Sepals |
The members of the outermost floral whorl. Often green and protect the flower buds. |
|
|
|
Seed |
Reproductive structure composed of an embryo, nutritive materials, and a protective coat. |
|
|
|
Pollination |
Transfer of pollen from one another to the stigma in angiosperms. |
|
|
|
Pollen Grain |
The immature male gametophyte in angiosperms and gymnosperms, at the stage when it is shed from the plant that produces it. |
|
|
|
Petals |
The floral component consisting of modified leaflike structures which are brightly colored to attract insects or other animals |
|
|
|
Heterosporous |
Refers to a vascular plant that produces both microspores and megaspores |

|
|
Frond |
The leaf of a fern |

|
|
Endosperm |
The usually triploid food supply of an angiosperm.v |

|
|
Primary Endosperm Nuclei |
The triploid nucleus resulting from the fusion of a single sperm with the two polar nuclei. |
|
|
|
Fruit |
A ripened ovary or group of ovaries, often with other adhering flower parts. |
|
|
|
Megaspore |
A haploid cell that will develop into a female gametophyte in heterosporous plants. |
|
|
|
Megasporocyte |
A diploid cell that will divide by meiosis to produce four haploid megaspores, usually only one of which is functional in seed plants. Also called a megaspores mother cell. |
|

Antipodal Cells |
A component of the eight-nucleate embryo sac in angiosperms, which usually are three in number |
|
|
|
Archegonium |
A multicellular structure on the gametophyte, in which an egg is produced. |
|
|
|
Antheridium |
The male sperm-producing structure of a gametophyte, found in seedless and some seed plants. |
|
|
|
Micropyle |
The opening in the integument of an ovule through which the pollen tube grows. |
|
|
|
Stigma |
The uppermost pollen-receptive portion of a carpel. |
|
|
|
Sporophyte |
The multicellular, diploid phase of a plant. |
|
|
|
Microsporocyte |
A diploid cell that will divide by meiosis, producing four haploid microspores. Also called a microscope mother. |
|
|
|
Ovary |
The lower swollen part of a carpel; contains the ovules and develops into the fruit. |
|
|
|
Homosporous |
Refers to a vascular plant that produces only one type of spore. |
