Question

In a test, a teacher collected the answers written by four students as the definition of osmosis as given below. Read carefully and select the correct one.
(a) Movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane.
(b) Movement of solvent molecules from its higher concentration to lower concentration.
(c) Movement of solvent molecules from higher concentration to lower of solution through a
permeable membrane.
(d) Movement of solute molecules from lower concentration to higher concentration of solution through a semipermeable membrane.

Answer 1

Answer:

Explanation:

A .is the corect answer.

Osmosis is the movement of water from a eegion of higher concentration towards a reguon of lower concentration

Answer 2

Answer:

A is a correct answer

Explanation:

Osmosis is the net spontaneous movement of a solvent, such as water, from a higher concentration to a lower concentration across a semipermeable membrane. (option A)

B is incorrect. Because solvent can be moved from a high concentration to a low concentration via a semi-permeable membrane only

C is incorrect because a permeable membrane allows all substances, including solvent and solute, to pass through it.

D is incorrect because osmosis is defined as the net movement of water or a solvent.
