Osmosis can be defined as diffusion of
- A) atoms and molecules through a membrane to an area of higher concentration
- B) water molecules for a dilute solution to a concentrated solution across a permeable membrane
- C) water molecules from area of high concentration to an area of low concentration
- D) water molecules from a dilute solution to a concentrated solution through a semi permeable membrane
Correct Answer: D) water molecules from a dilute solution to a concentrated solution through a semi permeable membrane
Explanation
Osmosis refers to the movement of water molecules from a region of high concentration to a region of low concentration across a semi-permeable membrane. This process is passive and does not require energy. The question is asking us to identify the correct definition of osmosis from the given options. Option A is incorrect because osmosis is specifically the diffusion of water molecules, not atoms and molecules in general. Option B is correct because it describes the movement of water molecules from a dilute solution to a concentrated solution across a semi-permeable membrane. Option C is incorrect because it describes the process of diffusion, not osmosis. Option E is also incorrect because it does not relate to the movement of water molecules across a semi-permeable membrane. Therefore, the correct answer to this question is Option D, which correctly describes the movement of water molecules from a dilute solution to a concentrated solution through a semi-permeable membrane.
