1. Cell Structure & Function

2. Cell Theory 1.)All living things are made up of cells.
2.)Cells are the smallest working units of all living things.
3.)All cells come from preexisting cells.

3. Prokaryotes v.s. Eukaryotes
Two Cell Categories
Prokaryotes v.s. Eukaryotes
Pro=NO Eu (you)=Do
No nucleus Nucleus
No organelles Many organelles
Only Bacteria All Other Cells
Bacteria
Plant
Animal

4. The smallest unit capable of performing life functions.
Cell
The smallest unit capable of performing life functions.

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

8. Cell Parts
Organelles- Specialized structures in eukaryotic cells that perform specific functions.

9. Surrounding the Cell

10. Cell Membrane
A semi-permeable membrane controls what enters/exits the cell. (plants AND animals)

11. Cell Wall The cell wall gives the plant cell structure and support

12. Inside the Cell

13. Nucleus
The nucleus is the brain of the cell. Controls cell activities and protects the DNA

14. Chromosomes
Chromosomes (made of DNA in the nucleus) have instructions for your traits

15. Cytoplasm
Gel-like mixture called cytoplasm is surrounded by the cell membrane.

16. Endoplasmic Reticulum
The Rough Endoplasmic Reticulum moves materials around in cell (has ribosomes attached)

17. Inside the cell
The Smooth Endoplasmic Reticulum helps makes lipids

18. Inside the Cell
Mitochondria breaks down food/oxygen to create energy/power in the form of carbohydrates for the cell

19. Inside the Cell Proteins are made by the ribosomes

20. Golgi Bodies
Protein are modified, packaged, sorted and shipped by the Golgi Bodies.

21. Inside the Cell
Photosynthesis (conversion of water, sunlight, and carbon dioxide into carbs) happens in the chloroplast of only plant cells

22. Vacuoles Vacuoles are storage sacs wastes and water.

23. Lysosome Lysosomes comes from Golgi Body
They breaks down/digest: proteins, nucleic acids, carbohydrates, phospholipids
Breaks down cells when it’s time for them to die
Removes waste from cells
