DEUTEROPLASM Meaning and
Definition
-
Deuteroplasm refers to the reserve material present in the egg of an organism that is used for the nourishment of the developing embryo during its early stages of development. It is a term commonly used in the field of embryology, particularly in the context of oogenesis (egg production).
Deuteroplasm is derived from the Greek word "deuteros," meaning second, and "plasma," meaning substance. It serves as a vital energy source for the growing embryo until it becomes capable of sustaining itself. Typically, this reserve material is stored in the form of yolk granules or yolk droplets within the egg cytoplasm.
The quantity and distribution of deuteroplasm vary across different species, depending on their reproductive strategies. Organisms that lay eggs with a large amount of deuteroplasm are known as macrolecithal, whereas those with small amounts are called microlecithal. The presence of deuteroplasm also influences the mechanism of embryonic development, as it determines the egg polarity and facilitates the process of cell division and differentiation.
In addition to providing nutrition, deuteroplasm can also contain other essential substances such as vitamins, minerals, proteins, and lipids. These nutrients play a crucial role in supporting the rapid growth and development of the embryo. As development progresses, the deuteroplasm gradually becomes depleted or consumed, and the embryo starts relying on external sources for sustenance.
Overall, deuteroplasm serves as a vital component in the early stages of embryonic development, ensuring the provision of nourishment and facilitating the formation of complex structures in the developing organism.

Etymology of DEUTEROPLASM
The word "deuteroplasm" is derived from two ancient Greek roots: "deutero" meaning "second" or "secondary", and "plasma" referring to "something molded" or "a formative substance". In biology, "plasm" also refers to the fluid part of a cell, thus "deuteroplasm" can be understood as the secondary or accessory part of the cell.
