2. Put food coloring in each cup, and then place one potato piece in each cup.

3. After a few minutes, take the potato pieces out and cut them in half.

4. Observe how far the food coloring penetrated the potato pieces, and determine how that relates to surface area and volume.

In the lab, what do the potato pieces represent? What does the food coloring represent?

Answer 1

growth

Answer 2

for the potato,, the potato will grow sprouts

Answer 3

did tht help

Answer 4

@spongebong734 No. This is dealing with osmosis and how size affects the rates in osmotic processes. Further questions?

Answer 5

Yea so what's the answer then? @mrdoldum

Answer 6

The potato could represent anything with a semi-permeable membrane and the experiment looks at how the area of the membrane exposed to a liquid can affect the absolute volume of something moving through the membrane.

So, if we have two gates, one 10 meters wide the other 100 meters wide, and in the 10 m gate in 10 minutes 100 people make it through and in the 100 meters gate 1000 people make it through in 10 minutes what are the rates? Well, the rate of people moving through the gate, if you adjust for the size differences, is the same. Still, because one is much larger than the other more people make it through.
