Dictionary » S » Spermatozoon



noun, plural: spermatozoa

A mature male gamete or reproductive cell; sperm cell.


A single sperm cell or spermatozoon consists of a round or cylindrical nucleated cell, a short neck, and a thin motile tail. Its structure is vital to its mobility and function (i.e. sexual reproduction). The compacted nucleus contains half of the genetic information. It fuses with an ovum (the female gamete) to form a zygote. In mammals, the sex is determined by the sperm cell. If it bears Y chromosome, the resulting offspring is a male. If X chromosome, the offspring is a female.

Word origin: Greek, from sperma, spermat-, seed + New Latin -zōon, from Greek zōion, zōon, living being.
Related forms: spermatozoal, spermatozoic (adjective).

Variant: spermatozoan.
Also called: sperm cell, zoosperm.

... system. All it has are two nerve cells which can be any kind of cells (motor, sensor, both, etc.). Any thoughts on the subject? I think it is spermatozoon, it fulfills the criteria of "moving" and "living from glucose" but it seems that the rest statement are not suitable :D
