Statement A : Ectocarpus, porphyra , kelps are haplo-diplontic Statement B : The diploid sporophyte is represented by a dominant, independent, photosynthetic, vascular plant body in pteridophytes.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Ectocarpus, Polysiphonia, kelps are haplo-diplontic

Meiosis can take place in
1 Only haploid species
2 Only diploid species
3 Both in haploid as well as diploid species
4 Only triploid species
Explanation:
Meiosis or reduction division can take place only in diploid or species with an even ploidy number. This is because haploid ploidy cannot be reduced any further. Also, odd number of ploidy cannot be equally divided.
