Which of these is the definition of OSMOSIS?
A
The movement of water molecules from a region of higher solution to a region of lower solution through a partially permeable membrane
B
The net movement of water molecules from a region of higher water potential (concentrated solution) to a region of lower water potential (dilute solution) through a partially permeable membrane
C
The net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution)
D
The net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution) through a partially permeable membrane
Explanation: 

Detailed explanation-1: -Final answer: Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

Detailed explanation-2: -Introduction. In physiology, osmosis (Greek for push) is the net movement of water across a semipermeable membrane.[1][2] Across this membrane, water will tend to move from an area of high concentration to an area of low concentration.

Detailed explanation-3: -Osmosis is the net movement of water molecules across a semi-permeable membrane, from an area of low solute (high water activity) concentration to higher solute concentration (lower water activity). Water molecules want to balance the solute concentration on either side of the membrane to a more isotonic state.
