______ 1. Background: Potato is a starchy‚ tuberous crop from the perennial “Solanum tuberosum” of the Solanaceae family (also known as the nightshades). It originated from the area of present-day southern Peru and it’s now grown worldwide. Potatoes were first introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world ’s cuisine. It is the world ’s fourth-largest food crop‚ following rice‚ wheat‚ and maize. Wild potato species occur throughout

length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement

of a Potato Mishal Hasan Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation‚ several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it was isotonic. Anything above caused the potato to gain weight showing that it was a hypotonic solution and anything below caused the potato to lose

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

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
