BLASTULE Meaning and
Definition
-
A blastule, also known as a blastula, is a stage in embryonic development of certain animals, particularly during the early stages of animal development. It is a hollow ball of cells that forms after the morula stage, which is formed by successive cell divisions of the zygote. The blastule is characterized by a single layer of cells known as the blastoderm or blastodermic wall, which encloses a central cavity called the blastocoele.
The formation of the blastule is part of a process known as blastulation, which occurs in animals with radial symmetry such as sponges, flatworms, and most notably invertebrate and vertebrate embryos. This process is crucial as it marks the transition from a solid mass of cells to the establishment of germ layers, which will eventually give rise to the various tissues and organs of the developing embryo.
The blastule stage is important for the further development of the embryo, as it serves as the starting point for the next stages of embryogenesis. In some animals, the blastule undergoes gastrulation, a process in which the blastule folds and forms the different germ layers. This marks the onset of organogenesis and the formation of more complex structures within the embryo.
Overall, the blastule is a critical stage in the early development of animals, representing an important transition from a mass of undifferentiated cells to the establishment of organized tissues and organs.
