Explanation:
root pressure
animal cells
water soak. you soak a large number of things in water and you can observe osmosis
Water Soak
You can soak a large number of things in water to literally watch osmosis take place before your eyes. Dehydrated fruits and vegetables are great examples. The water isn’t simply flowing into empty spaces inside the fruit. It is literally passing through the cell walls and re-hydrating the fruit or vegetable. Something such as a raisin will have a very, very high concentration of sugars and water (do not confuse concentration with quantity; the raisin has little water, but it is highly concentrated). Thus, the water flows from a point of low concentration (the cup or bowl of water) to one of high concentration (the raisin). In this way equilibrium is achieved.
Animal Cells
This is by far the most popular example of osmosis, probably appearing in every chemistry textbook in the country. As you will see with many examples of osmosis, this animal cell example involves salt and water. 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.
