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:

Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

Osmosis and Scientific Method Lab Report Abstract The purpose of the lab is to see how different size potatoes have faster water movement depending on the concentration of sucrose it was placed in. We had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the

Reverse Logistics in Indian Automobile Industry Reverse Logistics is a process in which a product moves in reverse through the supply chain network. It may be used for the purpose of recapturing value of a final product or for even proper disposal. It may also be termed service that the process of planning‚ implementing and controlling the efficient and cost effective flow of raw materials‚ in-process inventory‚ finished goods and related information‚ from the point of consumption to the point of

The book A Raisin in the Sun had many themes‚ motifs‚ and symbols. Value/Purpose of dreams (theme)‚ Home (Motif)‚ and Mama’s Plant (symbol) had many similarities and differences. Value/Purpose of dreams are each of the Younger’s dreams throughout the play. Beneatha wanted to be a doctor‚ Walter wanted to buy a liquor store to start a business‚ Mama wanted to own a garden‚ Travis wanted to be a bus driver‚ and Ruth wanted to get out of the “rat trap.” When the Youngers fail to make their dreams reality

Managing product returns for reverse logistics This paper provides a framework to manage product returns for reverse logistics. It takes a specific product catalog in India as an example. It utilizes an integrated framework to estimate returns of products. Next step‚ it makes decisions on operations‚ such as disposition‚ location and capacity of facilities. After that‚ take strategic‚ operational and customer service-related constraints into to consideration to give a time horizon for returned

Title: Egg Osmosis Purpose: The purpose for doing this lab is to show how Osmosis takes place. It is supposed to show how the eggs would react to a change in their environment. The way to show how it would change would be putting eggs in different controlled environments. Each of the eggs will be put in three different environments. Vinegar‚ Karo Syrup‚ and water. Each egg will have to have a documented reaction that each will have. Introduction: The lab will allow us to see and explain each

Brianna Nichols Per.1 11-10-12 A Raisin in the Sun A Raisin in the Sun by Lorraine Hansberry is a truly exquisite piece of literature that has influenced readers‚ young and old‚ for generations. It gives us a very realistic view of racial tension‚ as well as the socioeconomic struggles‚ African Americans faced during the late 1940s-50s. In this play we meet the Youngers‚ a lower-class‚ diverse-minded‚ African American family simply trying to survive in 1950s South Chicago. Together they
