Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

Connect one end of the white wire to one of the nails and then place the nail into one half of the potato. 3. Connect the other end of the white wire to the battery holder inside the digital clock. 4. Connect one of the pennies to one end of the black wire then put the penny into the same half of the potato as the nail with the connected to it. 5. Connect

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

concentration to an area of low concentration across a semi permeable membrane. An osmotic system is established when a semi-permeable membrane is placed between two solutions. In this biological systems context‚ osmosis is the exchange of water between the potato cell and the surrounding medium of varying sucrose concentrated solutions‚ with the plasma membrane being the semi- permeable membrane. Because water molecules have kinetic energy‚ they are constantly moving around in gaseous or liquid form‚ moving

The grunge look was a popular trend for 90s people‚ whereas the 70s was often known as the “me decade”‚ which is about expressing individuality. 1990s clothing was often baggy‚ and included items such as oversized sweaters‚ flannel shirts‚ denim‚ turtlenecks and solid colors.

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
