plant cells are in a hypertonic solution & the cells shrink

Why is misting fruits and vegetables with water help them look fresh?

vacuoles fill with water due to osmosis

Which of the following is a function of the plasma membrane?

regulate the movement of material in & out of cell

During diffusion, when the concentration of molecules on both side of the membrane are the same

they will continue to move in both directions

What is a major difference between facilitated diffusion and active transport?

active transport moves substances from low to high

When is dynamic equilibrium reached?

when there is continuous movement, but no change

diffusion of water across the cell membrane

Questions 21

Answers

1
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
solutes to move into the cell
solutes to move out of the cell
water to move into the cell
water to move out of the cell
2
Why do plants wilt?
plant cells are in a hypotonic solution & the cells swell
plant cells are in a hypertonic solution & the cells shrink
the plant cells are sleepy
plants don't wilt they get lazy
3
Which means of particle transport requires no energy?
sodium/potassium pump
osmosis
endocytosis
exocytosis
4
The diffusion of water across a selectively permeable membrane is called
active transport
pinocytosis
osmotic pressure
osmosis
5
Which term describes the relatively constant internal physical condition of an organism?
organ system
cell specialization
unicellularity
homeostasis
6
Solution C is considered
hypotonic
isotonic
hypertonic
active transport
7
A plant cell is placed in a hypotonic solution. What will happen to the plant cell?
it will enlarge
it will stay the same
it will wilt
it will shrink
8
What types of materials are expelled from cells during exocytosis?
large molecules like hormones
charged ions
water and glycerol
small molecules such as carbon dioxide
9
Which of the following structures serves as the cell's boundary?
channel protein
plasma membrane
mitochondria
chloroplast
10
Which of the following is an example of passive transport?
facilitated diffusion
sodium/potassium pump
endocytosis
exocytosis
11
Solution B is considered
active transport
hypotonic
isotonic
hypertonic
12
Why is misting fruits and vegetables with water help them look fresh?
vacuoles fill with water due to osmosis
plant cells in a hypotonic solution lose water
water cannot move through the cell membrane
plants do not have a rigid cell wall
13
Which of the following is a function of the plasma membrane?
break down lipids, carbs, and proteins
regulate the movement of material in & out of cell
store water, salt, proteins, and carbs
keep the cell wall in place
14
Algae cells are placed in an isotonic solution. Salt is added to the solution, what will happen
they will burst
They will swell
stay the same
shrink
15
Which movement of substances through a cell membrane requires energy?
facilitated diffusion
osmosis
active transport
diffusion
16
Solution A is considered
active transport
hypertonic
hypotonic
isotonic
17
During diffusion, when the concentration of molecules on both side of the membrane are the same
they will move into the cell
they will stop moving
they will continue to move in both directions
they will move out of the cell
18
What is a major difference between facilitated diffusion and active transport?
active transport uses proteins
active transport moves substances from low to high
facilitated diffusion moves molecules through the membrane
facilitated diffusion requires energy
19
When is dynamic equilibrium reached?
when the movement of molecules stops being random
when the rate of change in the solution slows by one half
when there is continuous movement, but no change
when the molecules are mixed and stop moving
20
What is osmosis?
diffusion of glucose across the cell membrane
diffusion of water across the cell membrane
there is no such thing as osmosis
sleeping on a textbook and acquiring knowledge
21
If a cell with 60% solute, is placed in a solution with 10% solute, where will water move?
water would enter and leave in equal amounts
out of the cell causing it to shrink
nothing will move
into the cell causing it to swell
