Land plants die if their roots remain waterlogged.

उत्तर
Older portions of the root do not have root hairs. They are covered with a protective layer of dead calls having tiny openings called lenticels. Through these lenticels, gaseous exchange occurs between the soil and inner living cells. If the roots of land plants remain waterlogged, then lenticels will not be able to do the gaseous exchange and as a result of this plants will die.
