Germination is the process in which a seed or spore emerges from a period of dormancy. The most common example of germination is the sprouting of a seedling from a seed

Feature / In monocots
(GRASSES-corn,barley) / In dicots
(BEANS)
Number of cotyledons (leaves in the seed) / 1 / 2
Arrangement of vascular bundles in the stem / scattered / in ring pattern
Roots / are adventitious / develop from the radicle
Arrangement of major leaf veins / parallel / reticulate
