WATER POTENTIAL

what is solvation

when a solvent like water surrounds and interacts with solute moelcules or ions

what charge does oxygen have

partial negative

whqt charge does h have

partial positive

how does water solvate the solutes

polar molecules dissolve because of their charges. whatefver charge is positive will be attracted to the negative part of water and vice versa. this breaks it down and forms hydration shells around the molecules in order toi break them do3wn.

how does water move

from LOW to HIGH concentrated solutions

whats hypotonic

where the cell has a higher concentratio n of solutions in it so the outside env has lower solute concentration

whats hypertonic

when cell haslower solute cocnentration

isotonic

both equal conc.

why does osmosis happen

because water likes to move from solutions with h=lower concnetrations of solutes to higher

is the cell membrane permeable to water

yes

whats plasma membrane

thin flexible and control what goes in n out of the cell, made of phospholipids, semi premeable.

whats cell wall

thick rigid freely permeable gives shaoe but diesnt support and doesnt deny entry to anything

what happens w speccial cases like the thingies that always take in water

thry use contractile vacuole to pump out excess water
