Moss life cycle diagram illustrating the alternation of generations between haploid and diploid stages.

Final Answer:
1. Angiosperms
2. Mosses
3. Pteridophytes
4. Gnetophytes (or sometimes Cycadophyta, depending on chart)
5. a. Non-vascular or simple vascular tissue
b. Reproduce via spores
c. Need water for fertilization
d. Alternation of generations life cycle
6. a. Mosses are non-vascular; ferns have vascular tissue
b. Mosses have dominant gametophyte stage; ferns have dominant sporophyte stage
7. (Labels to place on diagram):
- Spores (n) → Haploid stage
- Gametophyte → Haploid stage
- Egg (n) and Sperm (n) → from gametophyte
- Fertilization → forms Zygote (2n)
- Zygote (2n) → grows into Sporophyte (2n)
- Meiosis in capsule → produces Spores (n) again
8. (Observations vary by sample — student should describe texture, color, size, etc.)
