Web30 jul. 2024 · Dialysis tubing is used to simulate a cell membrane; it is permeable to small molecules and water, but not to larger molecules. Given the generally larger size of polysaccharides, it is hypothesized that starch will not pass through the dialysis tubing, and that iodine will pass through the membrane due to the small size of its molecules. WebThe cell membrane is very elastic (like a balloon). Special adaptations allow some animal cells to live in hyper and hypotonic solutions. Plants generally depend on a hypotonic environment for water uptake. When placed in water, the water will move into the plant cell, but the cell wall surrounding the cell membrane is not very expandable.
