membrane will push against cell wall‚ causing the cell to become turgid. However‚ animal cells do not have cell wall and huge gain of water molecules will cause the burst of the cell. The main purpose of this practical work is to observe the osmosis in potato cubes‚ onion epidermis cells and visking tubes. To examine the effect of different concentrations of sucrose solutions on the plant cells and dialysis tubings. Hazards Precautions Sharp knife‚ scalpel‚ broken glass may cause injuries.

cubes of potato would gain or lose weight depending on the amount of molar concentration of sucrose they soaked in. Solutions made of different molar concentrations of the solute sucrose were prepared before this lab. Potato cubes were weighed and recorded as the initial mass in the data. Four cubes of potato were placed into 100 mL of each solution and let stand overnight. The cubes were then taken out for the final total mass to be measured and recorded. In this experiment‚ the potato cubes were

effect of different concentrations of sucrose on the mass of a potato cell. Results for Part One suggested that the molecular weight of albumin and starch was too large to pass through the dialysis tube‚ but glucose and sodium sulfate molecules were small enough to pass through the dialysis tube. Also‚ a decrease in water weight occurred due the dialysis tube being placed in a hypertonic solution. Results for Par Two showed the potato cell having a molar concentration of 0.2734‚ which caused sucrose

Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled variable: - Equal size of potatoes used - Using measuring cylinder Equipment used: - Gas collecting kit - Potato - Stop watch - Test tube - Distilled water - Hydrogen

This report was written to explain and present the results gathered in a precise and organized manner. This experiment was divided into two parts. The first part concentrated on the placing potato cylinders in different sucrose concentrations for a period of time. This part was conducted to see if the potato cylinders would gain weight or lose weight because of osmosis. The second part was conducted to see if a dialysis bag‚ filled with sodium sulfate and starch solution and placed in an albumin/glucose

This gene helped to kill the Colorado potato beetle without the use of pesticide sprays. Public concern for the New Leaf potato began to grow. Fast food chains such as McDonald’s and Burger King‚ quietly urged their French-fry suppliers to stop using the genetically modified potato. People didn’t like the idea of eating something that

Abstract This investigation was undertaken in order to observe the effects of changing the temperature of the solution that a potato cube is placed in. The temperatures that were tested in this investigation were 0°C‚ 20°C (room temperature)‚ and 70°C. This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again weighed
