Question

Match the plant with the kind of life cycle it exhibits:

List-I
(a) Spirogyra
(b) Fern
(c) Funaria
(d) Cycas

List-II
(i) Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte
(ii) Dominant haploid free-living gametophyte
(iii) Dominant diploid sporophyte alternating with reduced gametophyte called prothallus
(iv) Dominant haploid leafy gametophyte alternating with partially dependent multicellular sporophyte

Accepted Answer

1. Spirogyra is an alga. Algae typically exhibit a haplontic life cycle where the dominant, photosynthetic phase is the free-living haploid gametophyte .
2. Fern is a pteridophyte. Pteridophytes exhibit a haplo-diplontic life cycle where the dominant phase is the diploid sporophyte, which alternates with a small, multicellular, free-living gametophyte called a prothallus .
3. Funaria is a moss (bryophyte). The predominant stage is the haploid gametophyte (with a leafy stage), and the sporophyte is partially dependent on it .
4. Cycas is a gymnosperm. Gymnosperms are vascular plants with a dominant diploid sporophyte and highly reduced gametophytes .
