Germination
Definition:
(n.) The process of germinating; the beginning of vegetation or growth in a seed or plant; the first development of germs, either animal or vegetable.
Example Sentences:
(1) In contrast, in primordial follicles, FSH was restricted to the germ cell but was present in both the oocyte cytoplasm and germinal vesicle.
(2) T cells admixed in the germinal centers were overwhelmingly of the T-helper type.
(3) The lack of TBM prior to germinal center development and their absence in aged mice are inconsistent with the concept that TBM are required for the induction of the germinal center reaction.
