    Demonstrating osmosis Introduction The movement of water in and out of a system bounded by a membrane permeable to water‚ but not certain other substances‚ can be inferred by either mass changes or volume changes in that system. It is possible to monitor other changes in physical conditions‚ such as texture. Monitoring mass enables quantification of the changes‚ whereas other changes may only be qualitatively measured.

    Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis‚ I hypothesise that as the solution of the starch in

    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 the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel

    In this experiment‚ we worked with potatoes‚ also known as solanum tuberosum (Watkins‚ n.d). Potatoes are starchy crops that provide a lot of energy. For this experiment‚ our hypothesis was: If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The

    Observations: Three potatoes were placed in three different solutions‚ 40% salt‚ 0.4% salt‚ and tap water. After two days the only significant change was in the potato that was in tap water. It changed from firm to soft‚ 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

    concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain specific requirements for survival. Large amounts of water are absorbed by root hairs and are then distributed across the cells of plants by the process of osmosis; water being essential to

    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

    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
