Question

The diploid sporophyte is represented by a dominant, independent, photosynthetic, vascular plant body. It alternates with multicellular, saprophytic/autotrophic, independent but short-lived haploid gametophyte. This type of pattern is exhibited by

• A. Pteridophytes $\left(\text{Selaginella and Lycopodium}\right)$
• B. Bryophytes $\left(\text{Sphagnum and Polytrichum}\right)$
• C. Seed plants $\left(\text{Gymnosperms and Angiosperms}\right)$
• D. Most of the algal genera $\left(\text{Fucus, Chara and Polysiphonia}\right)$

Answer 1

The correct option is A

Pteridophytes $\left(\text{Selaginella and Lycopodium}\right)$

Pteridophytes (Selaginella and Lycopodium)

Plants like Pteridophytes exhibit a haplo-diplontic life-cycle in which both gametophytic and sporophytic phases are multicellular. In Pteridophytes the diploid sporophytes are vascular, photosynthetic, free living and dominant whereas the haploid gametophytes are also independent $\left(\text{with autotrophic or saprophytic nutrition}\right)$ but short lived.

Final answer

$b.$ Pteridophytes $\left(\text{Selaginella and Lycopodium}\right)$
