Calyptra in mosses protect the growing tip of the sporophyte and help with spore dispersal. They act as a protective cover for the developing sporangium before it is ready to release spores, and also aid in the controlled release of spores for reproduction.

What is the ploidy level of seta calyptracapsule operculum and perstome of moss plant?

In mosses, the seta, calyptra, capsule, operculum, and peristome are all part of the sporophyte generation, which is diploid (2n). The seta is the stalk that supports the capsule, while the calyptra is the protective cap that covers the developing capsule. The operculum is the lid of the capsule, and the peristome consists of structures that aid in spore dispersal. Overall, all these structures are diploid, arising from the fusion of gametes in the haploid gametophyte stage.
