1. Cell Organelles!

2. Cells
Cells are the smallest living part that make up all living things.
You and most living things are made of millions of cells.

3. Organelles Cells contain even smaller parts called organelles.
Organelles are specialized to do one function for the cell. There are many different kinds of organelles

4. Two types of cells Prokaryotes Eukaryotes Unicellular
No membrane bound structures
Bacteria
Eukaryotes
Membrane-bound structures: organelles
Mini organs

5. Eukaryote
Prokaryote

6. Plasma Membrane “city border”
Location:
Surrounding the Cell
Function:
Gives the cell shape
Protects the cell
Regulates movement of substances in and out of the cell
Found in plant and animal cells
Can see under light microscope
If you do see it under a light microscope you will not be able to see the details that you see here. We will talk about what it is made up of later

7. Ribosome “laborers” Location: Function: Present in:
Free: floating in cytoplasm
Attached: on the endoplasmic reticulum
Function:
assembles and makes proteins
Present in:
Plant and animal cells
Visible under light microscope: No

8. Mitochondria “Power Plant”
Location:
Cytoplasm
Function:
Converts food into energy
Present in:
Plant and animal cells
Visible with light microscope:
Yes (if stain is applied)

9. Golgi Apparatus “Post Office”
Location:
cytoplasm
Function:
Shipping the goods created by the Endoplasmic reticulum
Present in:
Plant and animal cells
Visible with light microscope? No

10. Rough and Smoot Endoplasmic Reticulum “Highways and road system”
Location: Cytoplasm
Present in: plant and animal
Visible under light microscope: no
Rough ER vs. Smooth ER (functions):
ER: manufacters and transports
Rough ER: has ribosomes attached
Make proteins
Smooth ER:
Make lipids
Folded like an accodian. A lot of surface area but does not take up much space. Example of accordian….

11. Chloroplast “solar energy plants”
Location: cytoplasm
Function: turn sunlight into energy
Found: plants only
See under light microscope
Yes

12. Cytoskeleton “Steel frame”
Location: within cytoplasm
Function: support of the cell
Found in:
Plant and animal
See with light microscope:
N/A

13. Cilia and Flagella Location: on the plasma membrane
Function: move cell or move items to the cell
Found: animal only
See with microscope:
Yes
Lung have cilia
Flagella=whip-like tail
Cilia=hair all over

14. Cell Wall “wall surrounding city”
Location:
Outside the cell
Function:
Protect the cell
Give the cell shape
Present in:
Plants ONLY
Visible under light microscope:
YES

15. Lysosomes “waste disposal and recycling”
Location: cytoplasm
Function:
dissolve and breakdown things like food, dead organelles, and foreign objects in the cell.
Found in:
Animal
Plant
Tadpole tails….

16. Vacuole “warehouses” Location: Function: Found in: cytoplasm Storage
Plant and animal cells
Yes… visible under a light microscope

17. Nucleus “Boss” or the “Brain”
Location: in cytoplasm
Function:
holds the genetic material, called chromosomes, in most cells.
chromosomes determine the characteristics of the cell, or individual person, plant, mushroom, or any living thing.
Located in plants and animals
Visible under microscope: YES

18. Elodea

19. Onion Cell

20. Cheek cell
