the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

Osmosis in potato cells Aim: To view and examine the effect different concentrations of sucrose solution has on the movement of water across the cell membrane. Hypothesis: That the potatoes will either increase or decrease in mass‚ due to the effect of the different concentrations. Osmosis will occur. Apparatus: * Fresh potatoes * Apple corer * Scalpel * Petri dishes X 10 * 50ml measuring cylinder * Distilled water * Paper towelling * Sucrose solutions:

The Potato Epidemic One fine morning in the Kingdom of Sandwiches‚ SandwichKing and Sandwich‚ his pet‚ were going for a walk. Suddenly‚ green potatoes‚ “The SWAT‚” came out of nowhere and asked a million questions about mashed potatoes? Then suddenly‚ as fast as they had appeared‚ they disappeared. “Who was that?” asked SandwichKing‚ “And what do they want with mashed potatoes? Whatever.” Then SandwichKing and Sandwich continued on their walk. The next day‚ when SandwichKing looked out his window

I. Research Question What are the effects of different sucrose concentrations on potato stripes which have been submerged in a range of solute sucrose concentrations. II. Background Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the

I A. The autumn of 1856 was a time of great starvation for Ireland. B. Many people were affected by the Potato Famine because the potato was their staple crop. C. The population during the famine dropped from 8.1 million to 6.8 million. D. Why was the famine so severe even though it was during the modern age? Thesis: The impact of the Irish Potato Famine would not have been as devastating if England hadn’t controlled Ireland by foreclosing thriving industries‚ passing

Objective: To observe the effects of osmosis on eggs placed in vinegar (5% acetic acid)‚ syrup (60% sugar solution)‚ and water (100% distilled). Hypothesis: Hypothesis #1: It was hypothesised that the egg would gain 59 grams of mass after soaking in vinegar for 24 hours. Hypothesis #2: It was hypothesised that the egg would become larger when soaked in syrup than it once was due to the hypotonic environment. Hypothesis #3: It was hypothesised that the egg would soak in water for 72 hours‚ losing

The Growth in Potato Production and Inception of Secondary Potato Markets in India Case Study: McCain India Limited Potatoes are a staple food crop in most developed and developing nations. The original habitat of South America was discovered by Europeans when Columbus landed on Latin American soil. However‚ the potato was adapted as a field crop only during the late 16th and early 17th century1. Global

MOTOR TEMPERATURE RATINGS A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe‚ in basic terms‚ the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms. MOTOR SURFACE TEMPERATURES
