1. Agameon
An organism that reproduces asexually only, without producing gamete s ( sperm or egg s).

2. Allogamy (adj. allogamous)
Synonym for cross-fertilization; this is the combining of gamete s derived from different individuals.

3. Anisogamy
A condition where the gamete s of a species have different sizes. In general, the smaller, more mobile gamete is "male" and the larger one which is packed with food and other things to give the potential zygote a good start (and is less mobile as a result) is the "female." The principle behind anisogamy is a division of the labor necessary for two gametes to unite and successfully develop.

4. Antheridium
The fertile organ of a male gametophyte or the male organ of a bisexual gametophyte, in which male gametes are formed.

5. Archegonium
The structure on the pteridophyte prothallus that produces the sessile female gamete s. Compare antheridium .

6. Cell fusion
The process in which two different cell s fuse into one single cell. The resulting cell has all of the contents from the original cells and has one nucleus containing the genetic material from both of the original cells. This occurs naturally during sexual reproduction , when gamete s ( egg s and sperm ) fuse to produce the zygote , and can also occur under laboratory conditions between somatic cells (any cell other than a gamete).

7. Chlamydomonas
A genus of green algae consisting of more than 600 species worldwide, living in marine, freshwater, soil, and even snow environments. They are single cell ed eukaryotic organisms ranging from 5 to 100 micrometers long which can be roughly spherical, egg shaped, or elliptical. Most species have two flagella (coming out the same side) for swimming. Most of the time they are haploid and reproduce by dividing into two ( binary fission ); when they are stressed they can form gamete s which fuse to form diploid cyst s which later divide into four haploid cells. Taxonomically they have been classified under plants, animals, and protist s. Several species from this genus are important model organisms for the study of cell biology , molecular biology , genetics , plant physiology , and biotechnology . The species most commonly used in scientific experiments is Chlamydomonas reinhardtii (also known as C. reinhardi or C. reinhardii).

8. Diploid
A full set of genetic material, consisting of paired chromsome s one chromosome from each parental set. Most animal cells except the gamete s have a diploid set of chromosomes. The diploid human genome has 46 chromosomes. Compare haploid .

9. Endogamy
The opposite of exogamy : * Sexual reproduction between organism s which are closely related to each other. * Production of a zygote (an egg that has been fertilized by a sperm ) by a simultaneous hermaphrodite (an organism which produces both sperm and eggs) using only its own gamete s (eggs and sperm) without gamete contributions from other individuals. * Marriage between members of the same restricted group, class, or caste.

10. F protein
A protein derived from the Sendai virus which can be used in the laboratory to cause cell fusion between somatic cell s (any cell that is not a gamete ). It is also used to make fusogenic vesicle s.
