Explanation
Gemmae are vegetative reproductive structures found in B: Bryophytes.
Bryophytes, such as mosses, liverworts, and hornworts, are non-vascular plants that reproduce through a variety of means, including sexual reproduction and asexual reproduction. One type of asexual reproduction in bryophytes involves the production of gemmae, which are small, multicellular structures that detach from the parent plant and grow into new individuals.
Gemmae are typically produced in specialized structures called gemma cups, which are small cups or structures on the surface of the gametophyte. When the cups are filled with water, the gemmae are released and can grow into new gametophytes.
Gemmae are an adaptation to the moist habitats in which bryophytes typically grow. By producing small, compact vegetative propagules, bryophytes can disperse and establish new populations more easily in these environments.
