Match the plant with the kind of life cycle it exhibits: Choose the correct answer from the options given below :
- (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
- (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
- (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
- (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
Answer
(2) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
Solution
(a) Spirogyra (alga) shows a haplontic life cycle: the dominant phase is the haploid free-living gametophyte ⇒ (ii).
(b) Fern (pteridophyte): dominant diploid sporophyte alternating with a reduced, independent gametophyte called prothallus ⇒ (iii).
(c) Funaria (moss, bryophyte): dominant haploid leafy gametophyte alternating with a partially dependent multicellular sporophyte ⇒ (iv).
(d) Cycas (gymnosperm): dominant diploid sporophyte vascular plant with highly reduced male or female gametophyte ⇒ (i).
∴ (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
Answer: (2)
