Question

Differentiate between germination and vivipary.

Answer 1

Hint: Seed plants spread their seeds in the environment. When the conditions are favourable, these seeds start to germinate and produce seedlings, which can later grow to become mature plants. We call this process germination; it is a vital process in the development of plants. Generally, seeds undergo germination after detachment from the parent plant. However, some seeds or embryos start developing before detachment from the parent plant, and this process is called vivipary.

Complete solution:
Differences between germination and vivipary are as follows:

Germination	Vivipary
Germination is the emergence of a seedling from a seed under favourable conditions. The seedling further develops into a mature plant.	Vivipary refers to the premature germination of seed and the development of embryos within the fruit, while it is still attached to the parent plant.
Usually occurs externally from the dropped seeds.	Seeds germinate inside the fruit and come out through the fruit wall.
It occurs after detachment from the parent plant.	It occurs while attached to the parent plant.
Resources from the parent plant are not required.	Resources from the parent plant are required.
Developing embryos derives nutrition from the cotyledon.	Developing embryos derives nutrition from the fruit.
Some of the examples are bean seed, maize grain	Some of the examples are Rhizophora, Sonneratia

Note:
Seeds possess a hormone that suppresses the process of germination. This is a necessity, as it protects the seeds from germinating when conditions are unfavourable and missing their shot to become plants. But sometimes that hormone runs out, like when a tomato is kept on a table for too long. And sometimes the hormone can be tricked into thinking that the available conditions are favourable, especially if the environment is warm and moist.
