gemma
n. countablen. a small part of a plant or fungus that can break off and grow into a whole new organism. It is a way for some living things to reproduce without seeds.
n. a small cellular body or bud-like structure that detaches from a parent organism to grow into a new individual. This form of asexual reproduction is characteristic of certain fungi, algae, and bryophytes like liverworts.
The liverwort uses a gemma to grow new plants.
Raindrops hitting the cup-like structures splash the gemma out, allowing it to land nearby and start a new colony.
In many species of liverworts, the gemma serves as a primary means of vegetative propagation, ensuring genetic continuity across a specific habitat without the need for sexual spores.
Ultimately from Latin gemma (“jewel”). The given name is mostly borrowed via Italian Gemma; the spelling Jemma in particular is associated with James. Doublet of gemma and gem.
The plural form is 'gemmae'.
