    en.wikipedia.org/wiki/Alternation_of_generations

    Two single-celled haploid gametes, each containing n unpaired chromosomes, fuse to form a single-celled diploid zygote, which now contains n pairs of chromosomes, i.e. 2n chromosomes in total. [17] The single-celled diploid zygote germinates, dividing by the normal process , which maintains the number of chromosomes at 2n.

    "Experiments on Plant Hybridization" (German: Versuche über Pflanzen-Hybriden) is a seminal paper written in 1865 and published in 1866 [1] [2] by Gregor Mendel, an Augustinian friar considered to be the founder of modern genetics.

  6. Diploidization - Wikipedia

    en.wikipedia.org/wiki/Diploidization

    The resolution of these structures results in chromosome breakage, rearrangement, and gamete infertility. Diploidization is often required to restore the cell’s ability to stably go through meiosis. [2] Reduce costs of maintaining large, duplicated genomes Large genomes are costly to synthesize during replication and hard to maintain. [2]

  7. Biological life cycle - Wikipedia

    en.wikipedia.org/wiki/Biological_life_cycle

    Haploid cells may divide again (by mitosis) to form more haploid cells, as in many yeasts, but the haploid phase is not the predominant life cycle phase. In most diplonts, mitosis occurs only in the diploid phase, i.e. gametes usually form quickly and fuse to produce diploid zygotes. [14] In the whole cycle, gametes are usually the only haploid ...

  8. Embryonic sac - Wikipedia

    en.wikipedia.org/wiki/Embryonic_sac

    A megaspore mother cell, or megasporocyte, is a diploid cell in plants in which meiosis will occur, resulting in the production of four haploid megaspores. At least one of the spores develop into haploid female gametophytes, the megagametophytes. [1] The megaspore mother cell arises within the megasporangium tissue.

  9. Plant cell - Wikipedia

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
