Read the following description of a reproductive structure found in certain bryophytes: "They are green, multicellular, asexual buds which develop in small receptacles located on the thalli. They become detached from the parent body and germinate to form new individuals." Identify the structure described above.

Step-by-step solution

According to NCERT, asexual reproduction in liverworts takes place by fragmentation of thalli, or by the formation of specialised structures called gemmae. Gemmae are green, multicellular, asexual buds, which develop in small receptacles called gemma cups located on the thalli. The gemmae become detached from the parent body and germinate to form new individuals. Protonema is the juvenile stage in mosses. Bulbils are vegetative propagules in some angiosperms like Agave. Sporangia are spore-producing structures of t
