Answer 1

Answer:

B. a - (ii) ,b - (iv) ,c - (i), d - (iii)

(a) Haplontic refers to organisms that have a single set of chromosomes (haploid) for most of their life cycle. Chara (ii) is a haplontic organism.

(b) Diplontic refers to organisms that have two sets of chromosomes (diploid) for most of their life cycle. Sargassum (iv) is a diplontic organism.

(c) Haplobiontic refers to organisms that have a life cycle with both haploid and diploid phases, but the haploid phase is dominant. Batrachospernum (i) is a haplobiontic organism.

(d) Diplobiontic refers to organisms that have a life cycle with both haploid and diploid phases, but the diploid phase is dominant. Polysiphonia (iii) is a diplobiontic organism.
