Question

Match the columns I and II and choose the correct combination from the options given: Column I Column II

a. Haplontic life cycle	i. Gymnosperms and angiosperms
b. Diplontic life cycle	ii. Spirogyra
c. Haplo-diplontic life cycle	iii. Bryophytes and pteridophytes

• A. a-i, b-ii, c-iii
• B. a-iii, b-i, c-ii
• C. a-ii, b-i, c-iii
• D. a-ii, b-iii, c-i

Answer 1

The correct option is C a-ii, b-i, c-iii

Spirogyra shows haplontic life cycle, where the haploid phase is more predominant than the diploid phase in the life cycle.

Gymnosperms and angiosperms show a diplontic life cycle where the diploid phase is more predominant in the life cycle.

Bryophytes and pteridophytes show haplo-diplontic lifecycle where both the haploid and the diploid phases are equally prevalent in their life cyles.
