Gemmae Cups and Gemmae in Marchantia Thallus
Gemmae Cups:
- Gemma cups are the structures in which gemmae are produced.
- These are found on the dorsal surface of the thallus of Marchantia, a liverwort plant.
- The cups are small and cup-shaped, about 2-3 mm in diameter.
- They are surrounded by a few specialized leaves called perianth, which protect the gemmae from desiccation and other environmental stresses.
Gemmae:
- Gemmae are small, multicellular green structures that are produced asexually for vegetative propagation.
- They are about 0.3-0.5 mm in diameter and contain a small number of cells.
- Each gemma is capable of producing a new plant when it lands on a suitable substrate and germinates.
Vegetative Propagation:
- Vegetative propagation is the process of producing new plants from vegetative parts of a parent plant, such as roots, stems, and leaves.
- Gemmae are one of the methods of vegetative propagation used by liverworts and some other plants.
Marchantia Thallus:
- Marchantia is a genus of liverwort plants that are commonly found in damp, shady habitats worldwide.
- The thallus of Marchantia is the plant body that lacks true roots, stems, and leaves.
- It is a flat, lobed structure that grows on the ground or on other substrates such as rocks, soil, or tree trunks.
- The thallus is capable of photosynthesis and reproduction, and contains specialized structures such as gemma cups, antheridia, and archegonia.

In Marchantia, the plant body consists of a dorsrventrally flattened, prostrate and dichotomously branched thallus. The thalli are conspicuous, apex of each thallus is notched. Along the midriba represent characteristic, prominent goblet or cup-shaped structures, the gemma cups, with smooth, dentate or frilled margins. These cups enclose asexual reproductive bodies called gemma.
