  3. Cproduces gametes that give rise to the gametophyte
  4. Darises from a spore produced from the gametophyte

Correct answer

B. is partially parasitic on the gametophyte

Step-by-step solution

In mosses, the sporophyte developing from the embryo partially depends on the gametophyte. It contains chlorophyll and hence is capable of making its own food. Sporophyte is attached to the photosynthetic gametophyte so that it can get nourishment from the gametophyte. Some cells of the sporophyte undergo meiosis to produce haploid spores. The spores germinate to produce gametophyte. Related Theory When a moss spore germinates it first develops a protonema (sporophyte), a filamentous to sheet-like growth form. the
