Question

living organisms use osmoregulation to balance solute and water concentrations in their cells, tissues and organs. Many marine organisms have internal solute concentrations that are similar to their environment. However, this is not typically true of freshwater and terrestrial organisms. What is likely to happen to the cells of a marine plant if placed in a freshwater environment? A) The cells will become flaccid. b. The cells will undergo plasmolysis. c. The cells will swell and become turgid. d. There will be no obvious change in the plant cells.

Answer 1

there will be a more negative water potential in the marine organism, so by osmosis the water will move into the cells from the fresh water, causing swelling.

It is c

Answer 2

The cells will swell and become turgid.

Plants found in marine environments are adapted for osmoregulation in hypertonic environments. If you place this kind of plant in freshwater, that will be hypotonic environment and the plant will swell and become turgid.
