Gametophyte is a dominant phase in the life cycle of a bryophyte. It is more conspicuous, long living, independent, green and freely branched whereas, the sporophytic phase is short lived and dependent upon the gametophyte. The main plant body is haploid and bears sex organs i.e., antheridium and archegonium. Antheridium produces a large number of flagellated male gametes called antherozoids and archegonium is flask shaped with tubular neck and swollen venter. The gametophytic plant body of bryophytes is thalloid in liverworts whereas foliose in mosses. In liverworts, the thallus is differentiated into a dorsal photosynthetic and ventral storage region. In mosses, the gametophyte has two growth stages- protonema stage and leafy stage or gametophore.
Q. In a moss, sporophyte
- a)Manufactures food for itself as well as for gametophyte.
- b)Is partially parasitic on gametophyte.
- c)Produce gametes that give rise to gametophyte.
- d)Arises from a spore produced from the gametophyte.
Correct answer is option 'B'. Can you explain this answer?

Moss sporophyte remain attached on gametophyte and absorb nutrient from it. It becomes green in some region and thus becomes photosynthetic and prepares it own food, thus it is partially parasitic on gametophyte.

Explanation:
Sporophyte in a moss is partially parasitic on gametophyte because:
- The sporophyte in a moss is a dependent structure that remains attached to the gametophyte for its entire life.
- It obtains nutrients and water from the gametophyte through a structure called the foot.
- The sporophyte of a moss is relatively short-lived compared to the gametophyte, which is the dominant and long-living phase of the moss life cycle.
- The sporophyte produces spores through meiosis, which are released into the environment. These spores germinate into a protonema, which eventually develops into a new gametophyte.
Therefore, the sporophyte in a moss is considered partially parasitic on the gametophyte because it relies on the gametophyte for its nutrition and support.
