A solution of sucrose and starch

A solution of sucrose and starch is placed into a dialysis bag and the bag is then placed in a beaker with dilute iodine and water.

question:
the sugar is small enough to pas the bag's membrane. over time, sugar should be detectable____
outside the bag
inside the bag
both outside and inside the bag

I thought the answer was inside the bag only because I thought that when it comes to hypertonic and hypo tonic solutions it was water that moved from higher concentration to lower, but I'm not positive.
Am I right? If I'm wring could someone please explain?

The above answer by "t y" is confused.
Starch is NOT sugar; it is made of sugar molecules (glucoses) all hooked together.
But a starch molecule is definitely NOT a sugar molecule.

The point here is that sucrose molecules can (and therefore, will) move through the dialysis membrane, but starch is too large.

Hypertonic and hypotonic have to do only with the diffusion of water,
not with the diffusion of sugar or starch.
EVERYTHING that is in solution is moving randomly all the time,
and so will spread out according to ITS OWN concentration gradient.
Water will undoubtedly diffuse into the bag in this experiment.
But the question is not about the water, or even the starch.
The question is about the sucrose, and IT will diffuse out of the bag.
Once some sucrose molecules are outside, some will randomly move back in,
but until equilibrium is reached, more will move out than in.
At equilibrium, there will be equal concentrations of sucrose inside and outside the bag.

So very soon after this dialysis bag is immersed in the water,
sucrose will be detectable outside the bag.
And of course, it will always be detectable inside the bag, as well.
