Cilia

anisogamete
The condition of having anisogametes.
anisogamy
The part of the stamen of a flower that bears the pollen.
anther
An organ in simpler plants that produces sperm cells.
antheridium
An organ in lower vascular plants, gymnosperms, mosses, and liverworts which produces an egg cell.
archegonium
A reproductive organ of gymnosperms having a central axis with radiate scales and bracts. A cone can either produce pollen or ovules.

An act of fertilization involving the transfer of cell contents to another cell. Conjugation usually occurs in simpler organisms.
conjugation
A large gamete with stored food.
egg

flagellum
An organ of lower plants, some protists and some fungi that produces gametes.
gametangium
Gamete producing organs in animals
gonad
Cone-bearing plant. Often called evergreen.
gymnosperm
Incapable of independent movement.
immotile
Gametes that are the same in size and shape.
isogamete
Capable of independent movement.
motile
Having gametes of different size and shape. Usually oogamous organisms have eggs and sperm.
oogamous
The condition of being oogamous.
oogamy
The female gonad in animals. It produces eggs. Also, in plants it is the lower portion of the pistil that contains ovules and develops into fruit.
ovary
The egg cell; a female gamete.
ovum

sperm
The male organ of plants. It produces pollen.
