Concept:Vivipary is a type of germination where the seed germinates while still attached to the parent plant. The embryo grows and emerges from the seed before detachment.Explanation:In viviparous germination, the ovule is fertilised on the parent tree. The embryo continues to grow, pierces the seed coat, and remains attached to the mother plant. This is common in many mangrove species. Rhizophora is a clear example of vivipary. Mango, potato, and sugarcane do not show viviparous germination.Difference between normal germination and vivipary:
Germination
Vivipary
The embryo of the seed becomes activated and begins to grow into a new plant.
The germination of seed within the fruit, while it is still attached to the parent plant.
