Which of the following is associated with the development of a fertilized ovum?

The development of a fertilized ovum involves several stages, and blastomeres are critical to this process. After fertilization, the zygote undergoes a series of mitotic divisions, known as cleavage, which results in the formation of smaller cells called blastomeres. These cells are formed as the original zygote divides but remain surrounded by the same outer membrane. The formation of blastomeres marks the transition from a single fertilized ovum to a multicellular structure, ultimately leading to the morula and then the blastocyst stage.

At this early stage of development, each blastomere retains the potential to develop into an entire embryo, making them vital in the context of embryogenesis. The subsequent arrangement and differentiation of these blastomeres will continue to play a crucial role in the formation of the structures that will support the embryo’s growth.

The blastocele is the fluid-filled cavity that forms within the blastocyst but does not refer to the embryo itself or the early stages of cell division. The morula is a later stage that results from the continued division of the blastomeres, and the cleavage furrow is a temporary structure that appears during cell division, specifically during cytokinesis, but does not relate directly
