Question

Movement of water through semipermeable membrane produces
A) Wall pressure
B) Suction pressure
C) Osmotic pressure
D) Turgor pressure

Answer 1

Hint: Semi -permeable membrane does not allow the larger molecules to pass through and allows only the dissolved molecules, water and other substances to pass through the concentration gradient. The process by which water molecules diffuse through higher water concentration to lower water concentration.

Complete answer:
INTRODUCTION :
Osmosis is a type of diffusion. It is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential. It is a passive process by net movement of water molecules through semi permeability. It is an important process of cells for movement of molecules in and out of the cell.
A) WALL PRESSURE : Wall pressure is referred to as hydrostatic pressure. The pressure exerted on the contents of a plant cell by the cell wall for movement of molecules.
B) SUCTION PRESSURE : Suction pressure is referred to as a diffusion pressure deficit. It has the ability of plant cells to absorb water.
C) OSMOTIC PRESSURE: Osmosis is a process of movement of molecules through a semipermeable membrane from a region of lower solute concentration to higher solute concentration. Osmosis process is important in stabilizing the internal environment of the organism by balancing the level of molecules.
D) TURGOR PRESSURE: Turgor pressure is a kind of hydrostatic pressure , this occurs only within the plant cell. The pressure in the cell pushes the cell wall outward by pushing the water inside the cell wall outward.

Thus, the correct answer is C) Osmotic pressure.

Note :
Osmosis is a process by which dissolved molecules pass through a semi membrane ,in this process the molecules move from lower to higher concentration. In the diffusion process the molecules do not pass through the semipermeable membrane, in this process the molecules move from higher concentration to lower concentration.
