OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

Diffusion through a Membrane Introduction Molecules are constantly moving. They move in straight lines unless they are deflected by other molecules or obstacles in their environment. Diffusion is the process by which the collisions between molecules cause them to continually spread apart from each other. Their movement can be described as movement from an area of greater concentration to an area of lower concentration. Diffusion continues until the molecules are equally distributed

AHP216 04/16/13 I. Introduction: The purpose of this experiment is to observe the osmosis reaction in a potato with salt and water. In cooking cooks will soak their cut potato’s in water if they will not use them immediately. This allows the potato’s to be used later without turning color. The experiment shows the flow of water through the membranes of the potato with salt over a period of four hours. II. Objective: The reaction of the potato to the side submerged in water and the half excavated

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions

OSMOSIS LAB BACKGROUND INFORMATION. Dialysis tubing is being used to model a plasma membrane. Isotonic solutions are solutions that have the same concentration of solutes on both sides of the membrane. Hypertonic solutions are solutions that have more solute to the one with less solute. Hypotonic solution are solutions that have less solute to the one with more solute. RESEARCH QUESTION:which dialysis tubing will gain the distilled water and which one will loss its content

Dryland Agriculture Bayero Unoversity Kano. Abstract Serum haematology and biochemical profile of weaner rabbits fed graded levels of yam peels replacing maize were evaluated. The experiment which lasted fifty-six days using 15 weaner rabbits was laid in a randomized complete block design using five dietary treatments with three replications each. The dietary treatments evaluated were 5%‚ 10%‚ 15%‚ 20% and 0% inclusion level of yam peels replacing maize. Results revealed significant (p<0.05) differences

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
