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

within a cell are called Diffusion. When molecules move across a cell membrane it is known as Osmosis. Diffusion is the process by which molecules of a substance move from areas of higher concentration of that substance to areas of lower concentration. Diffusion can be the transfer of anything anywhere. However‚ that is not true for osmosis. Osmosis is diffusion‚ but a specific type of diffusion. Osmosis is only the diffusion of water molecules through a selectively permeable membrane and a concentration

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

Question 1: How does Osmosis works It refers to the movement of water molecules from an area of high-level water concentration‚ that is‚ a dilute solution‚ to an area of low-level water concentration‚ that is‚ a strong solution through a semi-permeable membrane. (Passmyexams.co.uk‚ 2015) Actually‚ water moves in a bi-directional manner with the aim of leveling up the concentration. However‚ a high number of water molecules move from the fresh water towards the salty water. The outcome

The Reverse of Disorder in Cruel Intentions Sex‚ revenge‚ manipulation‚ seduction‚ and love are the table turners in the teenage drama “Cruel Intentions”. The movie is a present day version of the classic ``Dangerous Liaisons’’ in which Kathryn and Sebastian‚ two wealthy‚ manipulative teenage step-siblings from Manhattan’s upper-side‚ conspire to ruin the lives of the individuals around them. The elements of danger are high when the twosome agrees to take part in a gamble of sexual corruptions.

while the other two potatoes remained firm. There was also an awful odor that only came from the potato in the tap water. Conclusion: The hypothesis was correct. The 40% salt solution killed the sailor. This solution was hypertonic which causes osmosis to move the water out of the cell. The sailor then became too dehydrated and died. Salt absorbs water‚ which is why drinking salt water is not good for
