Fill both of the dishes with water and add about two tablespoons of salt to one of the dishes. Using the knife have a parent cut the potato in half lengthwise. Then Place each piece flat side down in to one of the plates of water.

Now simply let the two potato pieces soak in the water for a few hours. After this time has passed flip each potato over and look for differences.

When looking at the potato pieces you can clearly see a difference between the two.

Osmosis - Wikipedia

Lets take a closer look at each of the potato pieces! This potato slice is the one that has been soaking in freshwater. Not much of a difference here, only that the potato is a little more rigid then before. This is because there is the more salt and other dissolved chemicals within the potato then the surrounding water.

This means that the water will move into the potato. This potato slice is the one that has been soaking in saltwater. This potato pieces looks substantially different from the original and the other slice.

It seems to have wilted, gotten very soft and flexible.

Why did that happen? It has to do with a process called osmosis. The potato is made up of tiny, living units called cells. Each cell is surrounded by a cell membrane which acts much as your skin does.

It keeps the cells parts inside and keeps other things outside, protecting the cell. While this membrane stops most things, water can pass through it. The water tends to move towards higher concentrations of dissolved chemicals.

That means that if the water outside the cell is saltier than the water inside, water will move from the inside of the cell to the outside.

As the water left the cell it was much like letting the air out of a balloon. As more and more of the cells lost water, the slice of potato became soft and flexible.Moreover sole finding out, there are a couple additional methods to analyze that will not only reward you, but osmosis coursework other pupils in your course.

You can shell out the rate online, but specified providers will demand a large volume which can’t be paid on time. The Osmosis Flashcards are not only extremely relevant, but they also feature cross-references to additional resources.

These flashcards, in conjunction with the Osmosis spaced repetition method, have helped me to remember details that I studied from past semesters.
