Osmosis

osmosis

the net movement of water molecules from a region of high water potential to a region of lower water potential through a partially permeable membrane

dilute solution

area where there are not many water molecules

concentrated solutions

area where there are not many water molecules

water potential gradient

difference in water potential between two areas

name the different solutions

hypertonic

hypotonic

isotonic

hypertonic solution

high solute concentration

less water molecules

hypotonic solution

lower solute concentration

loads of water molecules

isotonic solution

equal solute concentration

no net movement of water

What happens in an animal cell when there’s pure water outside and more concentrated solution inside the cell

water moves into cell via osmosis

cell swells and burst

more concentrated solution outside animal cell, dilute inside cell

water moves out cell via osmosis

cell shrinks

why don’t plant cells burst when placed in pure water

strong cell wall prevents this

what swells when a plant cell is placed in pure water

cytoplasm and vacuole

what does it mean when a plant cell become turgid

right and firm

what happens when a plant cell is placed in a concentration solution

water moves out vacuole and cytoplasm causing them to shrink, cell wall stays firm

what does it mean when a plant cell is flaccid

plant cell is soft, loses firmness and begins to wilt
