Gemmae are asexual reproductive structures found in certain plants, particularly bryophytes like liverworts. Their primary function is to facilitate vegetative reproduction, allowing the plant to produce new individuals without the need for seeds or spores. When conditions are favorable, gemmae can be dispersed by water or wind, ultimately growing into new plants that are genetically identical to the parent. This adaptation helps ensure species survival in varying environmental conditions.
Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.

A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
A gemmae cup is a cup-shaped structure found in liverworts that contains gemmae, which are small, asexual reproductive structures. Gemmae cups are usually located on the upper surface of the thallus (body) of the liverwort plant. They are specialized for dispersing gemmae, which can give rise to new plants under suitable conditions.
Gemmae cups in Marchantia sp. are crucial for asexual reproduction. These specialized structures contain gemmae, which are small, haploid fragments that can develop into new gametophyte plants. When water splashes onto the gemmae cups, the gemmae are dispersed, allowing for colonization of new areas. This reproductive strategy enhances the survival and spread of Marchantia in various environments.

Gemmae
They are one- to several-celled or sometimes multicellular propagules called gemmae that are produced on the margins and surfaces or at the tips.
A small cellular body or bud that can separate to form a new organism.
Gemmae are small, asexual reproductive structures produced by certain non-flowering plants, such as liverworts and some mosses. They are typically formed in specialized cups or structures on the parent plant and can be released when water splashes or through wind. Once detached, gemmae can be dispersed to new locations, where they can germinate and grow into new individual plants, thereby allowing for effective colonization of their environment.
Seedless nonvascular plants, such as mosses and liverworts, can reproduce asexually through fragmentation and gemmae production. In fragmentation, pieces of the plant can break off and develop into new individuals. Gemmae are small, multicellular structures produced in specialized structures called gemmae cups; when dispersed, they can grow into new plants. Both methods allow these plants to spread and colonize new areas efficiently.
Liverworts can also reproduce asexually by means of special structures called gemmae cups. These little cups can be easily seen on the surface of the plant. Each gemma cup contains a number of tiny plantlets called gemmae, and a single drop of water will disperse them. These little vegetative "clones" will then grow into a new gametophyte.
The small bits of tissue that are carried in cup-like structures on liverworts, are called villi.
gemmae
Liverworts are non-vascular plants that lack true stems and leaves. They reproduce via spores or asexual, through gemmae cups. Liverworts grow close to the ground and are commonly found in moist environments.
