geometry: Volume increases faster than surface area which makes it hard for membrane to keep up with needs of the cell
Practical aspects: Nucleus can’t handle that big of a job.
