Question

Vivipary is a special adaptation in mangrove plant.

Answer 1

Vivipary is the phenomenon of reproduction via buds or seedlings, such as shoots or bulbil. Seedlings that are germinated remains attached to the parent plant and are detached when ready to establish themselves in the substrate. Viviparous plants produce embryos that develop before they detach from the parent plant. It is a type of asexual vegetative reproduction. Common examples of viviparous plants include Bruguiera, Ceriops, Kandelia and Rhizophora species. Vivipary is a special adaptation in mangrove plants. Seedlings of some mangrove plants are dispersed by currents if drop into the water. However, in others, they develop a heavy, straight taproot that penetrates into the mud after dropping. Hence, in this mangrove plantlets are true seedlings produced by sexual reproduction unlike other viviparous seedlings produced by asexual reproduction. They disperse seedlings via water with varying degrees of vivipary while the propagule is attached to the parent tree.
