The change in shape of cells at the dorsal-most (leading) edge of the epidermis from being polygonal to being elongated in the dorsal/ventral axis. Any process that modulates the surface configuration of a cell. Events that occur at the start of dorsal closure. The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally. The process whose specific outcome is the progression of an embryo from its formation until the end of its embryonic life stage. The end of the embryonic stage is organism-specific. For example, for mammals, the process would begin with zygote formation and end with birth. For insects, the process would begin at zygote formation and end with larval hatching. For plant zygotic embryos, this would be from zygote formation to the end of seed dormancy. For plant vegetative embryos, this would be from the initial determination of the cell or group of cells to form an embryo until the point when the embryo becomes independent of the parent plant. The process by which anatomical structures are generated and organized during the embryonic phase. Morphogenesis pertains to the creation of form. The embryonic phase begins with zygote formation. The end of the embryonic phase is organism-specific. For example, it would be at birth for mammals, larval hatching for insects and seed dormancy in plants. The process by which anatomical structures are generated and organized. Morphogenesis pertains to the creation of form. The increase in size or mass of an anatomical structure that contributes to the structure attaining its shape. The process by which a cell irreversibly increases in size in one [spatial] dimension or along one axis, resulting in the morphogenesis of the cell. Any process that modulates the frequency, rate or extent of embryonic development. The developmental process by which the size or shape of a cell is generated and organized. Morphogenesis pertains to the creation of form. Any process that modulates the surface configuration of an embryonic cell. The process by which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.
