Phoneticsgem·ma

US/ˈdʒɛmə/

UK/dʒˈɛmɐ/

Definition

n. 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.

Examples

“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.”
