akshay: Osmosis in our Daily Life
Learn about and revise diffusion, osmosis and active transport with BBC Bitesize for The slideshow shows an example of osmosis showing the direction of. Absorption of water by roots of the plants is an example of osmosis. Roots of the plants Osmosis plays a very important role in our daily life. Posted 1st Insulin is an important hormone that controls many processes in our body. . In a beautiful relationship, not all the days are passionate and romantic. Osmosis has a number of life-preserving functions: it assists plants in receiving water, it helps in the preservation of fruit and meat, and is even used in kidney.

This probably seems like a fatal flaw, but surely no slug expects to have pure salt dropped on it. But when such a thing does happen, the high concentration of the salt on the outside of the slug causes the cells to start trying to balance concentrations.
Examples of Osmosis for a Better Understanding of the Concept
The slug will dry up and die if enough salt is applied. Root Pressure I mentioned animal cells above, but plant cells work in the same fashion and are just as popular for osmosis examples. You can learn everything a non-professional would want to know about biology in just a few short weeks with this awesome intro to biology course.
Cholera Osmosis allows for terrible things to happen, as well. Cholera would not be possible without osmosis. In other words, it changes the way ions and, subsequently, water are transported in our intestines. So what does this mean, exactly? It means that the cholera perform a perfect coup. Just the opposite, in fact. Now osmosis happens in the other direction and water moves from our intestinal cells into our intestines.
Second, this compounds the rate at which you get dehydrated. Not only can you not absorb water, you are literally being drained dry. Dialysis is the process by which an artificial kidney machine removes waste products from a patients' blood—performing the role of a healthy, normally functioning kidney.
The openings in the dialyzing membrane are such that not only water, but salts and other waste dissolved in the blood, pass through to a surrounding tank of distilled water. The red blood cells, on the other hand, are too large to enter the dialyzing membrane, so they return to the patient's body.
Preserving Fruits and Meats Osmosis is also used for preserving fruits and meats, though the process is quite different for the two.
In the case of fruit, osmosis is used to dehydrate it, whereas in the preservation of meat, osmosis draws salt into it, thus preventing the intrusion of bacteria. To preserve fruit, it must be dehydrated, which—as in the case of the salt in the meat—presents bacteria with a less-than-hospitable environment. Over the years, people have tried a variety of methods for drying fruit, but most of these have a tendency to shrink and harden the fruit.
The reason for this is that most drying methods, such as heat from the Sun, are relatively quick and drastic; osmosis, on the other hand, is slower, more moderate—and closer to the behavior of nature.
Osmotic dehydration techniques, in fact, result in fruit that can be stored longer than fruit dehydrated by other methods. This in turn makes it possible to provide consumers with a wider variety of fruit throughout the year. Also, the fruit itself tends to maintain more of its flavor and nutritional qualities while keeping out microorganisms. First the fruit is blanched, or placed briefly in scalding water to stop enzymatic action.
7 Examples Of Osmosis In Everyday Life
Next it is subjected to osmotic dehydration by dipping it in, or spreading it with, a specially made variety of syrup whose sugar draws out the water in the fruit. After this, air drying or vacuum drying completes the process. The resulting product is ready to eat; can be preserved on a shelf under most climatic conditions; and may even be powdered for making confectionery items.
Whereas osmotic dehydration of fruit is currently used in many parts of the world, the salt-curing of meat in brine is largely a thing of the past, due to the introduction of refrigeration.
Many poorer families, even in the industrialized world, however, remained without electricity long after it spread throughout most of Europe and North America. John Steinbeck's Grapes of Wrath offers a memorable scene in which a contemporary family, the Joads, kill and cure a pig before leaving Oklahoma for California.
And a Web site for Walton Feed, an Idaho company specializing in dehydrated foods, offers reminiscences by Canadians whose families were still salt-curing meats in the middle of the twentieth century. Verla Cress of southern Alberta, for instance, offered a recipe from which the following details are drawn.
First a barrel is filled with a solution containing 2 gal 7. The pig or cow, which would have just been slaughtered, should then be cut up into what Cress called "ham-sized pieces about lb [ kg] each. Then hang it up in a cool dry place to dry. It will keep like this for perhaps six weeks if stored in a cool place during the Summer.
Of course, it will keep much longer in the Winter.
If it goes bad, you'll know it! Instead of salt, sugar is used in a mixture of 32 oz. After being removed, the meat is smoked—that is, exposed to smoke from a typically aromatic wood such as hickory, in an enclosed barn—for three days.

Smoking the meat tends to make it last much longer: Also included were reminiscences by Glenn Adamson born We cut up the pig into maybe eight pieces and put it in the brine barrel. The pork soaked in the barrel for several days, then the meat was taken out, and the water was thrown away….
In the hot summer days after they [the pieces of meat] had dried, they were put in the root cellar to keep them cool. The meat was good for eating two or three months this way. Meat was not the only type of food preserved through the use of salt or brine, which is hypertonic—and thus lethal—to bacteria cells. Among other items packed in brine were fish, olives, and vegetables. Osmosis in the Body Salts and minerals from water are transferred through osmosis.
Water flows through the plasma membrane of cells and due to osmosis, concentration of water, glucose and salt is maintained inside the body.
It is important in preventing cell damage. Osmosis and Saltwater Fish Saltwater fish are adapted to high saline water bodies.
Since, salt concentration of the water is higher than the fish, the excess salt in the surrounding water draws water from the body of the fish. This is how osmosis is regulated.
Osmosis and Freshwater Fish Freshwater fish maintain fluid balance in their body through osmosis. Since the salt concentration in their body is higher than the surrounding water, they do not need to drink water.
Supplying the cell
This is because water is spontaneously absorbed by the salt present in their body. Osmosis plays a very important role in human life as it helps in the proper functioning of the kidneys. It occurs in the kidneys to recover water from the waste materials of the body. Dialysis as an Example of Osmosis Kidney dialysis is an example of osmosis. It is for patients suffering from kidney diseases.
In this process, the dialyzer removes waste products from a patient's blood through a dialyzing membrane, and passes them into the dialysis solution tank.
