Question

The Sporophyte is the dominant phase in

• A. Pteridophytes
• B. Gymnosperms
• C. Angiosperms
• D. All of these

Answer 1

The correct option is D All of these

The plant body or the vegetative phase is diploid in pteridophytes, gymnosperms and angiosperms. The reproductive structures like the stobili in pteridophytes, ovules and microsporangium, anther are also diploid. Here, only the reproductive cells undergo meiosis or gametogenesis to give rise to male and female gametes that are haploid. These fuse to produce a diploid zygote. So, the gametophytic stage is restricted and of a very short duration as compared to the sporophytic stage. therefore, sporophyte is a dominant phase.

So, the correct answer is 'All of these'
