Q. Match the plant with the kind of life cycle it exhibits: [table] 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 [/table] Choose the correct answer from the options given below.
A) A-ii B-iv C-i D-iii
B) A-iv B-i C-ii D-iii
C) A-ii B-iii C-iv D-i
D) A-iii B-iv C-i D-ii
Explanation
[Solution] $Spirogyra$ is haplontic (free-living gametophyte); fern has a dominant sporophyte with a prothallus; $Funaria$ has a leafy gametophyte with a dependent sporophyte; $Cycas$ has a dominant sporophyte with highly reduced gametophytes. Answer (3).
