Question

Can someone please explain the direction of osmosis like how to know if inside the cell is hypotonic or hypertonic and how the outside environment is

Answer 1

Osmosis is the net flow of solvent through a semipermeable membrane. The direction of net solvent flow is always from the side with the lower concentration of solute to the side with the higher concentration. This means that water flows from the solution with the lower solute concentration into the solution with higher solute concentration.

Step-by-step explanation:

If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

If a cell is placed in a hypotonic solution, there will be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
