NEET BIOLOGY

Detailed explanation-1: -Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.

Detailed explanation-2: -The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant.

Detailed explanation-3: -In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis.

Detailed explanation-4: -There are three different plant life cycles: haploid (1n), diploid (2n), and the more common haploid-diploid (1n-2n). A haploid organism consists of a multicellular structure of cells that contain only one set of chromosomes, whereas, a diploid organism’s multicellular stage contains two sets of chromosomes.
