So, you are to write an osmosis coursework. Let us see what we can do for you. Thus, for instance, let us first define the essence of osmosis. Osmosis is defined as a process of diffusion of water in a cell or a membrane; this can be described as a physical process, in which a resolvent moves without any source of energy.
 
In order to succeed in writing your osmosis courseworks, you are to investigate this problem in details, thus, for instance:

• In your osmosis coursework you may research the degree of osmosis importance in the biological system and biological membranes;
• In your osmosis coursework you may investigate the process of osmotic pressure as the main reason for receiving support in plants;
• In your osmosis coursework you are also welcome to study the osmotic gradient, which lies in the differentiation of one solution from another in accordance with the degree of concentration;
• You can also research the process of the reverse osmosis in your osmosis coursework, which is the process of separation of one solvent from another.

Do not forget that your osmosis coursework presupposes some experiment, where you can show the essence of this process. Some scientists take the interaction of potato with salt solution to carry out their experiment. You can also resort to it when conducting the experiment for your osmosis coursework.
 
Still, to impress the committee you are to bring some fresh air into this problem. So, when presenting your osmosis coursework, you can show the experiment itself, this will not spoil your defense, but only add some scores to it. Besides, you can use some pictures describing this process. It will be even twice better if you design them by yourself with the help of the computer.
 
Good luck!
