Question

Which of the following is/are TRUE with regard to water movement in osmosis?

1) hypotonic → hypertonic
2) hypertonic → hypotonic
3) isotonic → hypotonic
4) hypertonic → isotonic
5) both choices C and D

Answer 1

Water moves from hypotonic solutions to hypertonic solutions in osmosis.

Step-by-step explanation:

Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. In osmosis, water moves from hypotonic solutions to hypertonic solutions.

Therefore, the statements 'hypotonic → hypertonic' and 'hypertonic → hypotonic' are both true. Additionally, the statement 'isotonic → hypotonic' is also true, as water will move from an isotonic solution to a hypotonic solution.

In contrast, the statements 'hypertonic → isotonic' and 'both choices C and D' are not true, as these do not describe the movement of water in osmosis.
