Flowering Plants: Reproduction
Ch. 39 Bio
Terms in this set (52)
A process that requires a fertilization event in which two gametes unite to produce a cell called a zygote.
The diploid generation of plants or multicellular protists that have a sporic life cycle; this generation produces haploid spores by the process of meiosis.
In plants and many multicellular protists, the haploid stage that produces gametes by mitosis.
A flower organ that occurs in a whorl located outside whorls of petals of eudicot plants.
A flower organ that usually serves to attract insects or other animals for pollen transport.
A flower organ that produces the male gametophyte, pollen.
A flower shoot organ that produces ovules that contain female gametophytes.
A haploid multicellular plant life cycle stage that produces sperm.
1. The elongate portion of a flower's stamen: contains vascular tissue that delivers nutrients from parental sporophytes to anthers. 2. In fishes, a part of the gills.
The uppermost part of a flower stamen, consisting of a cluster of microsporangia that produce and release pollen.
In seed plants and some seedless plants, a relatively small spore that produces a male gametophyte within the spore wall.
The immature male gametophyte of a seed plant.
A haploid multicellular plant generation that produces one or more eggs but does not produce sperm cells.
A flower structure that may consist of a single carpel or multiple, fused carpels and is differentiated into stigma, style, and ovary.
In a flower, the topmost portion of the pistil, which receives and recognizes pollen of the appropriate species or genotype.
In a flower, the elongate portion of the pistil through which the pollen tube grows.
1. In animals, the female gonad where eggs are formed. 2. In plants, the lowermost portion of the pistil that encloses and protects the ovules.
In a seed plant, a megaspore-producing megasporangium and enclosing tissues known as integuments.
In plants, a structure that encloses the megasporangium to form an ovule.
In seed plants and some seedless plants, a large spore that produces a female gametophyte within the spore wall.
The process in which pollen grains are transported to an angiosperm flower or a gymnosperm cone primarily by means of wind or animal pollinators.
The process in which pollen from the anthers of a flower is transferred to the stigma of the same flower or between flowers or the same plant.
The process in which a stigma receives pollen from a different plant of the same species.
In seed plants, a long, thin tube produced by a pollen grain that delivers sperm to the ovule.
A small opening in the integument of a seed plant ovule through which a pollen tube grows.
The union of two gametes, such as an egg cell with a sperm cell, to form a zygote.
In angiosperms, the process in which two different fertilization events occur, producing both a zygote and the first cell of a nutritive endosperm tissue.
A diploid cell formed by the fusion of two haploid gametes.
A hard and tough covering that develops from the ovule's integuments and protects a plant embryo.
The wall of a plant's fruit.
In plants, the process in which an embryo absorbs water, becomes metabolically active, and grows out of the seed coat, producing a seedling.
In a flower, concentric rings of sepals and petals (or tepals), stamens, and carpels.
The term that refers to flower petals and sepals collectively.
The term to describe plants that produce carpellate and staminate flowers on the same plant.
The term to describe plants that produce staminate and carpellate flowers on separate plants.
A cluster of flowers in a plant.
In a seed plant, one of the cells resulting from the division of a microspore; a generative cell divides to produce two sperm cells.
In a seed plant, one of the cells resulting from the division of a microspore; stores proteins and forms the pollen tube.
The reproductive state of plants that can serve as both mother and father to their progeny.
Rejection of pollen that is genetically too similar to the pistil of a plant.
In the female gametophyte of a flowering plant, the two cell adjacent to the egg cell that help to import nutrients from maternal sporophyte tissues.
In the female gametophyte of a flowering plant, a large cell that contains two nuclei; after double fertilization, it forms the first cell of the nutritive endosperm tissue.
The process by which embryos develop from single-celled zygotes by mitotic divisions.
A short chain of cells at the base of an early angiosperm embryo that provides anchorage and nutrients.
An embryonic seed leaf.
The portion of an embryonic plant stem with two tiny leaves in a first bud; located above the point of attachment of the cotyledons.
The portion of an embryonic plant stem located below the point of attachment of the cotyledons.
An embryonic root, which extends from the plant hypocotyl.
A protective sheath that enclosed the first bud of the epicotyl in a mature monocot embryo.
A protective envelope that encloses the young root of a monocot.
A reproductive strategy that occur when offspring are produced from a single parent, without the fusion of gametes from two parents. The offspring are therefore clones of the parent.
The production of plant embryos from body (somatic) cells.
