Assertion :Many mangrove plants possess high levels of organic solutes.
Reason: This is an adaptation to cope with the conditions of high salt concentration and osmotic potential.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Mangroves are found
in marshy conditions of tropical deltas and along ocean edges. For
coping with conditions of high salt concentration and osmotic
potential, many mangrove plants have high levels of organic solutes,
such as proline and sorbitol. Dunaliella species (green and
halophytic algae found in hyper saline lakes) can tolerate saline
conditions by accumulating glycerol in the cells, which helps in
osmoregulation. Some species of mangroves can excrete salts through
the salt glands on the leaves. Some mangroves can exclude salts from
the roots by pumping excess salts back into soil. So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
