Water Relations In Cells

Name

Water Relations in Cells

Sketch each cell and determine whether cell is hypertonic, isotonic, or hypotonic compared to its environment and label appropriately. Use arrows to indicate the flow of water in/out of the cell and make a prediction, using correct terms, about what will happen to the cell. plant cell in distilled water

protozoan in creek water (usual habitat)

egg without shell in hypertonic solution





plant cell in salt water

protozoan in salt water (not usual habitat)

egg without shell in solution that causes no gain or loss of mass

dialysis (membrane permeable to both sugar and water) Sketch your prediction: initial final

animal cell in tissue fluid

cheek or blood cell in hypotonic solution



thistle tube of sugar water in distilled water (membrane impermeable to sugar)

When are two solutions at equilibrium but not isotonic?
