a)
A
b)
B
c)
C
d)
D
6.
Which way will the water molecules move during osmosis?
a)
Out of the cell, so the cell shrinks.
b)
Out of the cell, so the cell swells.
c)
Into the cell, so the cell shrinks.
d)
Into the cell, so the cell swells.
7.

molecules move everywhere
8.
An animal cell placed in a hypertonic (salty) solution will
a)
Stay the same
b)
Shrink- get smaller
c)
Swell- get bigger
9.
What type of cellular transport uses energy?
a)
Passive Transport
b)
Active Transport
10.
Active transport requires energy because...

The cell is moving something against a concentration gradient
b)
The cell is moving something with a concentration gradient
11.
Where will the water go?

Into the cell
b)
Out of the cell
c)
Equally in & out - it's isotonic
d)
There is no water
12.
In the cell pictured, which way would water move?
a)
Into the cell, causing the cell to swell
b)
Out of the cell, causing the cell to shrink
c)
In and out of the cell equally, keeping the shape the same
13.

Plant cell
b)
Animal cell
14.
In which case would a cell most likely shrink?
a)
when placed in a solution containing a high salt concentration
b)
when placed in a isotonic solution

when placed in a solution containing a low pH
d)
when placed in a solution containing distilled water
