of one cell and they do not have a nucleus but a loop of DNA. When bacteria‚ reproduce asexually the DNA loop is copied so that there is some for each new cell. The bacterial cell deivides into two by making a new cell wall. This type of asexual reproduction is called binary fission. Spore Production in Fungi Pin mould is a fungus which grows on bread and reproduces asexually by making spores. They are small and light like spects of dust‚ and float through the air.

Introduction to sexual reproduction in humans Reproduction is the process by which humans gives rise to new individuals. Sexual reproduction is the process that involves the fusion of two gametes‚ sperm (male gamete) and egg (female gamete). In human these gametes are produced in different sexes‚ the male and female. Reproduction in humans is performed by reproductive systems‚ the male and female reproductive systems. The main organs of male reproductive system are testis and gonads and of female

Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. In asexual reproduction‚ an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of

Asexual Reproduction in Animals Group 3 Nina Bansil Kenneth Calabia Josef Franz Cruz I. Introduction Asexual reproduction is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. Only one parent is involved in asexual reproduction. A more stringent definition is agamogenesis which refers to reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚ bacteria‚ and protists

Re 7B Reproduction About the Unit This Unit covers human reproduction and development. The Unit starts with an overview of what reproduction is and considers different modes of reproduction in animals. Human reproductive organs are then covered‚ along with adaptations of sex cells. This is followed by a look at sexual intercourse‚ the menstrual cycle‚ pregnancy and birth. The Unit ends with puberty and adolescence‚ a stage which many pupils will be going through or just about to

Parthenogenesis vs. Sexual Reproduction Jorge Pablo Velasco Borda Introduction: Parthenogenesis is a type of reproduction in which the sperm does not fertilized the ovum. In parthenogenesis some chemical agents fertilize the ovum most of times because the female does not have a male to have sex with. That’s the case of Flora a Komodo dragon that live at the Chester Zoo in England (Chiang. M). Flora gave birth to seven babies without having a male. Sexual reproduction is when a sperm fertilize
