Question

effect of saltwater encroachment on marsh plants
during a hurricane, salt water invades fresh water marshes causing many of the plants to die and ultimately the loss of soil. the plants are killed because the salt - water solution is __________ to the plants drawing water from the plant cells.
multiple choice
oligotonic
mesotonic
hypertonic
hypotonic
isotonic

Explanation:

In osmosis, water moves from an area of lower solute concentration to an area of higher solute concentration. A hypertonic solution has a higher solute concentration than the plant cells. So water will move out of the plant cells into the salt - water solution, causing the plants to die.

Answer:

C. hypertonic
