UNIT 4 TEST REVIEW
STEP ONE
1.) Log onto Edmodo.com
2.) Click on the “Spring 2014 Biology” Group
3.) In the Group Post Section click on Take the Unit 5 Review Quiz
STEP TWO
4.) Click on “Folders”
5.) Click on “Links to Helpful Websites”
6.) Click on “ClassZone – Biology 2008
STEP THREE
1.) In the top left corner click the gray dropbox that says “ chapter home…”
2.) Scroll down until you see Ch. 4: Cells and Energy. Click it
3.) Click on the underlined blue “Interactive Review” link located under the green
“Interactive Review” Tab
STEP FOUR
1.) Begin by clicking on the “Key Concepts” Tab located at the top of the screen.
2.) In your own words, summarize the Key Concepts for sections 4.2 and 4.3 on
your separate piece of paper. (You will have to click on the green section tabs to
change sections).
STEP FIVE
4.) Next, click on the “Concept Maps” Tab at the top of the screen
a. Complete the concept maps for sections 4.2 and 4.3
b. On your separate sheet of paper, you must draw both concept maps that
you complete on the website.
STEP SIX
1.) Next, click on the “Quizzes” Tab at the top of the screen
1.) Complete section quizzes 4.2 and 4.3
2.) **For EACH quiz, you are to rewrite EACH question that you miss on the quiz
AND the correct answer on your separate sheet of paper.
For example: From Section 4.1 Quiz – Question #1
You would write: How is energy released from an ATP molecule?
You would then write the answer: By removing the third phosphate group
from ATP

READ
Photosynthesis is the process in which plants use light energy, water, and carbon
dioxide to produce food. Plants use the food they make for growth and for carrying out
other life processes. Sunlight is the natural energy source for photosynthesis. White
light form the sun is a mixture of all colors of the light spectrum: red, orange, yellow,
green, blue, violet. Light can be either absorbed or reflected by substances called
pigments. Most plants are green because the pigment chlorophyll reflects green and
yellow light and absorbs the other colors of the spectrum.
***In this virtual lab you will perform an experiment to investigate what colors of
the light spectrum cause the most plant growth. Calculate the plant growth by
measuring the height of each plant under different colors of light. Compare these
measurements and interpret a graph to determine which colors of the spectrum
cause the most plant growth.
Follow the steps below:
1.)
Click on the Video button. Watch the animation to learn about how
light affects photosynthesis.
2.)
Make a hypothesis about which part of the light spectrum causes
the most plant growth and which part of the spectrum causes the
least plant growth. Record your hypothesis on your sheet of
paper.
3.)
Test your hypothesis by choosing different plant seeds and
observing how the plants grown under different colors of light
4.)
Choose the type of seed that you want to test and click its seed
packet.
5.)
Click the arrows on the color display to select a color light filter for
each set of three plants
6.)
Start the experiment by clicking the light switch to the ON position
7.)
Observe the plant growth
8.)
Click the ruler and drag it to each plant to measure the height. Use
the calculator to average the heights of the three plants under each
color light filter.
9.)
YOU MUST REDRAW THE TABLE THAT YOU SEE WHEN YOU
CLICK ON TABLE/GRAPH ON YOUR SEPARATE SHEET OF
PAPER. Record your calculations in the table.
10.)
Click the Reset button. Repeat the experiment using a different
color light filter and the same type of seed. Click Graph to see the
results of your experiment.
11.)
After all color filters have been tested on one type of seed, conduct
the experiment again with another type of seed to verify your
conclusions.
12.)
Does your data support your hypothesis? On your separate sheet
of paper explain why or why not. Use the data from the
experiment to explain.
