1. Cell Structure and Function
White Blood Cells
Red Blood Cells

2. Cell Basics Answer the following the best you can.
1) What is a cell? Give an example.
2) Draw a cell and label it’s parts

3. Cell Basics Smallest Unit of Living Things Organisms can be
Unicellular
only one cell
Multicellular
made of many cells
Amoeba: a unicellular organism
Lion: a multicellular organism

4. Cell Basics Cells can be Prokaryotic Eukaryotic Unicellular
E.coli:
Prokaryotic organism
Cells can be
Prokaryotic
Unicellular
No Nucleus (simple)
Example: Bacteria
Eukaryotic
Uni or Multicellular
Has a nucleus (complex)
Example: Lion
Tree: Eukaryotic organism

5. Cell Discovery Leeuwenhoek Hooke Invented the microscope
Made first drawings of creatures in pond water
Hooke
Early Naturalist
Named cells
From looking
at cork

6. Cell Theory All organisms are made of one or more cells
Cells are the basic units of structure and function in all living things
All cells come from already existing cells
Schleiden
Virchow
Schwann

7. Cell Size

8. Animal Cell Eukaryotic Cells Multicellular Contains cell parts
Called organelles

9. Parts of the Cell Cell membrane Outer boundary of cell
Allows only certain materials to pass through (semi-permeable)
Flexible
Made of a double layer of fats with proteins scattered throughout

10. Parts of the Cell Cytoplasm
Gel-like material inside the cell membrane and outside the nucleus
Contains water and chemicals
Where processes of the cell take place
Constantly moving

11. Parts of the Cell Nucleus Directs cell activities Includes:
DNA/Chromatin
(info to make a new cell)
Nuclear Membrane
(outside of Nucleus)
Nucleolus
(makes RNA)
Nucleoplasm
(inside of nucleus)

12. Parts of the Cell Mitochondria Powerhouse of the cell
Where sugar is broken down and energy is released
Muscle cells have large amounts of mitochondria

13. Parts of the Cell Endoplasmic Reticulum (ER) Folded Membrane
Located near nucleus
Moves materials around in the cell
Where proteins are made
Where ribosomes are located

14. Parts of the Cell Ribosome Where proteins are made Located on the ER
Can also be free-floating

15. Parts of the Cell Golgi Bodies Stacks of membrane sacs
Package and move proteins and fats to the outside of the cell

16. Parts of the Cell Lysosome
Contains chemicals that digest wastes and worn-out cell parts
Break down food

17. Parts of a Cell Vacuole Used to store water, food, and other materials
Multiple small vacuoles in animals cells
One large vacuole in plant cells

18. Plant Cell
Plant cells have specialized structures that allow them to function
Cell Wall
Chloroplast
Chlorophyll

19. Plant Cell Cell Wall Rigid outside of a plant cell
Outside of the cell membrane
Provides support for the plant
Made of cellulose

20. Plant Cell Chloroplast Where sugar is made Contains chlorophyll
Light energy, with water and carbon dioxide is converted into sugar and oxygen
Contains chlorophyll
Traps the sun light

21. Plant vs. Animal Cell Plant cells have: Animal cells have: Cell wall
Chloroplast
One vacuole
Animal cells have:
Many small vacuoles
