The development of young embryos of pteridophytes within the female gametophytes is a precursor to the
1 Fruit habit
2 Embryo habit
3 Seed habit
4 Flower habit
Explanation:
The development of the zygotes into young embryos take place within the female gametophytes. This event is a precursor to the seed habit considered an important step in evolution.

Which of the following is true about prothallus?
1 A gametophytic free living structure formed in bryophytes
2 A gametophytic free living structure formed in pteridophytes
3 A structure in bryophytes formed before the thallus develops
4 A primitive structure formed after fertilization in pteridophytes.
Explanation:
The spores in pteridophytes germinate to give rise to inconspicuous, small but multicellular, free-living, mostly photosynthetic thalloid gametophytes called prothallus.
