Plant embryogenesis is a crucial process in the development of plant embryos from fertilized ovules, involving cell division, differentiation, and morphogenesis. This process leads to the formation of seeds, which play a vital role in the plant life cycle. The stages of embryo formation, structure,

The first week of development after ovulation involves key processes like fertilization, cleavage, and blastocyst formation. It begins with the maturation of the primary oocyte in the follicle, leading to ovulation and potential fertilization. During this period, hormonal changes in the ovarian cycl

Plant tissue culture techniques such as Organogenesis and Somatic Embryogenesis play a crucial role in regenerating whole plants from meristem cells. The process involves the formation of organs directly from explants or callus structures and the production of adventitious organs like roots, shoots,

Formation of the gut tube during embryogenesis involves cephalocaudal and lateral folding of the embryo, resulting in the development of the foregut, midgut, and hindgut. The yolk sac and the allantois play key roles in the formation of the primitive gut. As the embryo develops, the vitelline duct a
