1. Daily Question
What do you think the term “organelle” means? Write down your answer in your daily question book.

2. Cell Types
Two major types
Prokaryotic
Eukaryotic

3. Prokaryotic Cells
Has a cell wall and cell membrane but genetic material not surround by a membrane.
Smaller than eukaryotic cells
Must be unicellular
No nucleus = Prokaryotic
EUKS have NUCS, PROS DON’T

4. Eukaryotic Cells
Plants, animals, fungi, and protists are made of one or more cells.
Contain organelles

5. Cell Shape and Movement
Size and shape are part of the function of the cell
A cell is made of different structures that work together and keep the cell alive called organelles.

6. Plant Cells Vs. Animal Cells
Plant Cells have
Cell Wall
Chloroplasts
Plant Cells are square.
Animals Cells do not have
Cell Walls
Animal Cells are round.

7. Cell Membrane
Controls which substances pass in and out of the cell (selectively permeable)
Made of phospholipids and proteins
Found in all cells

8. Cell Wall Found in Lies outside the cell membrane
Plant, fungal, bacterial, and some protists
Lies outside the cell membrane
Rigid, helps support and protect from viruses
Contains cellulose
Color - Gold

9. Cell Appendages Flagella Cilia Assist in movement
Long, hair/tail like organelles that extend from surface of cell
Cilia
Short hairlike structures
Assist in movement

10. Cytoplasm Area between cell membrane and nucleus
Fluid inside the cell made of water, salts and other molecules
Contains organelles
Color - Yellow

11. Cytoskeleton Network of long protein threads located in cytoplasm
Maintains shape and size
Participates in movement

12. Daily Question – 2/21/17
List the differences between a prokaryotic cell and an eukaryotic cell. Give an example of each.
What is the difference between a cell wall and a cell membrane?

13. Cell Organelles
Tiny cell structures that carry out specific functions within the cell.
Produce energy from food, build and transport needed materials, storing information and store and recycle wastes
Can you name any???

14. Nucleus Stores DNA Directs all of the cell’s activities
Nuclear membrane – double membrane surrounding nucleus
Nuclear pores – small holes in nuclear envelope
Nucleolus – where ribosomes are made
Nucleus – Purple; Nucleolus – Pink; Nuclear Membrane - Red

15. Chromatin Are thin strands floating in the nucleus.
Is the genetic material (DNA), or the instructions that direct the functions of the cell.
Color – Bolder (black)

16. Manufacturing Molecules

17. Ribosomes Not surrounded by membrane Assembles protein
Free or Attached to ER

18. Endoplasmic Reticulum
System of membranous tubules and sacs that help molecules move from one part to another
Amount depends on cell activity
Rough - Have ribosomes – where proteins are made
Smooth – Don’t have ribosomes- where lipids are produced

19. Processing Energy

20. Mitochondria Makes ATP – energy molecule in the cell 2 membranes
Smooth outer
Inner membrane
Cristae – increase surface area
Has own DNA

21. Chloroplasts Chloroplasts Membrane bound organelle
Use light to make food (sugar – glucose) from water and CO2
Photosynthesis
Green!

22. Daily Question 3/6/17
1. Draw a picture of either a plant or animal cell.
3. When everyone is done, you are going to exchange papers and label the type of cell and the organelles that are drawn. Do NOT use your notes!
2. In that cell draw at least 5 different organelles.

23. Processing, Transporting, and Storing Molecules
Golgi Body
Vesicles
Lysosomes
Vacuoles

24. Golgi Body Processing, packaging and secreting proteins.
Works with ER; modifies proteins exported by the cell
Exports proteins in vesicles

25. Lysosomes Enclose hydrolytic enzymes w/in a single membrane
Digests proteins, carbs, lipids, DNA, RNA, old organelles
                                                                                

26. Vacuoles Fluid filled organelle
Stores food, water, and waste
Can be LARGE (in a plant) smaller (in an animal).

27. Cell Factory
Inside a Cell - Video

28. Specialized Cells Are found in multi-cellular organisms
The structure of each kind of cell is suited to the unique function it carries out within the organism.
How is a blood cell suited for the job that it does? Nerve Cell?
