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 freshwater plant if placed in a marine environment?

Answer 1

The plant will lose water to the surrounding environment, become flaccid and eventually wither off.

Step-by-step explanation:

A marine environment is an environment associated with salty water of the sea or ocean.

If a freshwater plant is introduced into a marine environment, the salty water in the environment will become hypertonic to the cells, tissues and organs of the freshwater plant and as a result, the plant will lose water to the surrounding environment due to solute imbalance between the environment and the various cells, tissues, and organs of the freshwater plant.

Consequently, the cells/tissues/organs of the plant become flaccid and eventually wither off.

Answer 2

Answer:it will undergo plasmolysis,shrink and die.

Step-by-step explanation:

The fresh water plant has a high water potential,that is its cystosol will.be of high water concentration compare to its immediate environment ;so it will be in Hypertonic environment of sea water with high solute(salt) potential.

Therefore, the fresh water plant is hypotonic,and therefore loses water from its Cystosol to the hypertonic sea water. This is PLASMOLYSIS.

If this continues ,for a long time the protoplast,is pull from the cell wall and the plant shrinks.
