Elodea Cell – Hypotonic Solution Elodea Cell ... When animal cells are in a hypotonic solution, they can undergo lysis. However, plant cells do not, they only become turgid. a. Define lysis based on the diagram in the diagram below. b. What structure on the plant cell prevents lysis from occurring in a hypotonic solution?

water will rush into the cell in attempt to reach a state of equilibrium. An ideal hypotonic solution is distilled water, because it is devoid of solutes. As the cell begins to fill with solvent, the cell will swell, and perhaps burst. The bursting of cells in a hypotonic solution is called cytolysis. 2.

presence of a hypotonic solution, instead the turgor pressure increases and helps move water through the plant. In this investigation the aquarium water is about 1% salt and 99% water, an Elodea cell normally contains 1% salt and 99% water on the inside, the salt water solution is 6% salt and 94% water, and distilled water is 100% water.

Cells hypotonic to their surrounding solutions cause water to move out of the cell and cause it to shrink. The cell has a smaller number of solutes than the solution outside of the cell membrane. This process can be seen when a plant wilts. In animal cells, the membranes lose shape and support, shrivel up, and die.
