Iv analysis table i was an example of diffusion the amber color in the beaker over a 30 minute time period slowly leaked into the dialysis tubing causing it to become a blue-black color osmosis also occurred in this experiment because while glucose passed through the tubing other molecules did not as shown with the blue black color instead of amber after 30 minutes. Potato and osmosis investigation planning: (p) some background information: water potential and living plant cells plant cells in pure water: if plant cells are placed in pure water (a hypotonic solution) water will initially move into the cells. Through osmosis, water molecules move in order to make the water potential and concentration of the surrounding solution and the vegetable equal the reverse occurs when the concentration of the surrounding solution is very low (lower than the vegetable.

Osmosis in potatoes coursework, osmosis is a type of diffusion involving water molecules and a semi-permeable membrane they move from areas of high water concentration, such as dilute solutions of say, sugar, to areas of low water concentration, such as con. In conducting an incident investigation, the team must look beyond the immediate causes of an incident it is far too easy, and often misleading, to conclude that carelessness or failure to follow a procedure alone was the cause of an incident. In this coursework experiment i plan to find the rate of osmosis in different vegetables (carrot, potato, swede, parsnip and sweet potato) i will measure the mass before and after the experiment to use the results to calculate the rate of osmosis, and to find trends in the vegetables. Introduction: diffusion and osmosis lend themselves to visual demonstration and are pretty simple, so why should we have all the fun (and do all the work) as the 'membranes' topic falls early in the course, this is an ideal opportunity for students to develop independent research and practical investigation skills - they will be required to find out about their own demonstration, order their.
