Alternation of generations
The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations
The asexual and usually diploid phase, producing spores from which the gametophyte arises
The gamete-producing and usually haploid phase, producing the zygote from which the sporophyte arises
Bryophytes are an informal group consisting of three divisions of non-vascular land plants, the liverworts, hornworts and mosses
Vascular Tissue
The tissue in higher plants that constitutes the vascular system, consisting of phloem and xylem, by which water and nutrients are conducted throughout the plant
The female sex organ in mosses, liverworts, ferns, and most conifers.
The male sex organ of algae, mosses, ferns, fungi, and other nonflowering plants.
A receptacle in which asexual spores are formed.
Large group of plants that are defined as those land plants that have lignified tissues for conducting water and minerals throughout the plant
A type of water-conducting cell in the xylem that lacks perforations in the cell wall
The vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem
The vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves
A flowering plant's unit of reproduction, capable of developing into another such plant
Group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes
The flowering plants, also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants
Pollen Grain
Pollen grains have a tough coat that has a form characteristic of the pollen-producing plant and which can still be recognized in some archaeological deposits
The act of transferring pollen grains from the male anther of a flower to the female stigma
Seed Coat
The protective outer coat of a seed.
The part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed
Pollen Tube
A hollow tube that develops from a pollen grain when deposited on the stigma of a flower. It penetrates the style and conveys the male gametes to the ovule
The hollow base of the carpel of a flower, containing one or more ovules
Fruit is the seed-bearing structure in flowering plants formed from the ovary after flowering
A cotyledon is a significant part of the embryo within the seed of a plant
Flowering plants whose seeds typically contain only one embryonic leaf, or cotyledon
One of the two groups into which all the flowering plants or angiosperms were formerly divided
Woody Plant
Plant that produces wood as its structural tissue
Herbaceous Plant
Plants that have no persistent woody stem above ground
