Question

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

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
(b) Cycas	(iv) Dominant haploid leafy gametophyte alternating with partiaIly dependent multicellular sporophyte

Choose the correct answer from the options given below:

• A. (a)- (iv),(b)-(i), (c)-(ii), (d)- (iii)
• B. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
• C. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
• D. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Answer 1

The correct option is D (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Spirogyra is a green alage, haplontic life cycle.

Fern is a pteridophyte – Life cycle shows dominant diploid sporophyte, alternating with reduced free living gametophytic stage. So its Haplo-diplontic life cycle

Funaria – belongs to Bryophyta. Its a moss plant. Exhibits haplo diplontic lifecycle. The free living haploid gametophyte bears the sporophytic plant body.

Cycas – Gymnosperms.
Gymnosperms exhibit dominant diploid saprophytic plant body, with highly reduced male/female gametophyte.

So, the corerct answer is "option D"
