Practical Report on human sexual reproduction.

BIOLOGY 2: PRACTICAL REPORT HUMAN in take inal REPRODUCTION Re work is the generation of tonic psyches of the same(p) species. In a familiar procreation individuals ar derived from one invoke and no special fruitful structures are involved. The simplest constellation is fission, occurring for the most activate 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 ii or more parts, each capable of growth to ashes a new individual; this is seen in flatworms and algae. Most animals save 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 form diploid zygote. The fe potent gamete, oram (unfe rtilized 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 inflorescence plants and the ovary and testes in animals. The immenseness of sexual reproduction in disposition is that it allows genetic interlingual rendition in a population, which is therefore bring out able to lodge to the changing environment.

Part A : IDENTIFYING THE organs OF THE MALE AND FEMALE procreative SYSTEMS i)The male reproductive placement The process of Meiosis occurs i! n the organ called the testes. The two testes are located in a at large(p) pouch of pelt 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...
