Osmosis In A Potato
My biology coursework is based round the osmosis process that takes place in potatoes. Osmosis is the intake of a salt solution through a selectively permeable membrane. The strength of a salt solution can have a dramatic difference on the amount the potato can take in, and how it reacts.
Here is an example of a selectively permeable membrane...
An fundamental necessity in my biology experiment is to decide which variable I am going to use and modify. A variable is an aspect of the experiment which can be modified in order to change the outcome of the entire osmosis experiment. Below are the variables I have available
* Solution Strength
* Size Of Potato
* Weight Of Potato
After a lot of careful deliberation I have decided to use the solution strength as my variable. I chose this because it enables me to witness the effect different strengths of solution have on osmosis.
To carry out my experiment successfully I will need to stick to the diagram below....
Firstly, I will take 6 test tubes
