Match the plant with the kind of life cycle it exhibits:

  List-I   List-II
(a) Spirogyra (i) Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte
(b) Fern (ii) Dominant haploid free-living gametophyte
(c) Funaria (iii) Dominant diploid sporophyte alternating with reduced gametophyte called prothallus
(d) Cycas (iv) Dominant haploid leafy gametophyte alternating with partially dependent mutlicellular sporophyte

Choose the correct answer from the options given below:

  1. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
  2. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
  3. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
  4. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Solution

  List-I   List-II
(a) Spirogyra (ii)

It is a filamentous green alga, member of Thallophyta. The predominant phase is haploid free-living gametophyte. They show haplontic life cycle.
(b) Fern (iii) They are Pteridophyta members. The predominant plant body is diploid sporophyte alternating with reduced gametophyte called prothallus.They show diplo-haplontic life cycle.
(c) Funaria (iv) They are Bryophyta members. The gameotyphyte is dominant haploid, and leafy. They have alternating partially parasitic mutlicellular, diploid sporophyte generations in their life cycle. They show haplo-diplontic life cycle.
(d) Cycas (i) All Gymnosperms are dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte. They have highly reduced gametophytic, haploid generation and diplontic life cycle.
