Osmosis In Cells Flashcards
What is an isotonic solution?!
When two solutions have the same concentration
What is a hypertonic solution
The solution that has a greater concentration out of the solutions
What is a hypotonic solution
A solution more dilute than the two solutions.
What happens to accell in a hyptonic solution?
As water moves into the cell by osmosis they swell and could even burst.
What happens to an animal cell in a hypertonic solution?
As water moves out the cell it shrinks and becomes dehydrated
What is turgor pressure in plant cells?
When water can no longer enter the cell due to the pressure inside
What happens when a cell becomes turgid?
The vacuole become turgid
This forced the cytoplasm against the cell membrane and wall
Cell is rigid
What happens when some water leaves a plant cell in a hypertonic solution.
The plant wilts due to the cells becoming flaccid
What shrinks when a plant cell is plasmolysed?
Vacuole
Cyroplasm
Membrane peels from wall
