DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water moves through a cell membranes from areas of ____ concentration to areas of ____ concentration.
A
low to high
B
high to low
C
equal to low
D
equal to equal
Explanation: 

Detailed explanation-1: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

Detailed explanation-2: -In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Diffusion can occur in any mixture, including one that includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.

Detailed explanation-3: -Osmosis refers to the movement of fluid across a membrane in response to differing concentrations of solutes on the two sides of the membrane.

Detailed explanation-4: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.

Detailed explanation-5: -The movement of water molecule from a region of higher concentration to a region of its lower concentration through a semi permeable membrane is called Osmosis.
