2. What is a cell?
The smallest unit that makes up a living thing!

3. Why study cells? Cells → Tissues → Organs → Bodies
bodies are made up of cells
cells do all the work of life!

4. The Cell Theory 1. All living things are made of cells
2. Cells are basic unit of structure and function
3. All cells come from pre-existing cells

5. Our organelles do all these jobs!
The Jobs of Cells
Cells have 3 main jobs
make energy
need energy for all activities
need to clean up waste produced while making energy
make proteins
make more cells
for growth
to replace damaged or diseased cells
Our organelles do all these jobs!

6. Organelles Organelles do the work of cells
each structure has a job to do
keeps the cell alive; keeps you alive
They’re like mini-organs!

7. 1. Cell (Plasma) Membrane
Selectively Permeable
Lets some substances in or out, but not others

8. FAT

9. The Cell Membrane is labeled A in both pictures

10. 2. Nucleus Controls cell functions Has its own membrane
Contains & Protects DNA

11. Letter B - Nucleus

13. 3. Cytoplasm
Jelly-like fluid
Moves in a circular motion within cell

16. 4. Endoplasmic Reticulum (ER)
Network of channels
Aids in transport of material around cell

17. 4. Types of E.R Rough E.R. – contains ribosomes
Smooth E.R.-make lipids, breakdown carbohydrates, detox poisons

18. Letter B - is the Endoplasmic Reticulum

19. 5. Ribosomes Site of protein synthesis Can be free or attached to E.R.
Letter C - Ribosomes

20. 6. Golgi Bodies/ Apparatus
Stacks of flattened tubes
Where proteins are completed

21. 7. Mitochondria Site of cellular respiration ATP  Energy!!!
(POWERHOUSE)

22. 8. Vacuoles LARGE in plants Hold water, food, or waste
Small in animals

23. plant cells animal cells food vacuole central vacuole
contractile vacuole

24. 9. Lysosomes digest food clean up & recycle digest broken organelles
digesting broken organelles
vacuole
small food particle
digesting food

25. A Job for Lysosomes
6 weeks
15 weeks

26. Peroxisomes
Use oxygen to break down fatty acids for use by the mitochondria.
Produce hydrogen peroxide
Found heavily in the liver

27. Organelles Only in Plant Cells
Chloroplasts
Contains green pigment - >chlorophyll
traps light energy to make food

29. 2. Cell Wall
Non-living
Supports and protects the cell
Composed of cellulose

30. A B Letter A – Cell Wall Letter B – Chloroplasts
(Where Photosynthesis Occurs) A B

31. Organelles Only in Animal Cells
1. Centrioles - used in cell division.
release spindle fibers.
