Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

Compared to the deaths of the holocaust which would stand at 11 million. 94 million is a to high number‚ when dealing with innocent lives. The Potato Eaters‚ a painting by Vincent Van Gogh‚ a novel by George Orwell published in 1954‚ and “Dog‚” a 1977 song performed by Pink Floyd and written by David Gilmour explore the idea that communists countries have harsh conditions that will be apart of

Effect of Osmosis on Potato Aim: To investigate the effect osmosis has on potato pieces that are placed in different concentrations of sugar solutions in water. Hypothesis: I believe that the more saturated the solution is the lighter the potato will be‚ and the potato in the clear water will weigh more after being left in the solution over a 24 hour period. This is because the cell membranes in the potato act as semi permeable membranes (meaning that they only allow certain molecules through)

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)

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product
