DENDROLOGY

Detailed explanation-1: -Alternation of generation is defined as the alternation of multicellular diploid (sporophyte ) and haploid form (gametophyte) in the organism’s life cycle. This is a characteristic feature of Kingdom Plantae.

Detailed explanation-2: -Plants alternate between the diploid sporophyte and haploid gametophyte, and between asexual and sexual reproduction. Therefore, the life cycle of plants is known as alternation of generations.

Detailed explanation-3: -The alternation of generations allows for both the dynamic and volatile act of sexual reproduction and the steady and consistent act of asexual reproduction. When the sporophyte creates spores, the cells undergo meiosis, which allows the gametophyte generation to recombine the genetics present.

Detailed explanation-4: -Answer and Explanation: The characteristic that is common to all vascular plants that exhibit an alternation of generations in their life cycle is b) Multicellular sporophytes.
