osmosis  is the phenomenon in which the two solutions of two different concentrations are separated by the semi permeable membrane. the molecules of the solvent move from their higher concentration to their lower concentration till the concentration of both the solutions becomes equal.

e.g: take a thistle funnel and cover its mouth with a parchment paper. and fill it with concentrated sugar solution. 

place thistle funnel in a beaker containing water and mark the level of sugar solution in the stem of thistle funnel.

leave the apparatus undisturbed for 4-5 hours.

you will observe that the level of sugar solution in the stem rises and the level of water decreases as water passes through the parchment paper into the sugar solutin. it it because of osmosis

A good example of osmosis would be dipping a sponge into water, because there is a higher concentration outside, so the water goes in and makes the sponge expand.

Osmosis is diffusion of water across a semi-permeable membrane.  Salt is too big to pass through a cell membrane, but water molecules can fit.  Since everything wants to reach equilibrium, the only thing that can flow to create equal concentrations is water.

Real world examples of osmosis:

1.  Why we use saline solution for contact lenses - if you ever placed your contacts in pure water you will notice how uncomfortable it is the next day, or if you fail to rinse out your contact case it will get too salty.  Saline solution for contact lenses is the same concentration of salt water as your eye.

2.  Saline drips at the hospital - same ratio of salt water as is in your cells.

3.  Making french fries - more salt makes the french fries more crispy and less soggy.  This is done by pre soaking the potatoes in salt water before frying.

4.  Reverse osmosis - add energy to the system to force the water to flow backwards through a membrane.  It is used as a method to filter or desalinate water (but requires alot of energy)

5.  The different salt ratios in cells explain why salt water fish cannot go in fresh water and vice versa.

Osmosis is the movement of liquid molecules from a higher concentration to a lower concentration through a partially permeable membrane.

An example of osmosis can be the intake of water molecules in plants. As the cell sap of the root hair cell has a more concentrated solution than the soil, water particles moves in the cell through osmosis.

Osmosis is the movement of water molecules from a region of higher water potential i.e. a hypotonic solution to a region of lower water potential i.e a hypertonic solution, against the potential gradient, through a partially permeable membrane.

e.g:- The cellular system of animals/plants, which allows the water molecules and other dissolves substances to pass readily across the partially permeable cell surface membrane in or out from the cytoplasm of the cell. This accounts for

01. turgidity and plasmolysis in plants

02. crenation in animals

 

P.s:- don't confuse osmosis with diffusion for diffusion is the movement of fluid particles from a region of higher concentration to a region of lower concentration (not water potential) against the concentration gradient (not thepotential gradient). Unlike osmosis it is not an obligation to have a membrane. e.g:- evaporation

Osmosis is the movement of something through a membrane from an area of greater concentration to an area of lesser concentration.

An example would be to place two tablespoons of raisins into one cup of water and let sit overnight. The next morning, observe the changes to the raisins. Take them out, keeping as much of the water in the cup as possible. Re-measure the water to see how much the raisins absorbed through osmosis.

Osmosis is a process in which liquid from one solution moves to another solution separated by a semi-permeable membrane. The most common examples of osmosis is provided by all plants and animals. Plant absorb water from the earth through the process of osmosis. Exchange of water in body fluids and body cells in animals (including humans) takes place through osmosis. Arabian countries with limitited supplu of drinking water use the proces of osmosis to generate drinking water from sea water.

Osmosis is the movement of water molecules from the higer particular concentration to the lower particular concentration through a semipermiable membrane.

Eg:The concentration of the sugar molecules is more in concentrated sugar solution.So, as the membrane is a semi permiabe membrane,sugar molecules cannot diffuse across the semi permiable membrane.But the membrane is permiable for water molecules.Therefore the water molecules diffuse through the membrane to the concentrated sugar solution.

Movement of water in and out of a cell through and conc. gradient is called osmosis. Therefore the examples are:-

1) When a potato is put in distilled water the size of the potato become more as there are less water molecules inside and therefore more water molecules go in to get in equilibrium.

