Chapter 7 Test
Instructions:
• The test is in the same style as a visual quiz. However, you
get to work at your own pace.
• You can discuss each answer with your table partner.
• Together, you will turn in one set of answers.
• Discuss each answer before writing!
• During the discussion, decide which concepts from the
notes to include in your answer.
• Remember to underline each concept.
• If you can’t whisper, you will work alone.
Good luck, and remember to whisper
when discussing your answers!
1. For the diagram below:
a. Identify the types of cells shown below
b. List 3 ways that cells A and B are different
Cell A
Cell B
2. Explain why both cells contain DNA and ribosomes.
Cell A
Cell B
3. Explain why the organelles of a eukaryotic cell are
membrane-bound.
4. “Extremophile” bacteria are prokaryotes that live in
extreme environments, such as volcanic vents. Explain why
these bacteria can survive where most eukaryotes cannot.
eukaryotes:
5. In theBOTH
cellsprokaryotes
below, no and
nucleus
is visible. List two other

pieces of evidence
to support
fact that these are
Prokaryotes and Eukaryotes
– Contain DNA
eukaryotic cells.
– Make and secrete protein
6. Identify the cell below as animal, plant, fungus, protist, or
bacteria, and defend your answer.
7. For the diagram below:

11. Below is a micrograph of a heart muscle cell. Explain why
this cell contains an abundance of mitochondria.
12. When you eat bread, your cells transform the starch into
energy. Identify the organelles involved, and the processes
they perform.
13. Plant cells contain chloroplasts and are able to perform
photosynthesis. Explain why plants still need mitochondria.
14. Explain why plants wilt when they are not watered.
15. Identify the organelle circled below, and describe its
function in unicellular protists.
16. The liver is an organ that helps the body get rid of toxins.
Identify an organelle that is abundant in liver cells, and
defend your answer.
17. Explain why ALL cells – even bacteria – are surrounded by
cell membranes.
18. Describe the structure of the cell membrane.
19. For the diagram below:
a. Identify structures A and B
b. Explain why A is not as flexible as B
A
B
20. Explain why structure A, despite its strength, is unable to
control what enters/leaves the cell.
A
B
21. Identify the substance labeled “extracellular fluid” in the
diagram, and explain how it is different from pure water.
The diagram below shows the concentrations of a dissolved
solute, carbon dioxide gas (CO2), inside and outside of a cell.
= CO2
22. State whether the cell will use simple diffusion, facilitated
diffusion, or active transport to move CO2 into the cytoplasm,
and defend your answer with TWO reasons.
= CO2
23. Predict whether or not the cell will have to use energy to
transport CO2 into the cytoplasm, and defend your answer.
= CO2
24. Explain why this cell – and all cells – must transport
solutes across their cell membranes.
= CO2
