What are the various stages of germination of seeds?
Answers
The first step in the germination process is the metabolic activation of a dormant seed
>Germination begins with the absorption of water, which causes gibberellin to be produced
>Gibberellin triggers the synthesis of amylase, which breaks down starch into maltose
>Maltose is either hydrolysed (to glucose) for energy, or polymerised (to cellulose) for cell wall formation
>This energy and cellular building blocks is used to promote cell division and the growth of a nascent shoot
Once the seed is metabolically activated, germination proceeds according to the following stages:
>The seed coat (testa) ruptures and the embryonic root (radicle) grows into the ground to extract key nutrients and minerals
>The cotyledon emerges and produces the growing shoot’s first leaves
>The growing plant can be divided into the epicotyl (embryonic shoot), hypocotyl (embryonic stem) and developing roots

Germination is the most important anr final part of the asexual plant reproduction system.
In this germination process,the sapling grows from the seed.
The various stages of a germination process are:
1)In the very first stage ,the seed soaks plenty amount of water or moisture from the soil ,in order to activate the metabolic system inside.
2)Then the root and stem part of the sapling grows from the seed.
3)At last the growth process increases ,in order to make the sapling self-dependent for performing photosynthesis process.
