Answer #1

1.A is correct.Meiosis results in formation of gametes.

Spores are not reproductive cells.

Gametophytes are haploid but multicellular.

Plant Sporophytes(2n) do not grow from haploid spores directly.It devolops from gametes produced by gametophyte and gametophyte(n) are formed from spores.

2.C is the answer.Pteridophytes produce flagellated sperms.

3.C is the answer.Charophytes are close relatives of terrestrial plants.Their chloroplast genome is similar to terrestrial plants.
