Tonicity Lab

what type of transport did we observe during this lab?

osmosis (passive transport)

hypertonic solutions

anything above 0.85%: 1%, 2%, 5%

hypotonic solutions

anything below 0.85%: 0.3%, pure distilled water

isotonic solutions

0.85%

hypertonic water flow

water flows out of the cell

hypotonic water flow

water flows into the cell

isotonic water flow

water flows in AND out of the cell equally

hypertonic shape

shriveled (crenated)

hypotonic shape

swell (lyse) and burst

isotonic

biconcave

lower solute concentration outside than inside

into the cell

higher solute concentration outside than inside

out of the cell

equal concentration inside and outside

no movement

Daria’s blood type

hypotonic
