Labeled Structures

1. Gametophyte (Parent Plant) — The green leafy moss that nourishes the sporophyte
2. Foot — Embedded structure absorbing water and nutrients from the gametophyte
3. Seta (Stalk) — Slender stalk elevating the capsule for wind dispersal
4. Spore Capsule (Sporangium) — Where meiosis produces haploid spores
5. Calyptra — Protective hood from archegonium tissue, falls away at maturity
6. Operculum (Lid) — Circular lid sealing the capsule until spores are ready
7. Peristome Teeth — Humidity-sensitive teeth controlling spore release
8. Spores — Haploid single-celled reproductive units dispersed by wind
