Do liverworts have gemma cups?
Most liverworts can reproduce asexually by means of gemmae, which are disks of tissues produced by the gametophytic generation. The gemmae are held in special organs known as gemma cups and are dispersed by rainfall. Fragmentation of the thallus can also result in new plants.
What is the function of the gemma Cups in liverworts?
The main function of the Gemma cup is vegetative reproduction. The Gemma is a small cup-shaped cell found on the thalli of bryophytes such as mosses and liverworts. The Gemma cells separated from the parent and develop into a new individual.
What plant do gemma cups form?
The basal land plant Marchantia polymorpha efficiently propagates in favourable environments through clonal progeny called gemmae. Gemmae develop in cup-shaped receptacles known as gemma cups, which are formed on the gametophyte body.
What is a gemma Cup?
Definition. A small receptacle or cup on upper surface of bryophytes in which gemmae are produced from which they are splashed out of and dispersed by rain drops.
Where are gemma cups found?
Do mosses have gemmae?
In mosses and liverworts The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as Marchantia, the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface.
What are gemmae write their function?
Gemmae means of asexual propagation in plants. These structures are commonly found in fungi, algae, liverworts and mosses. A gemma (plural gemmae) is a single cell that detaches from the parent and develops into a new individual.
Where are gemma cups located?
These cups are located at the apex of the leafy moss and function in reproduction. The moss makes little discs of plant tissue inside the cups called gemmae. These gemmae are moved away from the parental plant via a splash-cup dispersal mechanism.
What is gemma name the plant that has gemma?
The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as Marchantia, the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface. The gemma cups are cup-like structures containing gemmae.
What is Marchantia gemma Cup?
Summary. The basal land plant Marchantia polymorpha efficiently propagates in favourable environments through clonal progeny called gemmae. Gemmae develop in cup-shaped receptacles known as gemma cups, which are formed on the gametophyte body.

What are gemmae and gemma cups?
The gemma cups are cup-like structures containing gemmae. The gemmae are small discs of haploid tissue, and they directly give rise to new gametophytes. They are dispersed from gemma cups by rainfall. The gemmae are bilaterally symmetrical and are not differentiated into dorsal and ventral surfaces.
