1. List the 9 organelles we studied, their functions, and your analogy from
your cell project.
Nucleus-the control center with DNA-manager
Cytoplasm-surrounds and supports organelles-chairs and tables
Ribosomes-make protein (cell product)-chef
Endoplasmic reticulum-moves substances in cell-wait staff
Mitochondria-breaks down food to make energy-ovens
Vacuole-stores water, etc.-refrigerator
Chloroplast-uses sunlight to make glucose (sugar)-generator
Cell membrane-protects cell, keeps organelles in, bad stuff out-doors
Cell wall-protects plant cells, fibrous-walls
Cell 1=plant
cell 2=bacteria
2. On the above pictures:
a. Write out the organelles for the following labels
A cell wall
E cytoplasm
B vacuole
F ribosomes
C chloroplast
G endoplasmic reticulum
D cell membrane
H mitochondria
I nucleus
b. Label each cell (plant, animal, bacterium)
See above
cell 3=animal
Answer all the possible essay questions completely:
3. How do you calculate the magnification when viewing an object under a microscope?
Ocular lens=10, objective lenses = red=4, yellow=10, blue=40
Multiply ocular lens magnification x objective lens magnification
4. Write the steps for making a wet mount slide.
Obtain a slide and a cover slip. Put the specimen on the slide and add a drop of water. Place
the cover slip at 45 degree angle and gently place it over the specimen.
5. What organelles do plant cells have that animal cells do not?
Chloroplast and cell wall
6. Both animal and plant cells contain vacuoles, why do plant cells have a single large vacuole
while animal cells do not?
It supports plants so they can stand up firmly
7. Compare and contrast the procedure for viewing a specimen under low power vs. high power.
Use coarse focus knobs to focus your specimen. On high power we use the fine focus knobs.
8. If you change from medium power to high power and your specimen disappears, what step
MUST you take to see your specimen again?
1. Go back to medium power and focus again.
2. Adjust the slide.
a. What at least two possible reasons your specimen was “lost?”
1. You could be looking at white space.
2. Your slide could be in the wrong place.
3. Your slide may need adjusting with focus knobs.
