ANATOMY

Detailed explanation-1: -iii) The size of the cell remains the same when placed in an isotonic solution. This is because both the inside and outside of the cell are in the same concentration with respect to water and solutes Hence, there there will be no net movement of water.

Detailed explanation-2: -When a red blood cell is placed in an isotonic solution, there will be no net movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly; therefore, there will be no net movement of water towards the solution or the cell.

Detailed explanation-3: -Osmosis is the concept that involves the moment of water molecules inside and outside of the cell. Isotonic solution is the one in which the concentration of solute and water molecules are in equilibrium. If the cell is placed in isotonic solution the net change will be zero. So, the cells retain their size.

Detailed explanation-4: -In an isotonic environment, there is the same amount of water on each side, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-5: -The isotonic solution allow the cells to move water and nutrients in and out of the cells. This is necessary for blood cells to perform their function of delivering oxygen and other nutrients to other parts of the body.
