Reproduction reproductive system and sex cells

The human body and reproduction involve highly personal information and topics. This page and all pages on this site are intended to supplement instruction and guidance from parents, schools and other responsible community organizations. The reproductive system is responsible for the creation of new life. Humans have sexual reproduction.

Reproduction reproductive system and sex cells

The parents have sex organs which produce sex cells or gametes.

Anatomy of the Male Reproductive System

The male gamete is sperm and the female gamete is the egg. Sexual reproduction is the fusion or fertilisation of the two male and female gametes to produce a fertilised egg or zygote The fertilised egg goes on to divide many times to form a ball of cells.

This grows into an embryo which eventually develops into a separate individual. Sex Cells Gametes Sperm Cell Sperm are highly specialised cells that contain that carry the genetic material of the male.

A sperm cell has three main parts: In the head of the sperm is the nucleus which contains chromosomes ie the genetic information from the father. The tail of the sperm plays an important role as it beats and helps drive the sperm forward and swim towards the egg. Egg Cell An egg cell is the female sex cell.

In term of size it is much bigger than the sperm.

It also has a nucleus which contains the female genetic information. Fertilisation occurs when the nucleus of the sperm joins with the nucleus of the egg. Comparison of the sex cells Sperm cell.female reproductive apparatus; internal female genital organs / organa genitalia feminina interna: the various organs in the female that are concerned with reproduction; adnexa uteri; epoöphoron / epoophoron / corpus pampiniforme / pampiniform body / parovarium / Rosenmüller's organ: a vestigial structure associated with the ovary, consisting of a more cranial group of mesonephric tubules.

The reproductive system is a collection of internal and external organs — in both males and females — that work together for the purpose of procreating, according to the Cleveland timberdesignmag.com Human cells come in a variety of shapes and sizes, and carry out a wide range of different functions.

But the largest and smallest cells in the human body are both gametes, or reproductive cells.

Sexual Reproduction

The offspring formed by sexual reproduction contain genes from both parents and show considerable variation. For example, kittens in a litter are all different although they (usually) have the same mother and father. In the wild this variation is important because it means that when the environment.

Reproduction reproductive system and sex cells

The human reproductive system is different in males and females. When a sperm and egg join, the egg is fertilised and a baby starts to develop. All living things reproduce.

Reproduction — the process by which organisms make more organisms like themselves — is one of the things that set living things apart from nonliving matter.

But even though the reproductive system is essential to keeping a species alive, unlike other body systems it.
