Question

Which of the following statements is correct about the gametophytic stage in the alternation of generation within the life cycle of a plant?

• A. It is the generation that produces the gametes
• B. It is the generation that produces the spores
• C. It is the generation that produces vascular tissue
• D. It is the diploid generation of a plant

Answer 1

The correct option is A It is the generation that produces the gametes

Plants exhibit two phases in their life cycle:
i) Gametophytic: Gamete bearing, haploid stage is predominant
ii) Sporophytic: Spore bearing, diploid stage is predominant

Gametophyte is the phase which has haploid number of chromosomes and produces
gametes. Sporophyte is the plant body which produces spores. Spores form the
gametophyte. Hence, cells of gametophyte are haploid and cells of sporophyte are diploid.

Vascular tissue is a complex conducting tissue found in vascular plants.
