Question

A selectively permeable membrane sac filled with water and large molecules of starch is suspended in a beaker of distilled water. what will happen?

Answer 1

A selective permeable membrane sac filled with water and large molecules of starch is suspended in a break of distilled water then water will enter into the sack and it will swell.

This is the process of osmosis in which movement of water molecules form a solution with high concentration to lower concentration till the equilibrium attain. Starch does not pass through thee selectively permeable membrane.Water moves from outside if the cell to the inside leading to swelling of cells.

Small molecules diffuse faster than larger molecules through a membrane. The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute.
