Question

Which of the following generation is dominant in vascular plants?

• A. Gametophytic generation
• B. Diploid sporophytic generation
• C. Haploid sporophytic generation
• D. None of the above

Answer 1

The correct option is B Diploid sporophytic generation

• A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid sperm cell is fertilized a haploid egg, and each sporophyte cell, therefore, has a double set of chromosomes, one set from each parent.
• All vascular plant, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase.

So the correct answer is option B.
