20. Review – Time to collect!
1. Add color
2. Read through events
3. Cut out and align
4. Glue in place (more than one paper is okay.

23. Be sure to WRITE
The following SHOULD have been written yesterday, but be sure. It WILL be on a test (like Thursday of next week!!)

24. Francesco Redi – (1668)
People believed flies spontaneously came from meat… “Spontaneous Generation”
Redi covered one flask, left one open to air.
Observed flies laying eggs on meat.
Flies come from flies. Life comes from life.

25. All of these statements create the Cell Theory!
Francesco Redi (1668)
Life comes from life.
Schleiden (1838)
Plants are made of cells…cells are basic building block of all plants.
Schwann (1839)
Animals are made of cells…cells are basic building block of all living things.
Virchow (1850)
Cells come from other living cells.
All of these statements create the Cell Theory!

26. Anton van Leeuvenhoek (1670)
Robert Hooke (1665)
Used a COMPOUND microscope
Saw cork (dead plant cells)
Described the cell walls (boxes) as “CELLS”
Anton van Leeuvenhoek (1670)
Looked at pond water…living cells
Described the moving beings as “animal-cules”

27. Review Compound Microscope 1. Eye Piece – lens closest to the eye.
2. Body Tube – gives distance between eyepiece and objective.
3. Nose Piece – holds the objectives.
4. Arm – holds the tube and lenses.
5. Objective lenses –
lens closest to the slide.
6. Stage – platform for the slides.
7. Stage clips –
Holds the slide in place.
8. Coarse Adjustment knob –
Moves stage up/down (to focus).
9. Diaphragm / IRIS –
Controls the amount of light.
10. Fine Adjustment knob –
Moves stage up/down slightly
11. Light –
Shines light through the slide, lens, tube.
12. Base – Holds up the entire microscope.

28. Cells and their Organelles
ER = Endoplasmic reticulum
Check your
work
14. How does rough ER differ from smooth ER?
15. Rough ER is connected to the _______________________ and to the ____________________ ER.
Rough has ribosomes (making it rough or bumpy). Smooth does not have ribosomes.
Outer nuclear membrane
smooth

29. Cells and their Organelles
Endoplasmic reticulum
16. Proteins made by rough ER travel to the Golgi in sacks called _____________. Golgi ____________ and ___________ proteins for export out of the cell.
Give three jobs of the ER. A. B. C.
Vesicles
modifies
packages
Makes proteins and lipids
Controls calcium levels in muscles
Detoxifies poisons, alcohol, drugs.

30. Cells and their organelles
18. What process takes place inside chloroplasts? 19. What is the energy for this process? 20. What pigment traps the energy?
Photosynthesis – food energy from light energy
The light energy is typically the sun.
Chlorophyll (green) helps to change light energy into food energy.
