Explanation:

1. Sugar molecules are polar and relatively large, so they cannot pass directly through the non - polar lipid bilayer without the help of transport proteins.
2. In an isotonic solution, the solute concentration is the same inside and outside the cell. Water molecules still move across the membrane due to random motion, resulting in equal amounts of water flowing into and out of the cell.

Question 1: cannot
Question 2: has water flowing into and out of the cell
