How many of the following statements are correct about diffusion in plants?
(A). Diffusion is the movement of substances from higher concentration to lower concentration.
(B). Water always flows from a low water potential area to a higher water potential area.
(C). Diffusion pressure of pure water is more than the diffusion pressure of water in sugar solution.
(D). Diffusion pressure is inversely proportional to the number of diffusing particles.
Choose the correct answer from the options given below:
(A). Diffusion is the movement of substances from higher concentration to lower concentration.
(B). Water always flows from a low water potential area to a higher water potential area.
(C). Diffusion pressure of pure water is more than the diffusion pressure of water in sugar solution.
(D). Diffusion pressure is inversely proportional to the number of diffusing particles.
Choose the correct answer from the options given below:
Options
- A(A), (B) and (D) only.
- B(A) and (C) only.
- C(A), (B), (C) and (D).
- D(B), (C) and (D) only.
Correct answer
B. (A) and (C) only.
Step-by-step solution
Statement (A) is correct. Diffusion is the passive movement of substances from a region of higher concentration to a region of lower concentration.
Statement (B) is incorrect. Water always moves from a region of higher water potential to a region of lower water potential.
Statement (C) is correct. Pure water has the maximum diffusion pressure. The addition of solutes (like sugar) decreases the diffusion pressure of water in the solution.
Statement (D) is incorrect. Diffusion pressure is directly proportional to the concentration or the number of diffusing particles.
Thus, only statements (A) and (C) are correct.
Answer: (A) and (C) only.
Statement (B) is incorrect. Water always moves from a region of higher water potential to a region of lower water potential.
Statement (C) is correct. Pure water has the maximum diffusion pressure. The addition of solutes (like sugar) decreases the diffusion pressure of water in the solution.
Statement (D) is incorrect. Diffusion pressure is directly proportional to the concentration or the number of diffusing particles.
Thus, only statements (A) and (C) are correct.
Answer: (A) and (C) only.
