gemmule

noun ˈdʒɛmjuːlˈdʒɛmjul

Zoology

A tough-coated dormant cluster of embryonic cells produced by a freshwater sponge for development in more favourable conditions.
Example sentencesExamples
- Dendrites branch repeatedly, and their surfaces are studded with spines or gemmules, thus expanding the receptive cell surface.
- Methods of asexual reproduction include both budding and the formation of gemmules.
- Some species also form internal buds, called gemmules, which can survive extremely unfavorable conditions that cause the rest of the sponge to die.
- These gemmules circulate throughout the body, and each sex cell eventually accumulates a full set.
- Development consisted of the orderly assembly and expression of the gemmules transmitted via the parental germ cells to the progeny.

Derivatives

gemmulation

noun

Zoology

In cold regions, gemmulation occurs in winter, and the inactive gemmules are said to hibernate; in warm regions, gemmulation occurs in summer, and the gemmules are said to estivate.
Example sentencesExamples
- In his description of the new species, he reported that the fungus appeared in the tissues as spherical to ovoid cells, measuring 3 to 30 µm in diameter, with multiple buds or simple gemmulation.

Origin

Mid 19th century: from French, from Latin gemmula, diminutive of gemma 'bud, jewel'.
