Cellular Energy Bellringer #5
Complete the following Venn Diagram to compare
and contrast mitochondria and chloroplasts. And
YES, it MUST be a Venn Diagram!!!
10/1—Binder Time
• Clear your desk of everything EXCEPT
your Science Binder.
• As your assignments are being handed back
to you, place them in the correct section of
your binder.
• HOLE-PUNCH them & put them in the rings,
NOT THE POCKETS!
• Order: Chronological per section.
▫ Example: BR section, first paper should be
the August bellringers, last should be the
October bellringers.
Cellular Energy Bellringer #6
Look at the graph to the
left. It shows two plants;
one exposed to low light,
and one exposed to
moderate light, and the
amount of chlorophyll
produced.
Which of the two
lighting conditions
would you want to
expose plants to in
order to maximize
photosynthesis?
Explain your answer.
Cellular Energy Bellringer #7

One of the products of photosynthesis is glucose
(C6H12O6). Which of the following statements about
glucose is FALSE?
1. Plants use the energy from glucose to convert nutrients
to body tissues and grow larger.
2. Glucose is used to create a variety of plant products.
3. Glucose that is not immediately used by the plant is
stored for later use.
4. Glucose that is not immediately used by the plant is lost
as waste material.
