The protonema is the first stage of the moss gametophyte, which develops directly from a germinating spore. It is characteristically green, filamentous, and branched.

The archegonium of Funaria typically possesses a long neck containing a series of neck canal cells, usually numbering between 6 and 10.

The fusion of male and female gametes results in a zygote. While terms like oospore are sometimes used in specific botanical contexts, zygote is the standard biological term for the product of fertilization.

Bryophyte sperms (antherozoids) are biflagellate and typically curved or spirally coiled. Option B is the standard description for Funaria.

In bryophytes, the sporophyte is physically attached to and nutritionally dependent on the gametophyte throughout its life.

The rhizoids of Funaria are multicellular, branched, and possess oblique septa, which is a key diagnostic feature distinguishing them from other bryophyte rhizoids.

Funaria is a bryophyte and lacks true roots (it has rhizoids), whereas Selaginella is a pteridophyte and possesses true roots.

Meiosis in Funaria occurs within the capsule inside the spore mother cells to produce haploid spores.

The peristome in Funaria consists of two rings of 16 teeth each, totaling 32 teeth.

Funaria is monoecious (both sex organs on the same plant) and autoicous (sex organs on different branches of the same plant).
