803/30/12 Cell City pg 229
- Sponge P. 64 65 1. Why do plant cells have a
cell wall and chloroplast and animal cells do
not? - They have a cell wall and chloroplast because
they cant move to escape the weather and find
food. - 2. Why is the vacuole of a plant cell so much
larger than an animal cell? - Plant cells have to store water because they
cant go find water.

1204/09/12 Gummy Bear Lab pg 231
- Sponge 1. How are the doors and windows of a
classroom similar to a cell membrane? - A cell membrane controls what goes in and out of
cell like the doors and windows controls what
comes in and out of the classroom. - 2. If more of a needed material is outside a cell
than inside a cell, which direction will the
substance move? Why? - It will move inside the cell because it will move
from high to low concentration. -
13Gummy Bear Hypothesis
- If we put a gummy bear in water over night it
will get bigger or smaller because like a cell it
is semi-permeable and will allow water to move
into the cell during a process called osmosis.
Osmosis is like diffusion, which occurs when a
substance moves from an area of high
concentration to an area of low concentration.
1404/10/12 Gummy Bear Lab 2 pg 233
- Sponge P. 84 1. Would driving a car be a form
of passive or active transport? Explain. - Active transport, because driving a car requires
energy. - 2. Would flying a glider be a form of passive or
active transport? Explain. - Passive transport, because it doesnt require
energy.

mirrors. - Nosepiece - Holds the objective lenses rotates
to use different lenses. - Middle Objective - Objective with power of 10x
- Low Objective - Objective with power of 4x
(Smallest objective) - High Objective - Objective with power of 40x
(Longest objective) - Stage Clips - Holds the slide in place
- Iris Diaphragm - Controls how much light shines
through - Lamp - Provides the light that shines through the
slide - Eyepiece - The part you look through - also has a
10x lens in it - Arm - Supports the body tube and makes a good
handle for carrying the microscope - Stage - The place where you set the slide

under low power, moves the stage up and down, too - Fine Adjustment Knob - Used for high-power
focusing - Base - Supports the weight of the microscope

microscope. - Heres what a letter e from a newspaper might
look like on a prepared slide. Use this image to
help you answer the following questions. - Write a Hypothesis on your paper about what you
think will happen once you look at the letter e
through the microscope - We know that microscopes will make images appear
larger. What else do you think will happen to
the image of the letter e when looked at
through the microscope?
58- Data and Conclusions
- Using the COARSE adjustment knob with the
microscope on LOW power, raise the stage until
the e can be seen clearly. Draw what you see
below in the LOW POWER circle. Change the
nosepiece to MED/HIGH Power - youll notice the
e is out of focus. DO NOT TOUCH the Coarse
Adjustment knob, instead use the FINE adjustment
knob to sharpen your picture. Draw what you see
in the MED/HIGH power circle. - Compare what you see through the eyepiece and the
e that you see on the stage. Dont say it looks
biggerlook closely! What happened? Why do you
think this happened? - Looking through the EYEPIECE, move the slide to
the upper right area of the stage. What
direction does the image move through the
eyepiece? - How does the ink appear under the microscope
compared to normal view? - Why do you think a specimen placed under the
microscope has to be thin? - Was your hypothesis from above supported? Why or
why not? - How does the letter e as seen through the
microscope differ from the way an e normally
appears?

699/9/10 Ecosphere Mystery! Page 29
- Objective Explain what happens during the
process of photosynthesis and respiration Bell
work There is no need to add the nutrients
necessary for life. How do the shrimp and algae
survive?
70Graphic Organizer
- Use the following words to fill in the organizer
- Glucose(2) carbon dioxide(2) oxygen(2)
- Water(2) photosynthesis sugar
- Sunlight mitochondria chloroplast
- Energy ATP cellular respiration
71- Photosynthesis occurs inside the chloroplast of
the PLANT cell. It uses the carbon dioxide and
water given off by animals along with sunlight to
create sugar (also known as glucose) for food as
well as oxygen as waste.
72- Cellular Respiration occurs inside the
mitochondria of the ANIMAL and PLANT cells. It
uses the Oxygen and Glucose made by PLANTS to
create Energy (ATP) for daily cell processes and
also creates Carbon Dioxide and Water as waste.
Its a Cycle!...
73The Cycle of Life
- What is the equation for photosynthesis?
- H2O CO2 sunlight gt C6H12O6 O2
- What is the equation for cellular respiration?
- C6H12O6 O2 gt H2O CO2 ENERGY (ATP)
- Theyre backwards of one another!!!
74Is there life on other planets?
- You are a crew-member on a space ship that is on
an exploration mission searching for life on
other planets. The commander of the ship has sent
you and three of your crewmates to the surface of
a newly discovered planet. Your mission is to
solve a mystery. You must find out what gas the
other life forms exhale. Your only clue is a CD
video clip of one of the other life forms
exhaling through a straw into a clear container
labeled bromothymol blue. At the beginning of
the video clip the solution inside the
bromothymol blue container is yellow however,
after the other life form exhales into the
container for a period of time the bromothymol
blue solution turns from yellow to blue. - The atmosphere of this new planet is 21 oxygen
and does not contain any known toxins so your
commander sends you to the surface without a
space suit. You and your team are equipped with a
solution of bromothymol blue, safety glasses
(four pairs), a clear container, a straw and a
plastic bag containing water and a sprig of an
aquatic plant. Each member of your team has been
assigned one of the following roles
documentation officer, timekeeper, peacekeeper,
or materials manager. You have 25 minutes from
the time of your arrival on the new planet to
solve the mystery and ready yourself to return to
your ship.
75How do we do this?
- Here are some questions to ask yourself as you
work - 1. What color does the bromothymol blue solution
turn in the presence of carbonate water? - 2. What color does the bromothymol blue solution
turn after you exhale into it for approximately
two minutes? - 3. What do you think would happen if you put the
aquatic plant into the bromothymol blue solution? - 4. What gas (or gases) can bromothymol blue serve
as an indicator for?
76Need more help?
- 5. What gas do you exhale?
- 6. What gas do plants give off?
- 7. How long (in seconds) did you have to exhale
into the bromothymol blue solution to elicit a
color change?
77Is there life on other planets?
- What type of gas does the alien life form
breathe? - How do you know? Explain, using evidence from
your experiment.
