Biology Osmosis
Essay title: Biology Osmosis
Investigation into finding out the
Effect of the effect of osmosis
In potato cells
Introduction
I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution.
Osmosis is a process which water moves from an area of low concentration to an area of high concentration.
I am going to record my results to see if osmosis occurs in water solution of sugar solution.
Apparatus
In this experiment I would need; –
1) 3 test tube
2) A beaker
3) A cork borer
4) A Knife
Safety
In this experiment safety will not be a major hazard as itâs not a very dangerous experiment apart from the knife which Iâm using to cut the potato pieces which I need to be careful with and make sure my fellow students donât get harmed by my miss use.
Hypothesis
I predict that water will occur in the water solution as I stated earlier âwater moves from an area of high concentration to a area of low concentrationâ which in this case the water will move into the potato making it turgid where as the potato piece in the sugar solution will become flaccid due to the potato containing a high concentration of water.
Fair testing
I must ensure that my test is going to be fair because if itâs not fair the test will be biased and my result would be incorrect.
I will try to keep it fair however there are variables I can ânot control like what happens when I leave the potato pieces alone over night for 96 hours.
