1 DO NOW: Element Molecule Organelle Cell Tissue Organ Organ System
Organism DO NOW: Organize the following terms from smallest to largest. Cell Organ Organelle Molecule Organ System Tissue Organism Element

2 Let’s Review the Types of cells
bacteria cells Prokaryote - no organelles Eukaryotes - organelles animal cells plant cells

3 Cells & Cell Organelles
Doing Life’s Work

4 Why study cells? Cells  Tissues  Organs  Bodies
bodies are made up of cells cells do all the work of life!

5 Cell membrane Structure Function double layer of fat
phospholipid bilayer Includes receptor molecules Function separates cell from outside controls what enters or leaves cell recognizes signals from other cells allows communication between cells

6 Cell Wall Structure: Function:
Rigid layer surrounding the cell membrane in plants, algae, fungi, and most bacteria Function: Provides support Protection Prevents over-expansion of cell

7 Cytoplasm Structure: Function jelly-like fluid
Holds organelles in place Helps to transport materials

8 Nucleus Structure Function nuclear membrane
Contains: nucleolus and chromosomes (DNA) Function control center of cell protects DNA

9 Nuclear Envelope Structure: Function: Double lipid bilayer
Surrounds genetic material and nucleolus

10 Nucleolus Structure: Function: Inside nucleus Surrounded by membrane
Ribosome Factory

11 Chromatin Structure: Function: Made up of DNA and proteins
Forms chromosomes within the nucleus of eukaryotic cells

12 Ribosomes Function Structure
Link amino acids together to from proteins AKA protein factories read instructions to build proteins from DNA Structure some free in cytoplasm some attached to ER Ribosomes on ER

13 Endoplasmic Reticulum
Function & Structure: Rough ER ribosomes attached helps produce proteins Smooth ER makes lipids for membranes

14 Microtubules Structure: Function: Tube shaped
Made of protein and tubulin Function: Responsible for movement within the cell

15 Microfilaments Structure: Function:
Thin, twisted proteins in the cytoplasm of eukaryotes Function: Keep organelles in place Help with cell movement

16 Vacuoles Structure Function: food vacuole Membrane Sac Large in plants
Storage of materials Moves materials around cell food vacuole

17 Mitochondria Structure: Function Double Membrane
Supply energy to the cell by converting molecules from food into usable energy

18 Golgi Apparatus Structure Function membrane sacs
finishes, sorts, labels & delivers proteins like UPS headquarters shipping & receiving department ships proteins in vesicles “UPS trucks” vesicles carrying proteins transport vesicles

19 Chloroplasts Structure: Function: Stacks of disc-shaped sacs
Inner and outer membranes Function: Carry out photosynthesis to convert solar energy into energy-rich molecules (sugar) Helps to grow plant

20 Lysosomes Structure membrane sac of digestive enzymes Function
digest food used to make energy clean up & recycle lysosomes

21 Cilia and Flagella Structure: Function: Slender and hair-like
Ex. Tail on sperm Function: Move liquid Move cell

22 endoplasmic reticulum
nucleus protein on its way! DNA TO: RNA vesicle TO: TO: vesicle ribosomes TO: protein finished protein Golgi apparatus Making Proteins

23 Our organelles do all those jobs!
Cell Summary Cells have 3 main jobs make energy need food + O2 cellular respiration & photosynthesis need to remove wastes make proteins need instructions from DNA need to chain together amino acids & “finish” & “ship” the protein make more cells need to copy DNA & divide it up to daughter cells Our organelles do all those jobs!

24 Selling Cells! You and your partner will be assigned an organelle and create an advertisement for it You need to state the function and structure of your organelle as well as creating a slogan for your organelle Be creative!

25 Example Slogans McDonalds Subway Nike I’m lovin it Eat fresh
Just do it

26 Let’s Practice We will brain storm ideas for the cell membrane
No one can use the cell membrane for their organelle later

27 What is the structure of the Cell Membrane?
Lipid bilayer What is the function of the Cell Membrane? Regulates what can go in or out of the cell What are some possible slogans for this organelle?

28 Selling Cells You and your partner will BOTH need to create a plan on pg. 20 of your journals that shows most of the criteria on your directions sheet Once you show me your plan on pg. 20, I will give you the brochure paper to create your actual advertisement Be creative! This is due at the end of class. When you are done, you can get on Achieve 3000
