GERM PLASM Meaning and
Definition
-
Germ plasm refers to the genetic material or the cells that carry genetic information and are responsible for the transmission of hereditary traits from one generation to the next in living organisms. It specifically pertains to the reproductive cells or the gametes, including sperm and egg cells, that contain the genetic information passed on to offspring during sexual reproduction.
In sexually reproducing organisms, germ plasm is crucial as it carries the hereditary material that determines various traits and characteristics, such as physical appearance, behavior, and susceptibility to diseases. These traits are inherited from both parents and are contained within the germ plasm.
The term "germ plasm" was first introduced by the German biologist August Weismann in the late 19th century to describe the specific cells responsible for heredity. Weismann proposed the idea of a "germ plasm theory," which stated that only the germ cells contained the hereditary material and that somatic cells (non-reproductive cells) did not contribute to passing on genetic information to future generations.
Today, the concept of germ plasm is widely accepted in the field of genetics and plays a significant role in understanding inheritance, evolution, and various genetic and reproductive processes across different species. It provides a basis for studying and manipulating genetic traits in plants, animals, and humans through selective breeding or genetic engineering techniques.

The substance in the nuclei of the germinal cells of the ovary and testicle resulting from the duplicative division of the cells of the ovum; by this is meant a division whereby each segment is made up of equal and similar determinants and is thus possessed of the same character and capacity as the ovum itself; the id or part of a germ-cell containing the hereditary principle, idioplasm.

Etymology of GERM PLASM
The term "germ plasm" originates from the German word "keimplasma". It was first introduced by the German biologist August Weismann in the late 19th century. The word "keim" in German means "germ" or "seed", while "plasma" refers to the material or substance of cells. Weismann used this term to describe the hereditary material that is passed down from one generation to another through reproductive cells, such as eggs and sperm. The concept of the germ plasm became an essential part of the early understanding of genetics and inheritance.
