If a 5% glucose solution (a) is separated from a 10% glucose solution (b) by a semipermeable membrane, glucose will diffuse from to and water will diffuse from to

Glucose will diffuse from Solution B to Solution A. (B has higher concentration of glucose)

Water will diffuse from Solution A to Solution B.
(A has lower concentration of glucose, thus higher water potential than B)

Both prokaryotic and eukaryotic cells have ribosomes and cell membranes
