questions about hypertonic hypotonic

Postby mariahg777 » Sun Jul 06, 2008 10:21 pm

and isotonic.

I am taking a biology class in college after not taking biology for over 15 years...I am having a hard time understanding the hypo.hyper and isotonic...

I know water always moves from hypo to hyper but I don't get what they are and what they really mean...someone please help me.

It's a comparison of how watery two areas are - in solutions that are water and "other stuff." The reason water moves is basic diffusion - it tend to spread from where there's more (the more dilute hypotonic) to where there's less (the less dilute hypertonic).

hypo- = under
hyper- = over
iso- = similar
tonus = tone -- tonic (adj.)

Water flows from hypotonic solution to hypertonic solution, as osmosis a.k.a water diffusion, to create isotonic solutions on both side (balance).

hi
well dont worry ... it is so easy idea :
hypotonic solution is the solution in which the solvent concentration ( example : salt ) in the solution is very little ( comparing to the concentration of the salt in the living cells) , hypo = less . in this case when you place a blood cell in this solution ( for example ) the fliuds well move from the blood cell ( which will be concederd as a hypertonic if you like) ... to the solution ...... the cell then well keep shrinking tel it dies ,,,,,,

hypertonic solution have a higher salt concentration than a living cell have si if you place a red blood cell there the water will move from the solution to the blood cell which will keep swallowing tell it dies ....

the iso tonic solution is a balanced solution where the concentration of salt is almost exactely the same of living cells so there will be no movement of the water when you place any cell in it ..... so cells will live ....

i hope o could explain it well to you ... i will try to add pictures also
