To Investigate the Effect of different Concentrations of Sucrose Solution on Potato Sticks Plan Osmosis is the movement of water though a differentially permeable membrane from a weak concentration to a higher one. Water solutes move freely through the cellulose wall of plant cells. However the plasma membrane binding the cytoplasm in plants and animals is selective like a sieve, only letting water or other small molecules in. Osmosis is a type of diffusion; it is a passive process in which water molecules are moving down a diffusion gradient. Plants take in water via osmosis to be used in photosynthesis, however it is also important for keeping the plant rigid. When water is diffused through the cell membrane from a high concentration to a lower one, the cytoplasm in the cell presses against the cell wall making it turgid, thus keeping the plant upright and rigid. But when the concentration of water is...
