NEET BIOLOGY

Detailed explanation-1: -Organisms belonging to pteridophytes, gymnosperms angiosperms and most of the animals including human beings.

Detailed explanation-2: -Solution : Organisms belonging to pteridophytes, gymnosperms, angiosperms and most of the animlas including human beings, the parental body in diploid. <br> Meiosis, the reduction division, has to occur if a diploid body has to produce haploid gametes.

Detailed explanation-3: -Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as “cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes.

Detailed explanation-4: -Haploid refers to the presence of a single set of chromosomes in an organism’s cells. Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only the egg and sperm cells are haploid.

Detailed explanation-5: -In pteridophytes, gymnosperms and angiosperms the parental body is diploid.
