Answer and explanation:

a) Spore - N:  The adult diploid vegetable (2n) produces spores (n) by meiosis, which is why we call it sporophyte (spore producer).

b) Calyptra - 2N: Calyptra is an enlarged archegonian belly that protects the capsule containing the embryonic sporophyte. Calyptra are normally lost before the spores are released from the capsule.

c) Egg - N: Eggs are structures present in the ovary of plants, that implies that they are part of the gametophyte.

d) Protonema - 2N: The protonema is a cell body that gives rise to the gametophyte, in other words, the protonema is a young gametophyte, and like the gametophyte, it has 2N ploidy

e)  Arquegonium - 2N: Female sexual organ (gametangium), bottle-shaped, characteristic of bryophytes, pteridophytes and most gymnosperms, as part of the reproductive structure, its ploidy is 2N

f)  Paraphysis - N: Sterile hyphae of the fruiting body (fertile spore-bearing layer) of several ascomycete fungi. They are part of the gametophyte (surrounding the antheridia and archegonium).

g) Zygote - N:  From the fertilization of the gametes, the diploid zygote (2n) is formed, which will develop forming the adult individual. Meiosis in this cycle is known as final or gametic meiosis.

h) Capsule - 2N: It is in the capsule that the transition from the mother cell (2N) to the spore cell (N) occurs. The capsule is protected by calyptra (2N)

i) Seta - 2N: Setae are primarily part of the sporophyte, but can appear in some specific gametophyte phases (in parasitism). They support the capsule and assist in nutrient uptake.
