Osmosis
1. What is Osmosis?
Answer:
Osmosis is the process of spontaneous movement of solvent molecules, usually water, across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
2. What is the Significance of Osmosis in biology?
Answer:
Osmosis is vital for biological processes such as maintaining cell turgor pressure, nutrient uptake in plant roots, and regulating cell volume.
3. What is an Example of Osmosis?
Answer:
One common example is when raisins or grapes placed in a concentrated sugar solution swell as water from the fruit moves into the solution through osmosis.
4. What is Reverse Osmosis?
Answer:
Reverse osmosis is a process that uses pressure to force solvent molecules through a semipermeable membrane, effectively removing solutes and purifying the solvent. It’s used in water purification and desalination.
5. What is the Difference between Osmosis and Diffusion?
Answer:
Osmosis is a specific type of diffusion involving solvent molecules through a semipermeable membrane, while diffusion encompasses the movement of particles (solutes or gases) in any medium, often without a membrane.
Osmosis
Osmosis is a biological and chemical process in which there is passive movement of solvent molecules from a region of lower solute concentration to a region of higher solute concentration through a semipermeable membrane, thus equalizing solute concentrations on both sides of the membrane. The osmosis process is essential for many biological processes, including the absorption of nutrients and the maintenance of the fluid balance in cells and organisms.
