Answer: 4. Some Liverworts

Gemmae are small green multicellular buds that form in gemma cups on the thallus. They are a means of asexual reproduction in some liverworts such as Marchantia.

Mosses mainly multiply vegetatively by fragmentation and by buds on the secondary protonema. Pteridophytes and gymnosperms do not form gemmae.
