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.
