NEET BIOLOGY

Detailed explanation-1: -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-2: -Alternation of generations means that plants alternate between two different life stages, or generations, in their life cycle; a haploid stage called gametophyte and a diploid stage called sporophyte. The terms haploid and diploid refer to the number of chromosomes contained in the cells.

Detailed explanation-3: -alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism.

Detailed explanation-4: -The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.

Detailed explanation-5: -Land plants all have heteromorphic (anisomorphic) alternation of generations, in which the sporophyte and gametophyte are distinctly different.
