Question

.Differentiate between 1. Diffusion and osmosi​

Answer 1

Explanation:

hlo mate here's your answer

Definition of Osmosis

Osmosis refers to a type of diffusion in which a substance crosses a semipermeable membrane so as to balance the concentrations of another substance. Furthermore, in the field of biology, it happens when a solvent such as water flows into a cell or out of it on the basis of a solute’s concentration like salt. Also, the occurrence of osmosis takes place spontaneously without any use of cell energy.

Definition of Diffusion

Diffusion can be defined as a physical process that refers to the net movement of molecules from a region of high concentration to a lower concentration region. This definition certainly makes the difference between osmosis and diffusion more clear. Furthermore, the material that diffuses could be of any state of matter-solid, liquid, or gas.

Answer 2

Answer:

OsmosisDiffusionIt happens only in the liquid state.It occurs in all states of matter i.e., solids, liquids or gases.It should be movement of only water or solvent through semipermeable membrane from lower concentration to higher concentration.Any type of substance that moves from higher concentration area to lower concentration area.It is applied only for the solvent part of the solution.Diffusion is applied to all states of matter.

 

It requires semipermeable membrane.This phenomenon does not require semipermeable membrane.Osmosis depends on the rate of reduction of free energy of one solvent.It only depends on the free energy of the substance.Influenced by the solute potentialNot influenced by solute potentialIt is opposed by hydrostatic or turgor pressure.Hydrostatic pressure or turgor pressure will not occur in diffusion.In this process, concentration of solvent is not equalized.Concentration of whole substance will be equalized.Factors like solute potential, water potential and pressure potential will not affect osmosis.Factors like solute potential, water potential and pressure potential will not affect diffusion.
