09/14/12 Cell Study Guide P. 49
  • Sponge P. 96-98 1. Explain what happens during
    the cell cycle.
  • During the cell cycle a cell grows, prepares for
    division, and divides into two daughter cells.
  • 2. Explain the difference between interphase and
    cytokinesis.
  • During interphase the cell grows and copies DNA,
    while during cytokinesis the cell divides into
    two new cells.

Cell Review
  • 1. osmosis-diffusion of water.
  • 2. diffusion-movement of a substance from high to
    low concentration.
  • 3. semi-permeable membrane- allows certain
    substances to pass through the cell membrane.
  • 4. photosynthesis-plants make food from sunlight.
  • 5. cellular respiration-cell makes energy, ATP.
  • 6. endocytosis-uses energy to move things into
    the cell.
  • 7. exocytosis-uses energy to move things out of
    the cell

3
Cell Review
  • 8. prokaryotic-A cell without a nucleus.
  • 9. eukaryotic-A cell with a nucleus.
  • 10. homeostasis-balance of internal environment.
  • 11. similarities- they both move substances from
    high to low concentration.
  • Differences-osmosis is the diffusion of only
    water.
  • 12. Active transport uses energy to move
    substances, passive does not.
  • 13. chloroplast, foodsugar, oxygen
  • 14. mitochondria, energyATP, carbon dioxide

03/30/12 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.

04/09/12 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.

13
Gummy 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.

14
04/10/12 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.

    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?

9/9/10 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?

70
Graphic 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!...
73
The 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!!!

74
Is 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.

75
How 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?

76
Need 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?

77
Is 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.

78
9/10/10 Youre an Organelle! Page 31

  • Task 1 (You will have 15-20 minutes to complete
    this.)
  • You will be assigned an organelle that you will
    pick out of a basket.
  • Using your textbook (pages 60-67), write a
    sentence answering each of the following
    questions on your notes page. Be sure you
    understand your job as you will have to act the
    part!
  • What is my job in the cell?
  • What do I look like?
  • Where in the cell would you find me?
  • On your construction paper, write the name of
    your organelle and draw a large picture of it.
    Carefully add your string and wear it!

80
Youre an organelle!