2) Vikings tubing is a great example of osmosis.

3) When animal or plant cell is put in pure distilled water they swell up and only the animal cell burst up due to no rigid layer covering it (cell wall made of cellulose) unlike plant cell. When cells kept in conc. water the vice-versa happens thus they shrink.

Osmosis is the process in which water molecules move from higher concentration to lower concentration through a semi-permeable membrane.

Semi Permeable- Allowing only certain things to pass through it.

The membrane allows only a certain amount of certain types of molecules to pass through it.

A good example of Osmosis is:

When you eat something that is really salty, it extracts the water from your body  in order for it to be digested. Then when the part outside has less water from before, your cells use osmosis to transfer the water outside the cell in order to make sure the water level is even on the outside as well as on the inside of the cell membrane.

This is also a reason why salty foods are not good for you. They often take up your water levels in your cells and make you thirstier.

Hope this helps you!

Examples of Osmosis Applied

The following are examples of osmosis for those of you who need to see an example to clearly understand science (like me)…

Example of osmosis 1.

If you put rice into a bowl of water, the water will move into the rice causing them to swell, while causing the water level to drop.

Osmosis example 2.

If a cell is placed in a container which is full of a hypotonic solution (not many solutes) than the fluid in that container will naturally want to be drawn into the cell and this will cause the cell to swell up and rupture (lyse).

Example of osmosis 3.

If a cell is placed in a container which is full of a hypertonic solution, than the cell will lose fluid as it is diffused outof the cell into the area of greater solute concentration. This will cause the cell to shrink (crenate).

Example of osmosis 4.

In medicine, if a patient drawns in salt water, the hypertonic water in the lungs will cause more fluid to be drawn out of the pulmonary arteries into the alvioli and lungs. This will more often result in pulmonary oedema than a patient who has drawned in fresh water.

Example of osmosis 5.

If you admister normal saline to a patient intraveneously (which has the same osmolarity as blood / the same amount of solutes as blood) it will mean that the fluid remains unchanged, because their is no osmotic gradient (basically all the fluid stays the same). Now, if you were to give mannitol (which is a very hypertonic solution) the fluid within the blood will be drawn out of the cells and into the mannitol solution.

Examples of Osmosis in Cells?

This becomes important when looking at the structure of cells in biology.

If a cell has a high concentration of a solute (salt) it will draw fluid into its cell. If allowed to continue to do this, it will eventually swell up and rupture (this is called cell lysis).

If a cell has a low concentration of a solute it will lose fluid as the fluid within its cell is allowed to be drawn out of the cell through osmosis and into the intersitial space. This will cause the cell to shrink (this is called cell crenation).

Practical Examples of Osmosis in Medicine

Basically, this concept becomes important when we start to administer hypertonic or hypotonic solutions. We understand that if we were to admister 100% sterile water intraveneously to patients who are dehydrated, the cells within the vasculature (blood vessels) would draw up all that fluid due to the osmotic gradient shift (this basically means that the fluid will want to shift into the cells) and this will cause the local cells to swell and lyse (rupture). This means that the red blood cells themselves will no longer be capable of carrying oxygen and serving their purpose.

Likewise, if you were to administer 50% glucose intravenously, the hypertonic solution (lots of solutes) will cause a lot of fluid to shift towards it. Now, so long as the canula is in a large vein, it will be able to draw fluid from a large area. However, if the canula is inserted in a small vein or accidentally inserted into the intersitial space and not a vein, it will not be able to draw fluid from all over, and consequently draw all the fluid from the surrounding cells. This will cause the cells to shrink (crenate) and again, become unable to sustain life. In these circumstance, patients may develop cellulitis or damaged veins.

One example would be: When your hands are in dishwater for a long time and your skin bloats with water (not shriveling which is a common misunderstanding) Another is: Putting salt on a slug. Water diffuses out and the slug shrivels up. In both instances the water moves from an area of higher concentration to an area of lower concentration. In other words, the water moves out of your fingers and the slug to try an equalize the salinity outside them both.

