Question

1. Define osmosis. Graph it.
2. Define active transport. Graph it.

Answer 1

Osmosis is the movement of solvent molecules along the concentration gradient, that is, from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane. This process does not require any ATP molecules and carrier proteins.

Active transport is the movement of molecules against the concentration gradient, that is, from region of lower concentration to a region of higher concentration. It requires energy in the form of ATP and also requires carrier proteins located on the membrane.
