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 multicellular sporophyte |

  1. A
    (a)-(iv); (b)-(i); (c)-(ii); (d)-(iii)
  2. B
    (a)-(ii); (b)-(iii); (c)-(iv); (d)-(i)

  4. D
    (a)-(ii); (b)-(iv); (c)-(i); (d)-(iii)

Solution & Step-by-step Explanation

1. Spirogyra (Alga): Haplontic life cycle with dominant free-living gametophyte (ii).2. Fern (Pteridophyte): Haplo-diplontic with dominant sporophyte and heart-shaped prothallus (iii).3. Funaria (Bryophyte): Haplo-diplontic with dominant gametophyte and partially dependent sporophyte (iv).4. Cycas (Gymnosperm): Diplontic with dominant sporophyte and highly reduced gametophyte (i).Sequence: (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
