Let me share with you a difference between bryopsida and anthoceropsida.
| Aspect | Bryopsida | Anthoceropsida |
| Common name | Mosses | Hornworts |
| Gametophyte Structure | Leafy, with stems and leaves | Thalloid, lacks well-differentiated stems and leaves |
| Sporophyte | Elevated seta (stalk) with capsule at the tip | Simple sporophyte embedded in the thallus |
| Capsule Dehiscence | Often dehisce through a peristome, a specialized structure | Split longitudinally, releasing spores |
| Rhizoids | Single-celled, often clustered on the lower surface | Single-celled, often scattered on the lower surface |
| Stomata | Absent | Absent |
| Chloroplast | Single cup-shaped chloroplasts | Single plate-like chloroplasts |
| Role in nitrogen fixation ability | Some mosses can associate with nitrogen-fixing cyanobacteria | Some hornworts can fix nitrogen through symbiosis with cyanobacteria |
| Gemmae Cup Presence | Some mosses have gemmae cups for asexual reproduction | Lacks gemmae cups for asexual reproduction |
| Habitat | Diverse habitats, including moist woodlands, rocks and soil | Moist environments, often associated with soils and rocks |
