Question

Which of the following statements is true about alternation of generation in pteridophytes?

• A. Diploid generation is followed by a triploid generation.
• B. Haploid generation is followed by a diploid generation.
  
• C. Triploid generation is followed by a haploid generation.
  
• D. Diploid generation is followed by a haploid generation.
  

Answer 1

The correct option is D Diploid generation is followed by a haploid generation.

The life cycle of pteridophytes involves alternation of generations. This means that a diploid generation (the sporophyte, which produces spores) is followed by a haploid generation (the gametophyte or prothallus, which produces gametes).

So, the correct answer is 'Diploid generation is followed by haploid generation'.
