During a practical exercise, a student placed a piece of fresh yam in a concentrated salt solution and observed that it became flaccid after 30 minutes. Which of the following best explains this observation?

Question

Accepted Answer

Water moved from the yam cells into the solution by osmosis because the solution had a lower water potential. A concentrated salt solution has a lower (more negative) water potential than the yam cells, so water moves out of the cells into the surrounding solution by osmosis. This loss of water causes the cells to lose turgor pressure and become flaccid, a process called plasmolysis. Option C incorrectly st

Answer

A) Water moved from the yam cells into the solution by osmosis because the solution had a lower water potential

Answer

B) Salt ions moved into the yam cells by active transport, causing them to shrink

Answer

C) Water moved from the solution into the yam cells because the cells had a lower solute concentration

Answer

D) The yam cells absorbed salt by diffusion, increasing their internal pressure
