Detailed explanation-1: -Answer: Bryophytes are the plants in which the life cycle has two phases gametophytic and sporophytic, alternating to each other. This phenomenon is called alternation of generation.

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. The ability of the plants to reproduce sexually and asexually helps them to adapt to different environments.

Detailed explanation-3: -Characteristics of Kingdom Plantae They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes.

Detailed explanation-4: -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-5: -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.
