The life cycle is also called the development cycle and describes the course of development of an organism. The cycle begins with the fertilization of the egg or the seed of plants and ends with the production of a germ cell through the adult (adult ) form from which a new organism is produced. There are written at different stages of development.

In animals: (affects vertebrates and invertebrates) Fertilization - cleavage divisions - gastrulation - neurulation - Organogenesis - metamorphosis (for some ) - adult animal (from here the cycle starts all over again )

In plants: Gametogenesis and fertilization - embryo genesis - germination - growth and maturation ( cycle begins again )

The knowledge of various development processes derived from specific organisms, the model organisms.
