Question

Match the plant with the kind of life cycle it exhibits. Choose the correct answer from the options given below:

| 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

(a)- (ii); (b) - (iii); (c) - (iv);(d) - (i)

Answer 2

Spirogyra: Sporophytic generation is represented only by the one-celled zygote. There are no free-living sporophytes. The dominant, photosynthetic phase in such plants is the free-living gametophyte.
Fern: The diploid sporophyte is represented by a dominant, independent, photosynthetic, vascular plant body. It alternates with multicellular, saprophytic/autotrophic, independent but short-lived haploid gametophyte.
Funaria: Dominant haploid leafy gametophyte alternating with partially dependent multicellular sporophyte.
Cycas: Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte. This is found in all gymnosperms (Cycas) and angiosperms.
