alternations fo generations
Life cycle, typical of plants, in which a diploid sporophyte alternates with a haploid gametophyte.
Flowering plant that produces seeds within an ovary, which eventually develops into a fruit.
In flowering plants, pollen-bearing portion of the stamen.
Sperm-producing structure, as in the moss life cycle.
Egg-producing structure, as in the moss life cycle.
the sepals collectively; the outermost flower whorl
ovule bearing unit that is a part of a pistil
Type of seedless vascular plants that are also called ground pines.
Cone-bearing gymnosperm plants that include pine, cedar, and spruce trees.
The petals, collectively; usually the conspicuously colored flower whorl.
Type of gymnosperm with palmate leaves and massive cones.
Member of a group of plants that have large fronds.
End-to-end chains of cells that form as cell division occurs in only one plane; in plants, the elongated stalk of a stamen.
In a flowering plant, the structure that forms from an ovary and associated tissues and encloses seeds.
Haploid generation of the alternation of generations life cycle of a plant; produces gametes that unite to form a diploid zygote.
on of four phyla of gymnosperms
Division of plants composed of three related woody gymnosperms.
Type of woody seed plant in which the seeds are not enclosed by fruit and are usually borne in cones, such as those of the conifers.
Member of a seedless vascular plant phylum that has only one genus (Equisetum) in existence today.
type of bryophyte
type of bryophyte
Bryophytes such as mosses and liverworts that have no vascular tissue and either occur in moist locations or have special adaptations for living in dry locations.
In animals, the female gonad, the organ that produces oocytes, estrogen, and progesterone; in flowering plants, the base of the pistil that protects ovules and, along with associated tissues, becomes a fruit.
In seed plants, a structure where the female megaspore becomes an egg-producing female gametophyte that develops into a seed following fertilization.
A flower part just inside the sepals; often conspicuously colored to attract pollinators.
Vascular tissue that conducts organic solutes in plants.
One of two types of cones produced by gymnosperms; contains windblown pollen (male gametophyte).
In seed plants, the sperm-producing male gametophyte.
In seed plants, a tube that forms when a pollen grain lands on the stigma and germinates. The tube grows to reach the egg inside an ovule, where fertilization occurs.
In seed plants, the delivery of pollen to the vicinity of the egg-producing female gametophyte.
Area where a flower attaches to a floral stalk.
Mature ovule that contains a sporophyte embryo with stored food enclosed by a protective coat.
One of two types of cones produced by gymnosperms; contains windblown seeds (female gametophyte).
Outermost, sterile, leaflike covering of the flower; usually green in color.
Haploid reproductive cell, sometimes resistant to unfavorable environmental conditions, which is capable of producing a new individual that is also haploid.
Diploid generation of the alternation of generations life cycle of a plant; produces haploid spores that develop into the haploid generation.
In flowering plants, the portion of the flower that consists of a filament and an anther containing pollen sacs where pollen is produced.
In flowering plants, portion of the pistil where pollen grains adhere and germinate before fertilization can occur.
Elongated, central portion of the pistil between the ovary and the stigma.
Plant that has vascular tissue (xylem and phloem); includes seedless vascular plants (e.g., ferns) and seed plants (gymnosperms and angiosperms).
Transport tissue in plants, consisting of xylem and phloem.
Vascular tissue that transports water and mineral solutes upward through the plant body; contains vessel elements and tracheids.
