OVUM SEGMENTATION STAGE Meaning and
Definition
-
Ovum segmentation stage refers to a specific developmental period during the reproduction process of certain organisms, particularly invertebrates and lower vertebrates, where the fertilized egg undergoes a series of cell divisions or segmentations to form a multicellular structure known as a blastula.
During the ovum segmentation stage, the fertilized ovum, also called the zygote, begins to divide into smaller cells. These divisions occur through a process called mitosis, whereby the genetic material is replicated and distributed equally between daughter cells. The segmentation is often symmetrical, resulting in the formation of identical cells.
As the ovum undergoes continuous divisions, the cells formed gradually form a hollow ball-shaped structure called a blastula. The blastula consists of an outer layer of cells known as the blastoderm and an inner fluid-filled cavity called the blastocoel. The blastula is a crucial stage in embryonic development, as it sets the foundation for further differentiation and specialization of cells into various tissues and organs.
The ovum segmentation stage typically occurs shortly after fertilization and precedes the gastrulation stage, where the blastula undergoes complex rearrangements to form layers and establish the basic body plan of the organism.
Overall, the ovum segmentation stage represents a critical period in embryonic development, laying the groundwork for subsequent growth and morphogenesis.
