What is Osmosis? What are isotonic solutions? Write the biological
importance of osmotic pressure.
Answers
Answer:
An animal cell survives only in anisotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop. Theosmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute.
Answer:
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Isotonic solution: A solution that has the same salt concentration as cells and blood. Isotonic solutions are commonly used as intravenously infused fluids in hospitalized patients.

Osmotic pressure is of vital importance in biology as the cell's membrane is selective toward many of the solutes found in living organisms. When a cell is placed in a hypertonic solution, water actually flows out of the cell into the surrounding solution thereby causing the cells to shrink and lose its turgidity
