Plant Biology & Agricultural Sciences

Plant developmental biology is the study of how a single zygotic cell develops into a complex multicellular plant. Development of a full embryo from a zygote; seed germination; creating a mature vegetative plant from an embryo; the generation of flowers, fruits and seeds; and many of the plant's responses to its environment are all covered under "plant evolution". Growth and differentiation of cells, tissues and organs in plants is included as plant development. Plant development and growth is a continuous process. The growth and development of a plant is mainly post-embryonic and new organs are formed throughout its existence. In flowering plants, it includes the mechanisms underlying meristem function during growth and development, cell specification, differentiation, and organogenesis.
