Botany - Morphology of Flowering Plants Question with Solution | TestHub

Mangroves which form shallow littoral forests near sea shores areas are halophytes. Mangrove grow in physiologically dry environment (water is available in plenty but in the form of strong salt solution). These plants develop shallow rootings due to water logged environment where oxygen scarcity prevails. To ensure proper aeration in root system, plants produce respiratory roots or pneumatophores which are negatively geotropic peg-like projections above ground with numerous pores or lenticels for gaseous exchange:
