| 21. | All three bryophyte groups share a haploid-dominant life cycle and unbranched sporophytes.
|
| 22. | The horn-shaped sporophyte grows from an archegonium embedded deep in the gametophyte.
|
| 23. | The condition of having separate sporophyte and gametophyte plants is call alternation of generations.
|
| 24. | Ensuing evolution caused the sporophyte to become increasingly complex, both organographically and anatomically.
|
| 25. | The spores of a sporophyte produce either tetrasporophytes.
|
| 26. | In the mosses and hornworts a cuticle is usually only produced on the sporophyte.
|
| 27. | Multiple sporophytes are often present in one plant.
|
| 28. | The sporophyte is likened to an elongated spindle.
|
| 29. | The fertilised zygotes germinate into young sporophytes which will grow into the mature seaweed.
|
| 30. | The sporophyte has a chromosome number of 108.
