I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment‚ its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)

How do our Reactions to Obstacles and Hardships Help to define us as Individuals? As our fragile minds go through adolescence and on to adulthood‚ we face obstacles that are put in our way that shape and define us as human beings. Some people tend to crack under the pressure others trudge through it challenging and pushing themselves to their limits. We aren’t always alone we have people that are there to help us along the way and sometimes they leave their mark on you like on the last shot in

Chlamydia is the most common bacterial sexually transmitted infection (STI) in Canada. When left untreated‚ it can lead to painful physiological problems and sterility defects. Despite being in decline for many years‚ rates of chlamydia infection have risen steadily since 1997. These rising rates show that people are not using safer sex methods on a consistent basis. This STI is transmitted through vaginal‚ anal‚ or oral sex‚ and can also be transmitted from mother to child during childbirth. Chlamydia

Osmosis is the net movement of water from a high concentration of water to a low concentration of water down a concentration gradient. This is done to equalise the solute concentrations on the two sides. Therefore‚ in other words‚ the movement of water is depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced
