Water diffusing with the concentration gradient from high water concentration to low water concentration across a cell membrane is ____
A
Facilitated Diffusion
B
Simple Diffusion
C
Active Transport
D
Osmosis
Explanation: 

Detailed explanation-1: -Osmosis is the movement of water molecules from a region of high water potential to a region of lower water potential across a semipermeable membrane. Water moves from its higher concentration to its lower concentration through a semipermeable membrane.

Detailed explanation-2: -In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.

Detailed explanation-3: -Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.

Detailed explanation-4: -Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

Detailed explanation-5: -The hypertonic solution has a lower water concentration than the hypotonic solution, so a concentration gradient of water now exists across the membrane. Water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic.
