In Biology we have been studying the movement in and out the cells. Today experiment consisted on cutting strips of potatoes and soaking them in distilled water and a concentrated solution for 24 hours. Then we took another strip of potatoe that was not soaked in anything and then compared them. I work with Flor Araya and Rochi Hartmann. This are our results.

Potatoe in distilled water: This was the stiffest and least flexible potato because it absorbed water, therefore it swelled and became firm.

Natural potato: This potato was less stiff but more flexible than the one soaked in distilled water.

Potato in concentrated solution: This was the least stiff one of all and the most flexible.
