1. My Cell Book (Cover)

2. Cell Theory (pg 1)
Cells were first observed in 1665 by Robert Hooke, who looked at thin slices of cork under a microscope
He saw tiny roomlike structures
He called them cells

3. Cell Theory (1 & 2)
Several scientists worked together to develop the cell theory which states:
All living things are made of cells
2.Living cells come only from other living cells

4. Cell Theory (pg 2)
3.Cells are the basic units of structure and function in all living things

5. Cell Theory (pg 3) Cells grow and divide
Because cells are so small, the microscope needed to be developed before scientists could study them

6. What are cells made of? (pg 4)
very tiny structures called organelles
While plant cells and animal cells have many of the same structures they have some that are different

7. What are cell organelles? (5)
Cell structures that carry out specific functions within the cell.
Each has a different job, but all structures must work together to keep the cell working properly.

8. *Cell membrane (Structure) pg 6

9. Describe the cell membrane
A thin covering that surrounds the cell
Made up of a double layer of lipids and numerous proteins

10. Function of Cell Membrane
Protects and supports the cell
Controls what materials enter and leave

11. Describe the Cell Wall (Structure) pg7
Ridgid wall made of cellulose
Only in plants

12. Function of Cell Wall
Found only in plant cells
Helps to support and protect the cell
Also allows materials to enter and leave

13. Cytoplasm (Structure) (pg 8)

14. Describe cytoplasm
Found in plant and animal cells
Clear, jelly-like substance
The area between the cell membrane and the nucleus
Moves constantly in cell

15. Function of the Cytoplasm
holds organelles

16. Structure & Function of the Nucleus (pg 9)
control or direct the cell's activities

17. Describe the nucleus
Found in plant and animal cells
Large, oval structure
Near center of cell

18. Mitochondria (Structure) pg 10

19. Describe the Mitochondria
Rod-shaped
Has an outer membrane and inner membrane that is folded in layers
Found in plant and animal cells

20. Function of the Mitochondria
Power House" of the cell
Break down sugars into water and carbon dioxide
Release large amounts of energy
Energy is used to power the cell

21. Endoplasmic Reticulum (Structure) pg 11

22. Describe Endoplasmic Reticulum
Found in plant and animal cells
folded membranes with or without ribosomes
Clear, tubular passageways

23. Function of the endoplasmic reticulum
carries proteins throughout the cell
“roadway”

24. Lysosomes (Structure) pg 12

25. Describe Lysosomes
Found in animal cells and sometimes in plant cells
Small round structures
digestive enzymes enclosed in a membrane

26. Function of Lysosomes
Cells cleanup crew
digest worn out cell organelles and other wastes

27. Vacuoles (Structure) pg 14

28. Ribosomes (Structure) pg 13

29. Describe Ribosomes Tiny grain like structure
Some stick to the ER others move around freely in the cytoplasm
Found in plant and animal cells

30. Make proteins and rRNA for the cell
Function of Ribosomes
Make proteins and rRNA for the cell

31. Plant cells usually have one large one
Describe Vacuoles
sacs containing water, salt, carbohydrates and proteins
Plant cells usually have one large one
Animal cells have a few small ones or none at all

32. Function of Vacuoles
Storage tanks for the cells
Store food, water and other materials
Can also store waste materials
Keep plant cells plump and firm

33. Golgi Bodies (Structure) pg 15

34. Describe Golgi bodies
Stacks of flattened sacs
Found in plant and animal cells

35. Function of Golgi bodies
package, store, modify and transport molecules (proteins)
Warehouse of cell

36. *Chloroplasts (Structure) pg 16

37. Describe Chloroplasts
Found only in plant cells
Large green structure
Contain chlorophyll - a green pigment

38. Function of Chloroplast
convert the sun's energy (sunlight) into glucose

39. Animal Cell pg 65

40. Plant Cell pg 64
