The structure of the plant body of a pteridophyte
1 Is the most well-developed in plant kingdom
2 Posses true root, leaves and stem
3 Is thalloid
4 Possess rhizoids
Explanation:
Pteridophytes are the first plants to bear true roots, steam and leaves.

Heterosporous pteridophytes are
1 Selaginella and Salvia
2 Selaginella and Lycopodium
3 Selaginella and Salvinia
4 Adiantum and Psilotum
Explanation:
Genera Selaginella and Salvinia are heterosporous pteridophytes.

Fern plant in its dominant phase is a
1 haploid gametophyte
2 diploid gametophyte
3 diploid sporophyte
4 haploid sporophyte
Explanation:
Fusion of male gamete with the egg results in the formation of zygote. This zygote produces a multicellular well differentiated sporophyte which is the dominant phase of the pteridophytes.
