Mikhael 2nd GCSE Boukraa Biology COURSEWORK The effects of osmosis in plant tissues PLANNING: This experiment will entail the observation of osmosis. The effects osmosis has on a cell are either that it becomes turgid and hard as water enters the cell or it becomes dehydrated (this is called plasmolysing in plant.

When the potato chips were removed from the test tubes and dried some groups may well have dried some potatoes more thoroughly than others and so some would have more excess water, which would add to the mass. Register Log in Sign up with one click: Back to It's a green world index. The potato tubes will all be cut out of the potato using a cork borer and will all be cut to the length of 25mm. The term osmotic pressure refers to the amount of pressure necessary to stop the flow of water across the membrane. Plant cells have a strong rigid cell wall on the outside of the cell membrane. If the water concentration inside the cell is the same as that in the surrounding medium i. For example, freshwater and saltwater aquarium fish placed in water of a different salinity than that to which they are adapted to will die quickly, and in the case of saltwater fish, dramatically. Osmosis explains how water moves in and out of animal cells through the cell membrane. My experiment involves soaking potato chips in different strengths of glucose solution to see if the mass of the potato chip changes. The mechanism responsible for driving osmosis has commonly been represented in biology and chemistry texts as either the dilution of water by solute resulting in lower concentration of water on the higher solute concentration side of the membrane and therefore a diffusion of water along a concentration gradient or by a solute's attraction to water resulting in less free water on the higher solute concentration side of the membrane and therefore net movement of water toward the solute. George Routledge and Sons, , p. Its History, Construction, and Application Water so purified can be used in hemodialysis. The process is reversed as soon as the cells are transferred into a hypotonic solution deplasmolysis. A gradual, often unconscious process of assimilation or absorption: Please consider upgrading your browser software or enabling style sheets CSS if you are able to do so. Activity Revision Map Give your revision some visual style with a Bitesize revision map! Central vacuole collapses and plasmolysis occurs. When a red blood cell draws in water and bursts in this way, the cell is said to undergo hemolysis. Prediction I predict that the higher the water potential of the water outside the plant, the quicker osmosis will take place.
