Male gametophyte with least number of cells is present in
1 Pteris
2 Funaria
3 Lilium
4 Pinus
Explanation:
Lilium, an angiosperm bears the least called male gametophyte as compared to Funaria (bryophyte). As we progress from algae to angiosperms, gametophytes get reduced.

Which of the following statements is correct?
1 Horsetails are gymnosperms
2 Selaginella is heterosporous, while Salvinia is homosporous
3 Ovules are not enclosed by ovary wall in gymnosperms
4 Stems are usually unbranched in both Cycas and Cedrus
Explanation:
Gymnosperms are naked seeded plants because the ovule is not enclosed by ovarian wall. Horsetails are Pteridophytes. Both Selaginella and Salvinia are heterosporous. Stem in Cycas is unbranched and Stem in Cedrus is branched.
