Top-shaped multiciliate male gametes and the mature seed which bears only one embryo with two cotyledons, are characterised features of

  1. cycads
  2. conifers
  3. polypetalous angiosperms
  4. gamopetalous angiosperms

Answer

(1) cycads

Solution

Cycads (e.g. Cycas) have the largest male gametes in the plant kingdom; they are top-shaped and bear a spiral band of numerous cilia (multiciliate), so they are motile.

⇒ Conifers have non-motile male gametes, and angiosperms have non-motile male gametes carried by pollen tubes.

⇒ Although a cycad ovule may contain several archegonia (polyembryony), the mature seed bears only one embryo with two cotyledons.

∴ These features characterise cycads.
