1. DO NOW: Cell Factory Analogy

2. Cells

3. All cells have… 1. Cell membrane 2. Hereditary material 3. Cytoplasm
4. Ribosomes
************************************

4. Cytology
Study of cells

5. smallest unit that is capable of performing life functions.
Cell
smallest unit that is capable of performing life functions.
The shape of a cell tells you about the ____________ of the cell.
function

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

7. Prokaryotic Eukaryotic
Two Types of Cells
Prokaryotic Eukaryotic
Use page 39 in your text books to
sketch a drawing and label each!

8. Prokaryotic No membrane-bound organelles No defined nucleus (nucleoid)
Single-celled

9. Eukaryotic Membrane-bound organelles Cell wall- plants ONLY! Plant
Animal

10. “Typical” Animal Cell

11. “Typical” Plant Cell

12. Cell Wall found in plant cells & bacteria Supports & protects cells
Made of a starch/carbohydrate called cellulose

13. Cell Membrane Maintains homeostasis Selectively permeable
Made of proteins, carbs, and lipids

14. Fluid Mosaic Model

15. Cytoplasm Gel-like mixture Surrounded by cell membrane
Holds the organelles
Contains the cytoskeleton
Which gives the cell shape
Cytoplasm

16. Nucleus Directs ALL cell activities Contains hereditary material
Separated from cytoplasm by nuclear membrane
Nucleolus makes RNA
Nucleus

17. Chloroplast Photosynthesis! Contains green chlorophyll
Mostly found in plant cells

18. Mitochondria Cristae Energy (ATP) Does cellular respiration
Internal membrane called cristae
Breaks down proteins, fats, and carbohydrates to be used as energy
Cristae

19. Ribosomes Each cell contains thousands Make proteins
Found floating in the cytoplasm or attached to the rough ER
Made by the nucleolus

20. Endoplasmic Reticulum
Moves materials around in cell
Smooth: no ribosomes- makes lipids
Rough: has ribosomes- makes proteins
Ribsomes help
make proteins

21. Golgi Bodies Material 'packaging plant'
Packages substances in vesicles

22. Vacuole Used for storage, digestion, and waste removal
Help plants maintain shape
Large vacuole in plant cells
Small vacuole in animal cells

23. Lysosome Digests proteins, fats, and carbohydrates
Why is it important the lysosome has a membrane?
Cell breaks down if lysosome explodes

24. Centrioles Help with cell division Only found in animal cells
Located near nucleus

25. Organization
Work with a partner to fill in the last couple of blanks on the back of your notes!!
