Question: 126: 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 |
Choose the correct answer from the options given below :
(1) (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
(2) (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
(3) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
(4) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
Answer: Option (4)
Explanation:
Spirogyra is a green alga that shows a haplontic life cycle, where the haploid gametophyte is dominant and free-living, so (a) matches with (ii).
Fern is a pteridophyte in which the diploid sporophyte is dominant and alternates with a small,
independent gametophyte called prothallus, so (b) matches with (iii).
Funaria is a bryophyte that shows a dominant haploid leafy gametophyte,
while the sporophyte is multicellular but partially dependent on the gametophyte,
so (c) matches with (iv).
Cycas is a gymnosperm in which the diploid sporophyte is dominant and the male and female
gametophytes are highly reduced and dependent, so (d) matches with (i).
Thus, the correct matching corresponds to Option (4).
