What is the difference between hypertonic, hypotonic, and isotonic solutions?
- A hypotonic solution is less concentrated than the cell, a hypertonic solution is more concentrated than the cell, and isotonic is balanced between the cell and outside solution. Our cells are surrounded by a semi-permeable membrane that allows certain things to move in and out.
What is the effect of hypotonic, isotonic and hypertonic solutions on cell membranes?
- A hypotonic solution is less concentrated than the cell, a hypertonic solution is more concentrated than the cell, and isotonic is balanced between the cell and outside solution. Our cells are surrounded by a semi-permeable membrane that allows certain things to move in and out.
What are the benefits of hypotonic drinks?
- Hypotonic drinks will also give you a speedy top-up of electrolytes – those vital salts and minerals lost in sweat – to help regulate muscle function and keep your fluid levels balanced. What are the disadvantages of hypotonic drinks?
What happens when cells are placed in a hypertonic solution?
- A hypotonic solution has less solute concentration and more solvent concentration. When a cell is placed in hypotonic solution , water enters the cell through osmosis. Animal cells swell and burst due to absence of cell wall. This happens when a cell shrinks inside its cell wall while the cell wall remains intact.

Cell Membrane & Tonicity Worksheet
Composition of the Cell Membrane & Functions
The cell membrane is also called the PLASMA membrane and is made of a phospholipid BI-LAYER. The phospholipids have a hydrophilic (water attracting) HEADS and two hydrophobic (water repelling) TAILS. The head of a phospholipid is made of an alcohol and GLYCEROL group, while the tails are chains of FATTY ACIDS. Phospholipids can move SIDEWAYS and allow water and other NON-POLAR molecules to pass through into or out of the cell. This is known as simple PASSIVE TRANSPORT because it does not require ENERGY and the water or molecules are moving WITH the concentration gradient.SKETCH AND LABEL a
phospholipid coloring the heads red and the tails blue. Another type of lipid in the cell membrane is CHOLESTEROL that makes the membrane more fluid.Embedded in the phospholipid bilayer are PROTEINS that also aid in diffusion and in cell recognition.
Proteins called INTEGRAL proteins go all the way through the bilayer, while PERIPHERAL proteins are only
on one side. Large molecules like PROTEINS or carbohydrates use proteins to help move across cellmembranes. Some of the membrane proteins have carbohydrate PARTS attached to help cells in recognize
each other and certain molecules.List 4 functions of the cell or plasma membrane:
a. CELL SIGNALING b. SELECTIVE TRANSPORT c. EXCRETION OF WASTES d. STRUCTURAL SUPPORT Correctly color code and identify the name for each part of the cell membrane.Letter Name/Color Letter Name/Color

THE MOVEMENT OF WATER ACROSS A SELECTIVELY PERMEABLE MEMBRANE FROM AN AREA OF HIGH CONCENTRATION TO AN AREA OF LOW CONCENTRATION. In which direction does water move across membranes, up or down the concentration gradient? DOWNDefine these 3 terms:
a. isotonic- THE CONCENTRATION OF DISSOLVED PARTICLES ARE THE SAME INSIDE AND OUTSIDE THE CELL Ȃ THERE IS NO OVERALL CHANGE IN THE CELL SIZE b. hypertonic THE CONCENTRATION OF DISSOLVED PARTICLES ARE HIGHER OUTSIDE THE CELL THAN INSIDE THE CELLȂ WATER WILL LEAVE THE CELL IN AN ATTEMPT TO DILUTE THE OUTSIDECONCENTRATION
c. hypotonic THE CONCENTRATION OF DISSOLVED PARTICLES ARE LOWER OUTSIDE THE CELL THAN INSIDE THE CELLȂ WATER WILL ENTER THE CELL IN AN ATTEMPT TO DILUTE THE INSIDECONCENTRATION
Use arrows to show the direction of water movement into or out of each cell. Color and label the cell in an
isotonic environment light blue, the hypotonic environment yellow, and the hypertonic environment light
green. Match the description or picture with the osmotic condition: A. Isotonic __ C __ solution with a lower solute concentration __A __ solution in which the solute concentration is the same B. Hypertonic __ A__ condition plant cells require __ A__ condition that animal cells require C. Hypotonic __ C __ red blood cell bursts (cytolysis) __ C ___ plant cell loses turgor pressure (Plasmolysis) __ B ___ solution with a higher solute concentration __ A __ plant cell with good turgor pressure __ C___ solution with a high water concentration Label the tonicity for each solution (isotonic, hypotonic, or hypertonic):HYPOTONIC ISOTONIC HYPERTONIC HYPOTONIG ISOTONIC HYPERTONIC
3Transport Requiring Energy
What type of transport is represented by the following picture? ACTIVEWhat energy is being used? ATP
In which direction (concentration gradient), is the movement occurring? AGAINST Color the internal environment of the cell yellow. Color and Label the transport proteins red and the substance being moved blue. One type of active transport is called the SODIUM- POTASSIUM pump which helps muscle cells contract. This pump uses PROTEINS to move ions AGAINST the concentration gradient. The protein that is used to pump the ions through is called a TRANSMEMBRANE (INTEGRAL) protein and it changes its SHAPE to move the ions across the cell membrane. Label and color the carrier proteins red and the ions green.TONICITY AND OSMOSIS
Part I Ȃ Fill in the blanks.
