Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

GCSE - Human Physiology and Health An experiment to investigate what affect sucrose solution has on potato tissue. Background Osmosis is the movement of water molecules‚ across a partially permeable membrane from a region of high concentration of water to a low concentration of water molecules. A partially permeable membrane is a membrane with holes in it small enough for only water to go through it. Big molecules like glucose cannot fit through it. Osmosis allows plants to take in water

Controlled Assessment: Osmosis of a Potato [pic] Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides. Biological membranes do allow water to pass through‚ but water will have no net movement unless osmosis takes place. Preliminary Method I have chosen to investigate the factor of the weight of potato strips after set amounts of time.

are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house

Results The relative osmotic concentration was determined by measuring the percent change in mass of the potato tissues. Change in mass was measured of six solutions‚ each containing different levels of concentration (0‚ 0.1‚ 0.2‚ 0.3‚ 0.4‚ and 0.5). The percent change in mass decreased as sucrose concentration increased‚ therefore‚ relative osmotic concentration also decreased as sucrose concentration increased. However‚ the osmotic concentration of 0.2 M sucrose solution was relatively greater

Effect of Osmosis on Potato Aim: To investigate the effect osmosis has on potato pieces that are placed in different concentrations of sugar solutions in water. Hypothesis: I believe that the more saturated the solution is the lighter the potato will be‚ and the potato in the clear water will weigh more after being left in the solution over a 24 hour period. This is because the cell membranes in the potato act as semi permeable membranes (meaning that they only allow certain molecules through)

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen

Null hypothesis The concentration of sucrose in the soil will not affect the growth of the common wheat seeds. Alternative hypothesis The concentration of sucrose in the soil will affect by slowing down the growth of the common wheat (Triticum aestivum) seeds. The sucrose solution (sucrose mixed with water) added to the soil makes high concentration outside the common wheat cells and the common wheat cells become an area of low concentration. Because the osmosis is reversed‚ the
