Ovule
|
A structure that develops within the ovary of a seed plant and contains the female gametophyte.
|
|
Flower
|
In an angiosperm, a short stem with up to four sets of modified leaves, bearing structures the function in sexual reproduction.
|
|
Anther
|
In an angiosperm, the terminal pollen sac of a stamen, where pollen grains with male gametes form.
|
|
Embryo Sac
|
The female gametophyte of angiosperms, formed from the growth and division of the megaspore into a multicellular structure with eight haploid nuclei.
|
|
Seed
|
An adaptation for terrestrial plants sonsisting of an embryo packaged along with a store oof food within a resistant cell.
|
|
Sepal
|
A modified leaf in angiosperms that helps enclose and protect a flower bud before it opens.
|
|
Stigma
|
The sticky part of a flower's carpel, which traps pollen grains.
|
|
Cross Pollination
|
In angiosperms, the transfer of pollen from the anter of a flower on one plant to the stigma of a flower of another plant of the same species.
|
|
Conifer
|
A member of the largest gymnosperm phlyum. Most are cone-bearing tress, such as pines and firs.
|
|
Petal
|
A modified leaf of a flowering plant. Often the colorful parts of a flower that advertise it to insects and other pollinators.
|
|
Style
|
The stalk of a flower's carpel, with the ovary at the base and the stigma at the top.
|
|
Cotyledons
|
A seed leaf of an angiosperm embryo. Some species have one, others two.
|
|
Tracheids
|
A long, tapered water-conducting cell that is dead at maturity and is found in the xylem of all vascular plants.
|
|
Stamen
|
The pollen-producing reproductive organ of a flower, consisting of an anther and filament.
|
|
Ovary
|
In flowers, the portion of a carpel in which the egg-containing ovules develop.
|
|
Endosperm
|
A nutrient-rich tissue formed by the union of sperm cell with two polar nuclei during double fertilization, which provides nourishment to the developing embryo in angiosperm seeds.
|
|
Vessel Elements
|
A short, wide, water-conducting cell found in the xylem of most angiosperms and a few nonflowering vascular plants.
|
|
Carpel
|
The ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary.
|
|
Fruit
|
A mature ovary of a flower that protects dormant seeds and aids in their dispersal.
|
|
Double Fertilization
|
A mechanism of fertilization in angiosperms, in which two sperm cells unite with two cells in the embryo sac to form the zygote and endosperm.
|
|
Filament
|
The stalk of a stamen.
|
|
Pollen Grains
|
The structures that contain the male gametophyte of seed plants.
