Answer:
A
Solution:
| List-I | List-II | ||
| (a) | Spirogyra | (ii) | It is a filamentous green alga, member of Thallophyta. The predominant phase is haploid free-living gametophyte. They show haplontic life cycle. |
| (b) | Fern | (iii) | They are Pteridophyta members. The predominant plant body is diploid sporophyte alternating with reduced gametophyte called prothallus.They show diplo-haplontic life cycle. |
| (c) | Funaria | (iv) | They are Bryophyta members. The gameotyphyte is dominant haploid, and leafy. They have alternating partially parasitic mutlicellular, diploid sporophyte generations in their life cycle. They show haplo-diplontic life cycle. |
| (d) | Cycas | (i) | All Gymnosperms are dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte. They have highly reduced gametophytic, haploid generation and diplontic life cycle. |
