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

Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at other times the molecular movement from one direction exceeds the movement from other direction and creates a net movement. This net movement is called osmosis. Osmosis is due to differences

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids. Materials and methods: * 20 mwco dialysis membrane * 50 mwco dialysis membrane * 100 mwco dialysis membrane * 200 mwco

The changes in the diffusion of Buddhism and Hinduism through 600 CE greatly impacted these religions such as the popularity of the religions in India and where the religions was being diffused; however‚ a few continuities existed such as they both originated in India. Since Hinduism reinforces the caste system and Buddhism believe in equal treatment of all people which opposes the caste system‚ Buddhism started to spread into other areas other than India to offer an alternative to Hinduism for

Since 1980s‚ the coagulase-negative staphylococci (CoNS) ) is a primary consideration in the rise of surgical site infections. The Staphylococcus epidermidis is the predominant CoNS on human skin and methicillin-resistant are the isolates of CoNS that showed an increasing amount where perioperative prophylaxis are not effective‚ methicillin-resistant Staphylococcus epidermidis (MRSE) is then used in the study. The aim of the present investigation was to evaluate staff of the operating department

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

The purpose of this experiment was to determine the effects of temperature on the elasticity of rubber bands. There were three hypotheses: If the 0.157 cm rubber bands are heated to about 100˚C in water for one minute‚ then the rubber bands will stretch to approximately 60 cm; If the 0.157 cm rubber bands are cooled to 0˚C in water for one minute‚ then the rubber bands will stretch to approximately 40 cm; If the 0.157 cm rubber bands are left in room temperature water for one minute
