If a potato cylinder gained weight in a beaker of NaCl, is it

>>8722385
The solution in the beaker around the potato WAS hypertonic, but now they should be isotonic.

If the potato gained weight, then the concentration of NaCl inside the potato was more than the concentration of the solution. Water rushes into the potato cells to balance the concentrations. So the potato is in a hypotonic solution/environment. It's hypertonic to the soln

Thanks, sometimes in biology I feel like I'm doing math and I'm suppose to bilingual because numbers have different values in different languages. . .

Yeah, >>8722403 I'm wrong. This dude is right >>8722404.

I was thinking about cooking stew and thought the salt was absorbed in the potato.

would you say this looks about right? Now it's just me feeling weird saying that h2o molecules went into the starch cells rather than the potato cylinders overall

"Before conducting the test, the idea in mind was that the sodium chloride (NaCl) would merely lack the H2O molecules that would transport into the starch cells of the potato cylinders, but what has become apparent is that we needed to consider the tonicity of the solute that we place the potato cylinders in, as while they did not transport any H2O molecules into the starch cells, they did pull H2O molecules away from the starch cells in the potato cylinders. "

this >>8722404 is me

Nothing is transported or pulling H2O molecules. What is happening is that there is a semi permeable membrane around the potato cells that allows water to flow through (and not ions). The water wants to maintain a constant concentration of NaCl, inside and outside the potato. To do this, water has to go through the cells to decrease the concentration of NaCl since it is higher inside the cell. It pulled water from the solution into the potato's cells
