Download Cell Structure Practice: Vacuole

QUIZ PRACTICE
The main job of vacuoles is to store
materials.
Since cells require energy, they must store glucose in their
vacuoles.
Since cells make protein, they must store
in their vacuoles.
amino acids
Although they lack an internal skeleton , plants can stand
upright because of the water pressure in the central
vacuole
of their cells.
X
Plants
wilt
because the central vacuole shrinks
due to lack of water
.
Some uni cellular protists have contractile vacuoles, which
enable them get rid of extra water .
State the name of the cell structure shown below.
Cytoskeleton
The cytoskeleton is actually a network of very fine protein
.
fibers
The protein fibers of the cytoskeleton can contract , allowing
some cells to move ; for example, heart muscle cells.
Identify the organelle circled below.
Smooth ER
Explain why it is called smooth ER.
No attached ribosomes
The first job of smooth ER is to build new cell membrane by
putting lipids together. This is especially important when a
cell grows .
The second job of smooth ER is to detoxify harmful
substances such as drugs and alcohol.
State which of these cells (A, B, or C) has a cell membrane.
ALL cells have a cell membrane!
Explain why all cells have a cell membrane.
Because all cells must control what enters/leaves
Describe the structure of the cell membrane.
Lipid
Bilayer
Differentiate between cell structures A and B.
B: cell membrane
A: cell wall
A
B
Describe the function of the cell wall
Provide structure
(In case C.V. shrinks)
A
B
Explain how the cell wall is different from the cell membrane
in terms of what substance they are made from.
Cell membrane: lipids
Cell wall: cellulose
A
B
Explain how the cell wall is different from the cell membrane
in terms of their functions.
Cell membrane: controls what enters/leaves
Cell wall: provides structure
A
B
Explain why the cell wall is unable to control what
enters/leaves the cell.
Cell wall has pores
Anything can enter/leave
A
B
Identify three things plant cells have that animals cells do
NOT have.
I (chloroplast)
G (central vacuole)
J (cell wall)
