Solution

The correct option is C Gemmae are the reproductive structures
Asexual reproduction in bryophytes takes place by gemmae. Gemmae are bud-like mass of undifferentiated tissue which helps in asexual (vegetative) reproduction among mosses and liverworts. Bryophytes are called the 'amphibians of the plant kingdom' because they can live in land but dependent on water for sexual reproduction. Bryophytes comprise of mosses and liverworts. The plant body is thallus like and lacks true roots, stem, or leaves. It bears gametes; hence it is called a gametophyte. In mosses, after fertilization, the zygote grows into a sporophyte consisting of the foot, seta, and capsule.
