The seed germination occurs when the seed receives all the proper conditions like oxygen, temperature, light, water and other nutrients. The seed imbibes water and starts to enlarge and then breaks open. Imbibition is the first step in the germination. Germination causes the resumption of the metabolic activities and the growth of the embryo of seed. As the seed coat break open the radicle emerges first which was followed by the plumule which give rise to the leaves and parts of the stem and further growth occurs resulting in the formation of seedlings. Thus the seeds on germination give rise to young plants called seedlings.
