Factors that cause the rate of osmosis to increase Other than temperature and concentration, are there any other factors that would cause the rate of osmosis to increase? light intensity and temp are linked - they increase the energy of the particles and also cause evapouration which means the ... of osmosis from solution to potato and maybe increasing the osmosis from potato to solution. the shape effects the surface area - the greater the surface area the greater the chance of osmosis occuring increasing the rate. Time - the greater time the potato left for the more likely osmosis is to ...
GCSE osmosis in potatoe chips I have to do coursework on osmosis using potatoe chips, but i do not understand the concept of osmosis and what to put in my introduction ect, can someone please help me, thank you. Explaining osmosis would take quite a long time, so it is better to direct you to useful ... sites: http://www.purchon.com/biology/osmosis.htm http://www.tvdsb.on.ca/westmin/science/sbi3a1/Cells/Osmosis.htm The first site contains more detail, the second is a bit brief but includes animated diagrams which are quite useful. Yoy could also check out bitesize revision on the BBC site ...
Osmosis coursework i have just received my c/w for OSMOSIS with potatoes. i haven't got a clue of what to do, since i have started new to Double Science therefore i need help on this topic. How can i find information on the net? what websites? have you got any information that you can provide me ... osmosis on the BBC bitesize site, http://www.bbc.co.uk/schools/gcsebitesize/. Examples of coursework on osmosis in potatoes can be found at http://www.studentcentral.co.uk/coursework/GCSE_Coursework/Biology/Osmosis ...

osmosis in potatoes can you give me a brief introduction to osmosis in potatoes for a piece of coursework. is it any different to other osmosis? Osmosis is a biological process - it does not vary according to the type of plant. A good account of osmosis can be found at http://www.psionica.co.uk ... biology/KS4Biology/osmosis.htm
Work: osmosis
osmosis Your osmosis theory is not quite right. You say "When the fluid is equal on both sides osmosis will stop" When the CONCENTRATION of both sides is equal, osmosis won't STOP, but an equal amount of water will be travelling in both directions. Osmosis is a two way process. When you say "water ... i.e. 4-5 solutions). Also, you don't have the actual concentrations of the sugar - this is poor science (though it may not be your fault if that was what you were provided with). Given these limitations, a C grade is the highest you are likely to get for this piece of work. osmosis- madiha.doc
Exchange Question: Osmosis
Osmosis what is the role of osmosis in plants ? osmosis works throughout plants to help them grow. during the transpiration cycle (a process that plants give off water vapors), plants move water from the soil through roots and stems to leaves and into the outside air. water enters the roots in a ... process called osmosis. osmosis is the push that water gives as it tries to make plant roots as full of water as the damp soil around them. when the root is full of water, osmosis works to carry water through cell membranes into the xylem (think of xylem as pipes) that carry the water from roots to ...
Work: Osmosis
Osmosis This is a sound piece of work, with only a couple of alterations necessary. In your first section, you say "At this point there will be no change in the length, volume and mass of the potato, as the net movement of water will be zero, no osmosis has occurred." Actually, osmosis HAS occurred ... it is just that the osmosis in both directions balance. If you finish the senetnce at 'zero', you'll be OK. In evaluation, you say "Further work could be carried out to include concentrations that increased in 0.1 M rather than 0.2M. This would increase the accuracy and improve the graph. " HOW ...
Exchange Question: osmosis in Potato Chips
osmosis in Potato Chips I am doing a courework on osmosis in potato chips and i ahve done every but i need help with writing my analysis and evaluation. i need help really bad. Evaluation/Analysis Overall I think this experiment was successful.The accuracy of the investigation was adequate. I ... of the experiment as although I was recording my results by mass, it could have well affected the surface area and so the overall rate of osmosis. Osmosis is the passage of water molecules from where there is a high concentration to where there is a low concentration through a partially permeable ...
Osmosis in a potato Cell "Osmosis is the movement of particles from a higher concentration to a lower concentration" WATER MOLECULES, not particles - osmosis ONLY refers to water.You also need to make it clear that you are talking about lower and higher concentrations of WATER. ("Low concentration ... of results that I could use to produce graphs. " Being able to plot a graph does not mean the results are OK! I'm afraid there is quite a lot of evidence here of misunderstanding of both osmosis and of experimental technique. I really think you ought to discuss this with your teacher. Osmosis CW.doc
