Cycas and Adiantum resemble each other in having

  1. seeds
  2. motile sperms
  3. cambium
  4. vessels

Answer

(2) motile sperms

Solution

Adiantum is a fern (pteridophyte) and Cycas is a gymnosperm.

∵ Adiantum has no seeds and no cambium, and neither plant has vessels in its xylem ⇒ (1), (3), (4) are ruled out.

∵ Both have multiflagellate motile male gametes (sperms) ⇒ they resemble each other in having motile sperms.

Answer: (2)

Selaginella and Salvinia are considered to represent a significant step toward evolution of seed habit because

  1. female gametophyte is free and gets dispersed like seeds.
  2. female gametophyte lacks archegonia.
  3. megaspores possess endosperm and embryo surrounded by seed coat.
  4. embryo develops in female gametophyte which is retained on parent sporophyte.
