Write the adaptations seen in plants living in water logged conditions.
A. ) Most plants can aerate their roots by taking in the oxygen through lenticels or through the surface of their root hairs.
2) But plants which have their roots in very wet places, are unable to do this.
3) They are adapted to these water logged conditions by having much larger air spaces which connect the stems with the roots, making diffusion from the upper parts much more efficient.
4) The problem of air transport is more difficult for trees and many not survive with their roots permanently in water.
5) An exception is the mangrove tree of the tropics which sends up aerial roots above the surface and takes in oxygen that way.
