Answer 1

Germination occurs in following stages:

• The seeds absorb water through the seed hole. The cells of the embryo start dividing and increasing in size.
• The seed coat breaks open and the root (radical) sprout and grows downwards.
• Then the shoot ( plumule) start growing upwards, which later produces stem and leaves.
• When the seedling grows green leaves, it starts making its own food.
• By this time, cotyledons dry up and fall. The seedling then develops into a new plant.
