    small molecules to pass through - the larger the organism‚ the smaller the surface area ratio.Therefore if ratio is too small it take molecules much more longer to enter cell. Prediction For the experiment‚ I expect to see different effects on potato samples depending on different water concentration: · After putting in dilute solution I expect their mass to increase‚ as effect of taking up water by osmosis - cell should become ‘turgid’. · Concentrated glucose solution - mass of potatoes samples

    HouseholdHacker.com.­ First‚ let’s examine the idea of powering any electronic device with a fruit or vegetable. The concept is believable because you can create a battery with a few potatoes. This experiment is a science class favorite because it helps demonstrate how the galvanic cells that make up a car battery work. Some batteries use galvanic cells to transfer chemical energy into electric energy. They depend on two metals‚ a cathode or positive terminal (such as copper) and an anode or negative

    Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially
