Solution
The correct option is C Mangroves
Vivipary is a condition where plants produce seeds which germinate before they detach from the parent.
Xerophytes are terrestrial plants which have adapted to survive in environment with little water, like desert or ice covered region. Seeds of such plants are modified to require more water before germination, so to make sure that there is sufficient supply of water for seedling survival. Hence, xerophytes do not show vivipary.
Hydrophytes are plants which are adapted to survive in aquatic conditions.
Such plants show reproductive adaptation-
1. Production of buoyant seeds which can float on high flooded water and delay germination process.
2. Plants grow quickly after germination and form an extended shoot on water surface.
Therefore, hydrophytes do not show vivipary.
Epiphytes are plants which are not rooted in soil but grows on bodies of other plants. But they are not parasites, they produce their own food. Epiphytes show reproductive adaptations as,
1. They produce colorful flowers to attract many pollinators.
2. They also produce strong nectar to lure pollinators.
3. After pollination they produce large number of small seeds which can be dispersed by wind.
But epiphytes do not show vivipary.
Mangroves are various types of trees of medium height which are found in saline coastal habitat. Vivipary is a type of reproductive adaptation shown by mangroves. Mangroves show adaptation to survive in harsh, unstable, dynamic environment, low oxygen and varying salinity of soils. The salinity of the surrounding water and soil damage the seeds. The unstable flood can destroy the seeds. In such environment, if seeds are dispersed in water then their chances of survival are very less. Therefore, mangroves show vivipary.
Therefore, the correct answer is option C.
