What is osmosis?write factors affecting it
Answers
Osmosis:-
Osmosis is the passage of water from a high solute concentration area through a semi permeable membrane to a low solute concentration area to equalize the solute concentrations on both sides.
Factors Affecting the Rate of Osmosis:-
Temperature -> The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.
Surface Area -> The larger surface area for the molecules to move easily across but the smaller the area, the more restricted the movements of the molecules and the slower the movement.
Difference in Water Potential –> The higher, the difference in water potential, the faster the osmosis but for the lesser water molecules are in the region of low concentration, more water molecules from the region of higher concentration can enter faster and easier.
Pressure –> The more pressure, the molecules will move faster because they are being pushed faster across a low concentration.
Concentration gradient -> The movement of osmosis is affected by the concentration gradient but the lower concentration of the solute within a solvent, the faster osmosis will occur in that solvent.
Light and dark –> They are also factors of osmosis; since the brighter light, the osmosis takes place faster.
