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.
- A
(a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
- B
(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
- C
(a)-(iii), (b)-(iv), (c)-(i), (d)-(i)
- D
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
Match each plant to its dominant phase and life-cycle pattern.
Spirogyra, a green alga, has a haplontic life cycle in which the dominant free-living phase is the haploid gametophyte, so (a) maps to (ii).
Ferns (pteridophytes) have a diplontic-dominant life cycle: the sporophyte is large and dominant, while the gametophyte is a small reduced prothallus, so (b) maps to (iii).
Funaria, a moss, has a haplodiplontic life cycle with a dominant haploid leafy gametophyte and a partially dependent multicellular sporophyte, so (c) maps to (iv).
Cycas, a gymnosperm, has a dominant diploid sporophyte (vascular plant) with highly reduced male and female gametophytes that develop within the parent plant, so (d) maps to (i).
