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 (iii) Bryophytes and Pteridophytes
Options
- Aa — i , b —iii , c — i i
- Ba — i i i , b — i , c — i i
- Ca — i i , b — i , c — i i i
- Da — i i b — i i i , c — i
Correct answer
C. a — i i , b — i , c — i i i
Step-by-step solution
The main form of the haplontic life cycle is haploid and diploid zygote is formed in this cycle for a short period of time and this type of life cycle is found in Spirogyra . The main form of a diplontic life cycle is diploid which produces gametes and this type of life cycle is found in Gymnosperm and Angiosperm. In haplo-diplontic life cycle, multicellular diploid sporophyte is present which produces haploid spores via meiosis and it is found in Bryophyta and Pteridophyta.
