1. What is Inside a Cell?

2. cell
basic building block that makes up all living things

4. vacuole
nucleus
mitochondria
cell membrane
cytoplasm
cell membrane
chloroplasts
cell wall
vacuole
mitochondria
cytoplasm
nucleus

5. surrounds cell-holds it together
cell parts functions
cell membrane
surrounds cell-holds it together
allows materials to pass in & out of cell
nucleus
contains chromosomes (DNA)

6. between cell membrane & nucleus
cell parts functions
cytoplasm
between cell membrane &
nucleus
mitochondria
produce energy by cellular
respiration

7. vacuole stores H20 & breaks down materials cell wall
cell parts functions
vacuole
stores H20 & breaks
down materials
cell wall
(only in plants)
outside cell membrane
gives extra support &
protection
chloroplasts
(only in
plants)
uses Sun’s energy to
make food (sugar) &
oxygen

8. The cell walls of these onion skin cells can be seen in the photograph below.

10. PICTURE OF A REAL CELL MEMBRANE
It has been magnified so that we can see it!

11. The nuclei can be seen in the photograph of human cheek cells below.

14. Cells have a limit to how big or small they can be.
The Size of Cells

How Big is a Cell?

15. Time to Review!

16. cell membrane surrounds cell-holds it together
allows materials to pass in & out of cell

17. cell
basic building block that makes up all living things

18. cytoplasm
between cell membrane & nucleus

19. chloroplast found in plant cells uses Sun’s energy to
make food (sugar) &
oxygen

20. cell wall found in plants outside the cell membrane
gives extra support &
protection

21. vacuole
stores H20 & breaks down materials

22. mitochondria
produce energy by cellular respiration

23. cytoplasm

24. cell membrane

25. mitochondria

26. chloroplast

27. cell wall

28. vacuole

29. Cell parts in plants and animals

30. Cell Analogy Project
The skin on the Barbie doll is like the cell membrane of a cell because both are outside surfaces, and allow substances to pass in and out of the cell.
