| Column I | Column 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 |
| (d) Cycas | (iv) Dominant haploid leafy gametophyte alternating with partially dependent multicellular sporophyte |
To solve this problem, we need to match each plant with the type of life cycle it exhibits. Let's analyze each plant:(a) Spirogyra: - Spirogyra is a type of green algae that exhibits a haplontic life cycle. - In this cycle, the dominant phase is the haploid gametophyte, which is free-living. - This matches with (ii) Dominant haploid free-living gametophyte.(b) Fern:
