1. PLANT AND ANIMAL CELLS

2. Sit Down Quietly Backpacks by your feet.
Get out your comp notebook, pencil, scissors and glue stick.
Wait until I give you permission to take your backpack to the lab table.

3. Early Scientists’ Contributions: Record notes on pages 2 and 3

4. Anton van Leeuwenhoek
First compound light microscope

5. Robert Hooke
Coined the term “cell”

6. Matthias Schlieden
All plants are made of cells

7. Theodor Schwann
All animals are made of cells

8. Rudolf Virchow
Cells can only arise from pre-existing cells

9. Cell Theory: Record on page 4
All organisms are made up of one or more cells.
The cell is the basic unit of organization of all organisms.
All cells come from other cells all ready in existence.

12. Cell Functions: complete the worksheet in comp notebook.

13. CELL WALL: PLANT Analogy: Like a brick wall
Function: Gives the cell most of its support and structure
A thick, rigid membrane that surrounds a plant cell
Bonds with other cell walls to form the structure of the plant
Analogy: Like a brick wall

14. CELL MEMBRANE Analogy: Like a gate
Function: Semi permeable, allowing some substances to pass into the cell and blocking others.
Thin layer of protein and fat that surrounds the cell
   
Analogy: Like a gate

15. Chloroplast Analogy: I am sweet like a mint gumdrop.
Function: Where photosynthesis takes place
An elongated or disc-shaped organelle containing chlorophyll
Analogy: I am sweet like a mint gumdrop.

16. Cytoplasm Function: Where the organelles are located.
Analogy: Like cherry Jello.
Cytoplasm

17. ENDOPLASMIC RETICULUM
Function: transports materials through the cell
Rough ER is covered with ribosome's that give it a rough appearance
Analogy: Like a train.

18. Golgi Bodies Analogy: Like Amazon
Function: Golgi bodies are the packaging and secreting organelles of the cell.
Are stacks of membrane-covered sacs that package and move proteins to the outside of the cell.
Analogy: Like Amazon

19. Lysosome Analogy: Like a garbage disposal
Function: Where the digestion of cell nutrients takes place
Also called cell vesicles
Spherical organelles surrounded by a membrane
They contain digestive enzymes
Analogy: Like a garbage disposal

20. Mitochondria Analogy: Like a battery
Functions: Powerhouse of the cell. Where energy of the cell is released.
Spherical to rod-shaped organelles with a double membrane
Membrane is infolded many times, forming a series of projections (called cristae)
Analogy: Like a battery

21. Nucleus: The Manager Analogy: Like a boss or CEO
Function: Controls many of the functions of the cell
Spherical body containing many organelles, including the nucleolus
Contains DNA (in chromosomes)
Surrounded by the nuclear membrane
Analogy: Like a boss or CEO

22. Ribosome's
Function: Small structures in the cytoplasm that create proteins.
Ribosome's are either free floating in the cytoplasm of a cell or attached to endoplasmic reticulum in a cell.
Analogy: Like BBQ ribs

23. Vacuole Analogy: Like a suitcase
Function: a vacuole is a temporary storage space for the cell
Fluid-filled, membrane-surrounded cavities inside a cell
Fills with food being digested and waste material that is on its way out of the cell
Analogy: Like a suitcase
