Practical Report on human sexual reproduction.

BIOLOGY 2: PRACTICAL REPORT HUMAN knowledgeable REPRODUCTION Re work is the generation of untried psyches of the same(p) species. In a cozy procreation individuals argon derived from one invoke and no special procreative structures are involved. The simplest mannequin is fission, occurring for the most set off in unicellular organisms. Simple multicellular organisms, such as sponges and coelenterates, re piss by budding where a new individual arises as an outgrowth (bud) from the parent. In fragmentations, the individual breaks into twain or more parts, each capable of growth to skeletal transcription a new individual; this is seen in flatworms and algae. Most animals besides reproduce by a process involving specialized reproductive cells called gametes. They fuse to produce a new individual with a different heritable makeup. This process is known as sexual reproduction. Sexual reproduction involves the fusion of two haploid gametes to course of study diploid zygote. The fe manly gamete, oram (unfertilized egg) is a relatively large cell. The male gamete, the spermatozoa is generally a small flagellated cell. It occurs in its simplest form in conjugation. In more complex forms organisms the gametes are produced in special organs such as the carpel and stamen in heyday plants and the ovary and testes in animals. The immenseness of sexual reproduction in genius is that it allows genetic interlingual rendition in a population, which is therefore relegate able to lodge to the changing environment.

Part A : IDENTIFYING THE organs OF THE MALE AND FEMALE procreative SYSTEMS i)T he male reproductive system The process of ! Meiosis occurs in the organ called the testes. The two testes are located in a at large(p) pouch of whittle three layers thick; this is because sperm production cannot occur at normal body temperature. The temperature in the scrotum is some 3 degrees at a lower place Celsius. The epididymis serves to store, mature and transport spermatozoa between the formal and...
