Question

Describe diffusion and osmosis, as well as comparing hypotonic, hypertonic and isotonic solutions.

Answer 1

Answer:

Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.

Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.

A hypotonic solution is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.

A hypertonic solution is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.

An isotonic solution where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
