| 11. | Fertilized eggs become zygotes, which develop into sporophyte embryos inside the archegonia.
|
| 12. | In seed plants, " dioecious " where they occur on different sporophytes.
|
| 13. | Further divisions produce three basic regions of the sporophyte.
|
| 14. | Sporophytes are fairly tolerant of drought, but require well-drained soils.
|
| 15. | Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores.
|
| 16. | The sporophyte is erect when mature, growing up to 5 cm tall.
|
| 17. | What was the evolutionary incentive for initiating separate-sex " sporophytes "?
|
| 18. | Most members of Lycopodiophyta bear a protostele, and the sporophyte generation is dominant.
|
| 19. | After fertilisation, the immature sporophyte pushes its way out of the archegonial venter.
|
| 20. | It takes about a quarter to half a year for the sporophyte to mature.
