A cell was placed in a solution with a 50% salt concentration. The cell has a 3% salt concentration. Check all that are true:
Water will move from the cell to the solution
Water will move from the solution to the cell
The cell was placed in a hypotonic solution
The cell was placed in a hypertonic solution
A root hair tip cell is isotonic with a solution that has a 0.05% salt concentration. Which solution would cause the cell to be in a hypotonic solution?
0.9%
0.02%
10%
1.05%
A hypotonic solution would cause a red blood cell to
Swell and potentially burst
Shrivel up
Stay the same size
The plasma membrane's primary component is the phospholipid bilayer. Because of this, there are small openings between the phosphate heads. What implications does this have?
Large molecules have no way of passing through the plasma membrane.
Small molecules have no way of passing through the plasma membrane.
Water molecules have no way of passing through the plasma membrane.
Small molecules can slip through the openings easier than larger molecules can and will more readily pass through the membrane.
Which of the following are true about active transport?
Molecules move from a high to low concentration
Molecules move from a low to high concentration
Molecules move against their concentration gradient
Molecules move with/along their concentration gradient
Which of the following is true?
Passive transport requires energy
Active transport requires energy
Endocytosis does not require energy
Facilitated diffusion requires energy
Select all that are true
Active transport moves molecules from an area of low to high concentration using energy
Passive transport moves molecules from an area of low to high concentration using energy
Passive transport moves molecules from an area of high to low concentration using energy
Passive transport moves molecules from an area of high to low concentration without using energy
The various components of the plasma membrane include phospholipids, proteins, carbohydrate chains, and cholesterol molecules. All of these things come together to allow certain things in and keeps others out. What vocab term do we associate with this property?
Selective permeability
Concentration gradient
Facilitated diffusion
phospholipid permeability
Water will move..
From the left side to the right side
From the right side to the left side
Back and forth between both at an equal rate
Water always moves towards which solution
The hypertonic solution. More solute means less water and water moves from a high to low WATER concentration.
The hypotonic solution. More solute means less water and water moves from a high to low WATER concentration.
The hypertonic solution. More solute means more water and water moves from a high to low WATER concentration.
The isotonic solution. More solute means more water and water moves from a high to low WATER concentration.
In the scenario above, water will move where?
From the dialysis tubing to the beaker
From the beaker to the tubing
Back and forth between the two at the same rate
The dialysis tubing is _____________ to the beaker which is _________________
Hypotonic, hypertonic
isotonic, isotonic
Hypertonic, hypotonic
Which of the scenarios represents active transport?
A
B
C
D
Glucose is a large molecules and therefore needs assistance passing through the cell membrane. What is the most likely type of transport?
A - simple diffusion - no energy needed
B - simple diffusion - no energy needed
A - Facilitated Diffusion - no energy needed
B - Facilitated diffusion - no energy needed
Select all that A and B have in common
Both are types of passive transport
Both are moving molecules down their concentration gradient
Both are moving molecules through the phospholipid bilayer
Both require no energy
Select the examples of passive transport
Osmosis
Facilitated Diffusion
Na/K pump
Endocytosis
