1. Cell Structure & Function

2. Cell Theory Recap All living things are made up of cells.
Cells are the smallest working units of all living things.
All cells come from preexisting cells through cell division.

3. Definition of Cell
A cell is the smallest unit that is capable of performing life functions.

4. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

5. Prokaryotic Eukaryotic
Two Types of Cells
Prokaryotic
Eukaryotic

6. Prokaryotic Recap Pro-NO
Do not have structures surrounded by membranes
Few internal structures
One-celled organisms, Bacteria
NO What?

7. Eukaryotic Recap You- Do
You do what?
Contain organelles surrounded by membranes
Most living organisms
Animal
Plant

8. “Typical” Animal Cell

9. “Typical” Plant Cell

10. Cell Parts
Organelles

11. Surrounding the Cell

12. Cell Membrane Selectively Permeably Outer membrane of cell
Double layer of fats called lipids
“they look like two tailed sperm”
Function: controls movement in and out of the cell
Selectively Permeably
Only lets SOME things in
Only lets SOME things out,
Not all

13. Cell Wall Most commonly found in plant cells & bacteria
Function: Supports & protects cells

14. Inside the Cell

15. Nucleus Function: Directs cell activities
Separated from cytoplasm by nuclear membrane
Contains genetic material - DNA

16. Cytoplasm Gel-like mixture Surrounded by cell membrane
Contains hereditary material

17. Ribosomes Each cell contains thousands Function: Make proteins
Basically they make you!

18. Mitochondria
All about sophia
Function: Produces energy through chemical reactions – breaking down fats & carbohydrates

19. Chromosomes In nucleus Made of DNA
Function: Contain instructions for traits & characteristics

20. Lysosome
Function: Digestive 'plant' for proteins, fats, and carbohydrates
Transports undigested material to cell membrane for removal
Cell breaks down if lysosome explodes

21. Vacuoles
Function: Membrane-bound sacs for storage, digestion, and waste removal
Contains water solution
Help plants maintain shape

22. Chloroplast Usually found in plant cells Contains green chlorophyll
Function: Where photosynthesis takes place

23. Who has organelle? Pro Euk Have: Ribosomes Mitochondria All of them!
Both Prokaryotes and Eukaryotes
Pro
Euk
Way fewer organelle
Have:
Ribosomes
Mitochondria
All of them!

24. What happens if a Lysosome explodes in a cell?
THE BREAKS DOWN
CANT EAT/NO ENERGY
