Seed germination can be defined as the growth of a seed into a young plant (seedling).
The Process of Seed Germination
1.Water imbibition: When environmental conditions are optimal (favorable), germination is initiated by the
absorbtion of water by seed which induces swelling of the seed until it splits open.
1.Root and Shoot formation: Once the seed has ruptured, the radicle (primary root) and plumule (shoot) can
emerge from the seed. This process is initiated by specific enzymes that become activated when the seed is
exposed to water. The roots grow downwards, and the shoot grows upwards towards the soil surface.
1.A seedling is formed: Once the shoot emerges from the soil surface, the cotyledons become fully unfolded
and expand, eventually forming the first leaves and is considered a seedling.
