Plants: Essential Processes Terms Gametophyte - A haploid plant or plant structure that produces haploid gametes through mitosis. Grafting - An artificial form of vegetative propagation in which parts of two young plants are joined together, first by artificial means and then by tissue regeneration. Gymnosperm - A vascular non-flowering plant (commonly known as a conifer) in which seeds are not protected by an ovary. Haploid - Having only one set of chromosomes. Heterospory - The reproductive phenomenon, characteristic of gymnosperms and angiosperms, whereby spores of two distinct sexes are produced; these spores develop into sex-specific gametophytes. Megaspore - Female spore; gives rise to a female gametophyte. Meiosis - Cell division that results in cells with half the chromosomes of the parent cell. Microspore - Male spore; gives rise to a male gametophyte.

Unformatted text preview: Ovary - In plants, the protective structure that holds the ovules and surrounds the angiosperm seed; after fertilization, develops into a fruit. Ovule - Structure that contains the female gametophyte and gametes; after fertilization, develops into a seed. Pistil - The female reproductive organ of the flower, composed of a stigma, style, and ovary; sometimes called the carpel. Polar Nuclei - Two nuclei, contained within the same cell, that are created from the mitotic division of the megaspore during angiosperm reproduction; unite in the ovule to form a fusion nucleus, which gives rise to endosperm when fertilized. Pollen Grain - The male gametophyte of gymnosperms and angiosperms. Pollen Tube - The outgrowth of a pollen grain that creates a path through the female sex organ in order to penetrate to the egg cells....
