Solution
The correct option is D X - Pressure gradient; Y - Concentration gradient
Osmosis occurs in response to a driving force. The net direction and the rate of osmosis depend on both the pressure gradient and concentration gradient.
Solute potential also known as osmostic potential, it is the decrease in water potential due to dissolved substances or solute in a solution. Decrease in solute potential is with increase solute concentration which means lower water potential. Water moves from the region of higher solute potential to a region of lower solute potential.
Pressure potential also called turgor pressure is the pressure exerted by the cell membrane on cell wall. Movement of water from higher pressure potential to lower pressure potential takes place.
Matric potential is the quantum change in water potential in hydrophilic substances. This is not seen in living systems. It causes imbibing substances to adsorb more water molecules.
Water potential is the difference between the free energy of water molecules in pure water and the energy of water in a solution.
Difference in hydrostatic pressure across either side of a membrane is known as pressure gradient.
The factors involved in the movement of water through osmosis are solute potential, pressure potential, water potential, pressure gradient and concentration gradient.
