Deuteroplasma [Deuteroplasma, Lne; Deutero- + (Cyto)Plasma; Syn.: Detoplasm, Yolk, Paraplasm]

Deuteroplasm is a collection of trophic inclusions that are located in the cytoplasm of the egg. These inclusions are necessary for the development and growth of the embryo in the egg.

Deuteroplasm is made up of many different components, including yolk and paraplasm. The yolk is the main source of nutrients for the embryo, and the paraplasm contains proteins, fats and carbohydrates.

The yolk is formed by cell division of the egg and migration of yolk cells to the center of the egg. Paraplasm is formed from the cytoplasm of the egg after fertilization.

The importance of deuteroplasm is that it provides the embryo with essential nutrients in the early stages of development. If the yolk or paraplasm is missing or damaged, this can lead to disruption of the development of the embryo and its death.

Thus, deuteroplasm is a key component of the egg and plays an important role in the development of the embryo.
