Question

Select the incorrect statement with respect to given type of life cycle.

• A. Meiosis occurs at the time of spore formation in sporophytic plant.
• B. Gametophytic plant is produced by germination of spores.
• C. This life cycle is exhibited by most algae and seed bearing plants.
• D. This life cycle is exhibited by many bryophytes and pteridophytes.

Answer 1

Answer: (C)

This life cycle is exhibited by most algae and seed bearing plants.

Given type of life cycle is haplodiplontic or diplohaplontic life cycle in which haploid gametophytic phase and diploid sporophytic phase alternate with each other. The gametophytic plant (n) produces gametes (n), which fuse to give rise to the diploid zygote (2n). Zygote grows to form sporophytic plant body (2n). Meiosis occurs in the sporophyte at the time of formation of spores and the spores germinate to produce gametophytic plants. Bryophytes and pteridophytes exhibit this life cycle pattern. Algae exhibit haplontic life cycle pattern and gymnosperms and angiosperms follow diplontic life cycle pattern.

So the correct option is C.
