    In this lab we will look at how molecules move across the membrane of a cell . Osmosis is the movement of water across a cell membrane.In osmosis the cell membrane is selectively permeable‚which allows for the membrane to control what types of substances that passes through.Transportation can either be passive or active.Passive transport does not require the use of added energy where as active transport requires the cell to use energy. Diffusion is the simplest form of passive transport. Using

    Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion

    The purpose of this lab was to determine the concentration of NaCl or sodium chloride that is isotonic to elodea cells. First off‚ what is osmosis? Osmosis is this huge net of molecules moving through semi-permeable membrane to high concentration to direction where everything becomes balanced. This brings us to what osmolality is. Osmolality is related to osmosis and we know that osmosis has something to do with water so that being said‚ osmolality is number of osmoles of solute per liter in solution

    Investigating the Osmosis Effect in Potato Cores Aim The aim of this experiment is to investigate the osmosis effect in potato cores while they are submerged in different concentrations of sucrose solution. Osmosis will take place while the potatoes are fully submerged in the sucrose solution. Apparatus ľ Scalpel (1) ľ Tile (1) ľ Pr.

    transport in which it does not have need of an active role for the membrane. Osmosis and dialysis are also occasionally called passive transports because they too do not require an active role for the membrane. Osmosis is movement of water across a semipermeable membrane of low concentration to a solution of high concentration. On the other hand diffusion is movement of molecules from a high concentration to a low concentration. Osmosis is a form of diffusion but a distinction would be that it deals essentially

    An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions

    Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

    VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass

    Factors affecting the movement of water through osmosis Introduction In this I will be investigating what effects the movement of water through osmosis. Osmosis is the diffusion of water. It is the process in which fluids pass through a partially-permeable membrane. It is the movement of water from high water concentration to low water concentration. Plant cells react to osmosis by hypertonic‚ isotonic and hypotonic. Keywords Hypertonic – is when the water outside of the cell is lower than
