gemmule Meaning
gemmule (n)
the physically discrete element that Darwin proposed as responsible for heredity
gemmule (n.)
A little leaf bud, as the plumule between the cotyledons.
One of the buds of mosses.
One of the reproductive spores of algae.
An ovule.
A bud produced in generation by gemmation.
One of the imaginary granules or atoms which, according to Darwin's hypothesis of pangenesis, are continually being thrown off from every cell or unit, and circulate freely throughout the system, and when supplied with proper nutriment multiply by self-division and ultimately develop into cells like those from which they were derived. They are supposed to be transmitted from the parent to the offspring, but are often transmitted in a dormant state during many generations and are then developed. See Pangenesis.
gemmule Sentence Examples
- The freshwater sponge possesses unique gemmules that enable its survival in harsh environmental conditions.
- The gemmule acts as a dormant stage, protecting the sponge's cells during unfavorable conditions.
- Within the gemmule, a group of specialized cells, called archaeocytes, remain dormant until conditions become favorable.
- As environmental cues trigger germination, the archaeocytes within the gemmule become active and initiate cell division.
- The gemmule's outer layer weakens, allowing the internal cells to emerge and form a new sponge.
- Gemmules are essential for asexual reproduction in freshwater sponges, enabling them to colonize new environments.
- The dispersal of gemmules by water currents or animals increases the sponge's genetic diversity.
- The gemmule's dormant state provides protection against predators, environmental fluctuations, and desiccation.
- Researchers study gemmules to understand the evolutionary adaptations and resilience of freshwater sponges.
- The presence of gemmules in the sediment layers of aquatic ecosystems provides valuable insights into past sponge populations and environmental conditions.