Many of these answers are very good in explaining that it is the migration of a solvent from an area of higher concentration to that of a lower concentration.

A simple experiment (if you don't mine killing frog eggs) is to placed a few frog eggs in a solution of distilled water (free from any solutes) and in solutions of varying concentrations of salt (the solute). Notice how the eggs will change in each of the solutions as the water migrates into or out of the eggs.

Osmosis is a phenomenon where water molecules move from a region of higher concentration, through a selectively permeable membrane, to a region of higher concentration.

Moving of water molecules into a cell by osmosis is called endosmosis.

Moving of water molecules outside a cell by osmosis is called exosmosis.

 

A solution in which the solute concentration is less than the solvent concentration is called Hypotonic solution.

A solution in which the solute concentration is equal to the solvent concentration is called Isotonic solution.

A solution in which the solute concentration is more than the solvent concentration is called Hypertonic solution.

EXAMPLE:

  • When you add raisins into a hypotonic salt solution it swells due to endosmosis.
  • When you add raisins into a isotonic salt solution it remains intact.
  • When you add raisins into a hypertonic salt solution it shrinks due to exosmosis.

hey, I am pretty sure that you now know the definition of osmosis but it also helps to know the types of osmosis also. There is Isotonic, Hypertonic, and Hypotonic.  Isotonic is when the cell and the solute are at equilibriam or the concentration gradient is the same.  The water molecules still move but they move equally in and out of the cell.  Hypotonic is when the concentration of solute is greater inside of the cell then outside.  Because of this the cell swells up and will burst. The water diffuses into the cell going from a high concentration to low concentration.  Now, when it is the opposite it is called Hypertonic.  The cell should shrink in size and the cell membrane collapse.  This is what makes plants wilt.

Osmosis is the net diffusion of water from a weak solution to the more concentrated solution when the two are separated by means of a semipermeable membrane. If the solution is separated from its pure solvent the molecules of solvent move from pure solvent to the solution. The movement of water occurs, in osmosis, due to the difference of chemical potential on two sides. The molecules of water move from a solution having more potential to the solution having less potential. Pure water has maximum water potential i.e., it has maximum number of free and active water molecules.

Osmosis is the process of water moving from am area of high concentration to low concentration. Two solutions of different concentration are separated by what is known as a semi-permeable membrane. Osmosis will occur until both solutions have an equal concentration. An easy example would be salt water. Salt will move through the membrane from an area with a lot of salt to an area with a little amount of salt. This will occur until there is an equal amount of salt throughout.

Ah, osmosis.  I love osmosis. Ever since I learned about it in my 10th grade biology class, it's fun to recognize osmosis when I can in my daily life. 

Since you ask for an example of osmosis, it looks like you already know the definition of it. Thus, I will not give you the definition and just a couple examples I know of.

1) When you shower. If you take a look at your fingers after a nice shower, you will notice that they get a little pruny. This is because water from your body exited your skin on your fingers because of all the shampoo and condition on the outside of your skin. The water moved out for better balance in concentration.

2) Another example is when your hands get clammy and sweaty. Some people notice that their fingers and hands feel a little chubbier and/or swollen when their hands get clammy. This is because of the sweat and other more concentrated fluids under your skin. The water from the outside enter into the skin.

Osmosis refers to the movement of one, less concentrated solvent through a semipermeable membrane to another, more concentrated solvent.

The most popular example of osmosis is the animal cells. Our cells have semipermeable membranes that do not allow salt particles to flow in and out. The only way, then, "water down" an over salted cell is to allow water to move back and forth. Therefore when we are dehydrated and drink a lot of water, we are reaching equilibrium in our cells by filling them back up with water.

Osmosis is when you pour colored liquid into another clear liquid and after a while the entire clear liquid becomes colored.
