Actually Pteridophytes are ferns and the like. They have spores. I think Gymnosperms is the term you're thinking of. It comes from the Greek for naked seed.
The spore bearing structures in club mosses and horsetails and the cones of gymnosperms called strobili.
It starts with a seed or spores and slowly turns into maturity. It germinates later. Angiosperms are flowering seeds, so it is covered by a fruit such as apples. Gymnosperms are unprotected seeds,so there are less possibilities to reproduce than angiosperms. Gymnosperms are usually all spores and there are more gymnosperms than angiosperms because of the possibility of growing.
Too many to name. A sporagium is just a stalk supported sac that contains spores. Angiosperms and gymnosperms have these also.
Plants belonging to bryophytes and Pteridophytes etc. reproduce with spores and thoseof gymnosperms and angiosperms reproduce with seeds.
No, the majority produce by spores, only the gymnosperms produce by (naked) seed
in cones
