The upcoming discussion will update you about the difference between Marchantiophyta, Anthocerotophyta and Bryophyta.
Difference # Marchantiophyta:
1. Thallus or leafy shoot; thallus simple or with air chambers.
2. In leafy shoot, leaves arranged in three rows, one ventral and two lateral.
3. Leaves divided into two or more lobes, and without midvein.
4. Rhizoids in marchantiophyta are hyaline, one-celled, unbranched.
5. Water conducting cells are present only in a few simple thalloid gametophytes in marchantiophyta.
6. Special organelles of marchantiophyta is oil bodies.
7. On upper surface of thallus or as apical clusters in leafy forms.
8. Stomata in marchantiophyta is absent in both generations.
9. Delicate and short-lived, lasting several hours to a few days.
10. Very delicate, translucent to transparent, elongating just prior to spore release.
11. Undifferentiated, globose or ellipsoid of fixed size.
12. Sterile cells in capsule of marchantiophyta are spirally thickened elaters.
13. Capsule dehiscence is divided into four valves in marchantiophyta.
14. The spores are dispersed into the winds by the twisting motions of numerous elaters and the entire spore mass of a single capsule is discharged in just a few minutes.
15. Globose and forms a single bud (shoot).
Difference # Anthocerotophyta:
1. Simple, flat, lobed and unspecialised thallus.
2. Leaf arrangement in anthocerotophyta is not applicable.
3. Leaf form in anthocerotophyta is not applicable.
4. Hyaline, one-celled, un- branched.
5. Water conducting cells are absent in anthocerotophyta.
6. Special organelles of anthocerotophyta are chloroplasts with pyrenoids.
7. Sunken in thallus, scattered.
8. Present in both sporophyte and gametophyte.
9. Very strong and long- lived, lasting for several weeks.
10. Seta is absent in anthocerotophyta.
11. Undifferentiated, horn-shaped, growing continuously from a basal meristem.
12. Columella and pseudo- elaters.
13. Capsule dehiscence is divided into two valves in anthocerotophyta.
14. The spores are mostly dispersed by water movement rather than by wind which is taking place gradually over a long period of time.
15. Globose and forms a single bud (shoot).
Difference # Bryophyta:
1. Gametophyte form of bryophyta is Leafy shoot.
2. Leaves arranged spirally on upright branched axis.
3. Leaves undivided, with a distinct midvein.
4. Reddish-brown, multicellular, branched.
5. Present in both gametophytes and sporophytes.
6. Bryophyta has no special organelles.
7. Gametangial position is as apical clusters in bryophyta.
8. Stomata in bryophyta is only present in sporophyte capsule.
9. Sporophyte in bryophyta are strong and long-lived, lasting for several weeks.
10. Seta in bryophyta are strong, green, photosynthetic, emergent from gametophyte early in development.
11. Complex with operculum, theca and neck, of fixed size.
12. Sterile cells in capsule of bryophyta is columella.
13. Capsule dehiscence is at operculum and peristome teeth in bryophyta.
14. The spores are released into the drying wind by the help of peristome teeth which is taking place in a few minutes.
15. Filamentous, differentiated into caulonemal filament and chloronemal filament, numerous buds (shoots) develop from each protonema.
