HOLOBLASTIC Meaning and Definition

1. Holoblastic is an adjective used in embryology and developmental biology to describe a type of cell division that occurs during early stages of embryonic development. The term "holoblastic" is derived from the Greek words "holos," meaning whole or complete, and "blastos," meaning bud or germ. In this context, it refers to the complete division of cells.

   During holoblastic cell division, the entire fertilized egg or zygote undergoes repeated mitotic divisions without the formation of any cleavage furrows or partial divisions. This process leads to the development of multiple daughter cells that are roughly equal in size and have a complete set of genetic information. As a result, holoblastic division tends to occur in larger, non-yolk-laden eggs.

   Holoblastic division can take place either radially or bilaterally, depending on the orientation of the cell division plane. Radial holoblastic division occurs when cells divide symmetrically around the central axis of the zygote, leading to the formation of a sphere or disc-like structure. Bilateral holoblastic division, on the other hand, occurs when the division plane is perpendicular to the central axis, dividing the zygote into two equal halves.

   Overall, the term "holoblastic" describes a complete and uniform cell division that occurs in the early stages of embryonic development. Its significance lies in the formation of daughter cells with equal genetic information, which is essential for the subsequent formation of tissues, organs, and ultimately the complete organism.

2. Denoting the involvement of the entire (alecithal or moderately telolecithal) ovum in segmentation.

Etymology of HOLOBLASTIC

The word "holoblastic" comes from the combination of two ancient Greek words.

The first part, "holos" (ὅλος), means "whole" or "entire".

The second part, "blastos" (βλαστός), means "bud" or "germ".

Therefore, "holoblastic" refers to a process or pattern of cell division where the entire embryo or egg is divided into separate cells without leaving any part undivided.
