idioplasmic
Adjective (Biology, Historical): - Relating to idioplasm: "idioplasmic" refers to or is characteristic of idioplasm, a term historically used in cell biology to denote the hereditary or germinal part of protoplasm, as distinct from the somatic or nutritive part. It pertains to the substance believed to carry genetic information and determine an organism's inheritable traits.
- (The part of the cell related to inheritance.)
- (The hereditary substance was considered separate.)
- (The idea about hereditary protoplasm.)
Idioplasmic theory: a historical concept in biology that proposed a special substance (idioplasm) within cells responsible for heredity.
- August Weismann's idioplasmic theory suggested that germ cells contain a unique hereditary substance. (A now-outdated biological hypothesis.)
Idioplasmic inheritance: the transmission of traits through idioplasm, as opposed to through the general cytoplasm.
- The debate between idioplasmic and cytoplasmic inheritance was central to early genetics. (A historical controversy in heredity studies.)
Idioplasm (noun): the hypothetical hereditary substance within cells, proposed in 19th-century biology.
- Weismann defined idioplasm as the bearer of hereditary characters. (The theoretical substance.)
Idioplasmic (adjective): alternative spelling or form of "idioplasmic" (identical in meaning).
- The idioplasmic material was thought to be located in the nucleus. (The same concept as idiouplasmic.)
- Germinal: relating to the germ cells or hereditary material.
- Hereditary: passed from parents to offspring.
- This term is largely obsolete in modern biology, having been superseded by concepts like DNA, chromosomes, and germ plasm. It appears mainly in historical texts on the history of genetics or cell theory.
