Difference between Fish reproduction and Sperm

Fish reproduction vs. Sperm

Fish reproductive organs include testes and ovaries. Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) sperma (meaning "seed").

Cell (biology)

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms.

Cell nucleus

In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-enclosed organelle found in eukaryotic cells.

Egg cell

The egg cell, or ovum (plural ova), is the female reproductive cell (gamete) in oogamous organisms.

Epididymis

The epididymis (plural: epididymides or) is a tube that connects a testicle to a vas deferens in the male reproductive system.

Fertilisation

Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, conception, fecundation, syngamy and impregnation, is the fusion of gametes to initiate the development of a new individual organism.

Gamete

A gamete (from Ancient Greek γαμετή gamete from gamein "to marry") is a haploid cell that fuses with another haploid cell during fertilization (conception) in organisms that sexually reproduce.

Gametophyte

A gametophyte is one of the two alternating phases in the life cycle of plants and algae.

Meiosis

Meiosis (from Greek μείωσις, meiosis, which means lessening) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

Oocyte

An oocyte, oöcyte, ovocyte, or rarely ocyte, is a female gametocyte or germ cell involved in reproduction.

Sexual reproduction

Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm.

Spermatogenesis

Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.

Spermatozoon

A spermatozoon (pronounced, alternate spelling spermatozoön; plural spermatozoa; from σπέρμα "seed" and ζῷον "living being") is a motile sperm cell, or moving form of the haploid cell that is the male gamete.
