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?

Answer 1

The Cell will burst or swell due to the large amount of water enters in plan call.

Step-by-step explanation:

• The marine plant cell is hypertonic compared with fresh water.
• So water will enters the cell trough osmosis.
• Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
• The cell will swell because large quantity of water enters the cell.

Answer 2

If the marine plant is placed in a freshwater environment, then the cells will undergo plasmolysis.

The plants found in the freshwater surroundings are adjusted for osmoregulation in hypotonic environments. If one place this type of plant in a marine environment, that is, one with a greater concentration of dissolved salts, then the environment is considered as hypertonic environment. The cells of the plant will lose water and will go through the process of plasmolysis.
