Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of ____
A
osmosis
B
equilibrium
C
diffusion
D
hypertonic
Explanation: 

Detailed explanation-1: -If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

Detailed explanation-2: -Osmotic equilibrium occurs when the fraction of water molecules in solution matches the fraction of pure water molecules that have enough energy to overcome the pressure difference.

Detailed explanation-3: -The osmosis will continue until both side of the membrane have the same concentration (same free energy). This is the equilibrium state.
