Quiz Chapter 7-Tour of the Cell

1. Which organelle out of the following is found in both plants and
animal cells?
a. chitin
b. mitochondria
c. cell wall of cellulose
d. tonoplast
e. centrioles

2. Describe the ways/methods that cilia and flagella use to bend.

3. If you were studying the detailed structure of an organelle in the
cytoplasm of a human liver cell, what type of microscope would you use
and why?

4. Centrioles are normally present in:
a. cytoplasm of bean cells
b. cytoplasm of cheek cells
c. cytoplasm of onion cells
d. nuclei of liver cells
e. nuclei of bean cells

5. Intracellular transport of materials is most closely associated
with which of the following organelles?
a. cell wall
b. ribosome
c. cell membrane
d. endoplasmic reticulum
e. Golgi apparatus

6. Which organelle is found in prokaryotic cells?
a. ribosome
b. Golgi apparatus
c. Rough ER
d. Smooth ER
e. membrane-bound nucleus

7. The destruction of which of the following would most cripple a
cell’s ability to undergo cell division?
a. microfilaments
b. intermediate filaments
c. microtubules
d. actin fibers
e. keratin fibers

ANSWERS:

1. b
2. In cilia and flagella, ATP powers Dynein arms to move neighboring
doubles of microtubules, but because they are anchored within the
organelle, the doubles bend instead of sliding past each other.
3. A transmission electron microscope – a SEC only lets you study the
surface of cells, while a TEC lets you view organelles within the
cells.
4. b
5. d (?) I wasn’t sure between the difference of intra/inter, but I
believe intercellular transport is between two different cells, so
would use a cell membrane, but intracellular is transport within the
cell itself. But correct me if I’m wrong
6. a
7. c
