Test Description: The Cell in its Environment
Instructions: Answer all questions to get your test result.
1) The process by which water moves across a selectively permeable membrane is
A
diffusion
B
active transport
C
osmosis
D
passive transport
2) Molecules move by diffusion from
A
an area of low concentration to area of high
B
big things to little ones
C
an area of high to an area of low concentration
D
inside to outside the cell
3) The organelle most important to movement in and out of the cell is
A
the vacuole
B
the cell wall
C
the cell membrane
D
the nucleus
4) Diffusion is the process by which small molecules are
A
used for energy
B
made into sugars
C
move across the cell membrane
D
recycled into other organelles
5) Selective permeability means
A
Some things can come in, while others can not
B
Only little tiny things can enter the cell
C
The cell makes glucose
D
That only big things can get in
6) When your egg sat in the salt water, the cells
A
swelled up, because of osmosis
B
Stayed the same, because of diffusion
C
broke up, because of diffusion
D
shrank, because water moved out because of osmosis
7) The movement of materials through a cell membrane without using energy is called
A
active transport
B
passive transport
C
diffusion
D
osmosis
8) The biggest difference between active and passive transport is
A
the cell doesn\'t need a selectively permeable membrane
B
passive transport doesn\'t require any energy, while active transport does
C
Nothing-there is no difference
D
active transport doesn\'t require any energy, while passive transport does
9) One method of active transport requires the cell to use
A
mitochondria as energy boosters
B
an endoplasmic reticulum as a transport vehicle
C
proteins that work as transport vehicles
D
a nucleus to plan the escape
10) Another method of active transport is called
A
engulfing-the cell membrane surrounds the particle and pinches it off
B
resistance-the cell fights off the foreign body
C
osmosis-water comes across the cell membrane
D
Protein synthesis-the cell proteins eat up the paticle