A SOLVENT is a fluid in which a substance is dissolved.A SOLUTE is a substance dissolved in a solvent.
A SOLUTION is a combination of solute and solvent. The process by which water diffuses across a membrane called OSMOSIS Part II Ȃ Look at the solutions illustrated above and fill in the blanks.1. Solution B is HYPERTONIC to Solution A. This is because Solution B has a greater concentration of
SOLUTES in it than does Solution A. Solution C has no solutes dissolved in it, therefore it is HYPOTONIC to
both Solutions A and B. 42. As a relative concentration of solutes in two solutions increases, of necessity the concentration of water in
the same two solutions INCREASES. Solution A has a lower concentration of SOLUTE than does Solution C;
Solution A is also hypertonic to Solution C.
3. If you wanted to make Solution A isotonic to Solution B, you could add water to Solution B or you could
add solute to Solution A. If you took all three solutions, put them into a large container and mixed them
thoroughly, then redistributed the solution among three containers, Solution A would be ISOTONIC to Solution B. Solution A would also be ISOTONIC to Solution C, and Solution C would be ISOTONIC toSolution B.
Part III Ȃ Look at the solutions and cells illustrated above and fill in the blanks.1. Because the cytoplasms of the plant and the animal cell have equal concentrations of solutes, we can say
their cytoplasms are ISOTONIC to each other. If we put both the plant and the animal cells into Solution A,
we would expect no change in the cells, because Solution A is ISOTONIC to the cytoplasm of each cell.
would expect water to LEAVE the cells through the process of OSMOSIS. This would result in the cytoplasm
of both cells shrinking.HYPOTONIC to the cytoplasm of both cells. WATER will enter both cells through osmosis. The animal cell is
likely to BURST, unfortunately. The plant cell, however, is protected from this because of the presence of its
CELL WALL.
Refer to the U-tube pictures above when answering the questions below.1. Why did the number of water molecules on each side of the membrane change, whereas the number of
sugar molecules stayed the same? WATER MOLECULES ARE SMALL ENOUGH TO PASS THROUGH THE PORES OF THE MEMBRANE, HOWEVER, THE SUGAR MOLECULES ARE NOT.2. How does the plasma membrane of a cell compare with the membrane in the U-shaped tube?
THEY ARE BOTH SELECTIVELY PERMEABLE BASED ON SIZE OF PARTICLES 53. Explain the behavior of water molecules in the isotonic solution. WATER MOLECULES WILL MOVE INTO
AND OUT OF THE CELL CONTINUOUSLY, HOWEVER, THERE WILL BE NO OVERALL CONCENTRATIONCHANGE SINCE THE MOVEMENT SHOULD BE EQUAL.
4. Does osmosis occur if a cell is placed in an isotonic solution? NO, BECAUSE THERE IS NO
CONCENTRATION GRADIENT (AREA OF HIGH TO AREA OF LOW Ȃ ISOTONIC IMPLIES EQUALCONCENTRATIONS)
5. Why does water enter a cell that is placed in a hypotonic solution? BECAUSE THE CONCENTRATION OF
SOLUTE IS LOWER OUTSIDE THE CELL THAN IT IS INSIDE THE CELL, SO THE WATER ENTERS THE CELL TO TRY TO DECREASE/EQUALIZE THE CONCENTRATIONS ON BOTH SIDES OF THE MEMBRANE.6. What happens to the pressure inside a cell that is placed in a hypertonic solution? THE PRESSURE
DECREASES AS THE WATER LEAVES THE CELL.
7. What can happen to animal cells when placed in a hypotonic solution? Explain. ANIMAL CELLS IN
HYPOTONIC SOLUTIONS CAN RUPTURE AS MORE AND MORE WATER RUSHES INTO THE CELL. PLANT CELLS WILL NOT HAVE THIS ISSUE BECAUSE THE CELL WALL PROTECTS THE PLANT CELLS FROMRUPTURING.
8. What causes a plant to wilt? PLANTS PLACED IN A HYPERTONIC SOLUTION WILL WILT AS WATER IS
REMOVED FROM THEM RESULTING IN PLASMOLYSIS.
