Plants which produce characteristic pneumatophores and show vivipary belong to

Halophyte is the group of plants characterised by pneumatophores and vivipary. As halophytes grow in swampy areas, many roots come out of the ground and grow vertically upwards. These roots are called respiratory roots. Vivipary is the germination of seeds within the fruit so that the plantlet comes out of the plant and falls into the swamp. Seeds cannot germinate in such salty conditions.
(2) Psammophytes are plants adapted to thrive in sandy or desert-like habitats. They possess specific morphological and physiological adaptations, such as deep root systems, reduced leaf surface area, and water-conserving traits, allowing them to withstand arid and sandy conditions.
(3) Hydrophytes are plants adapted to grow in water or aquatic environments, possessing traits like submerged leaves, air-filled tissues, and efficient water absorption mechanisms.
(4) Mesophytes are plants adapted to moderate or average moisture conditions, typically found in environments with balanced water availability, neither too dry nor too wet.
