Question

Mangrove plants show vivipary. This is

• A. Germination of seeds with in fruits while still attached to parent plant
• B. Germination of seeds in fruits on the soil
• C. Germination of seeds within fruit on sterile artificial culture medium
• D. Germination of seeds only after dispersal of fruits

Answer 1

The correct option is A Germination of seeds with in fruits while still attached to parent plant

The mangroves grow as a group of shrubs along the tidal coasts of mudflats, with specially evolved viviparous (bringing forth live young) seed development just like mammals. In mangroves, Abscisic acid(ABA) a plant hormone plays a significant role in viviparous germination of seeds.

The plant hormone leads to transduction followed by the MAPK signaling pathway.

Vivipary is a condition whereby the embryo(the young plant within the seed) grows first to break through the seed coat out of the fruit while still attached to the parent plant.

So, the correct answer is 'Germination of seeds within fruits while still attached to the parent plant'
