Similarly the wastes from developing embryo are removed to mother’s blood through placenta. The semen is discharged into the vaginal tract during copulation. Petals are colourful and attract the insects for pollination. The flowers may be bisexual i.e. Therefore, they can reproduce by complex reproductive methods such as vegetative propagation, spore formation, etc. Testes produce sperms and hormone, Testosterone hormone. These are called secondary sexual characters. It needs sexual maturation which includes the creation of the germ cells, i.e., egg (ova) in the female and sperm in the male partner and this period of sexual maturation is called Puberty. The embryo gets nutrition from the mother’s blood with the help of a special tissue called placenta, which is a disk-like structure embeded in the uterine wall. Name * Email * Website. The process of DNA copying leads to variations. The egg is carried from the ovary to the womb through a fallopian tube. These organisms reproduce by binary fission; especially when conditions are favourable, i.e. Also, reproduction is one of the distinctive characteristics of living things that separate … They are produced during unfavourable times and help to tide over the unfavourable environmental conditions. (i) Binary Fission: Seen in bacteria, protozoa like Amoeba, Paramecium. Pollen tube releases two male germ cells inside the ovule, one of them fuses with female germ cell and forms a zygote which grows into the baby plant i.e. Sugarcane, jasmine by stems and Biyophyllum by leaves.

Function of the fallopian tubes: It is the site of fertilization between the male and the female gametes and formation of the zygote early embryo. So in flowering plants two fusions take place during fertilisation. The nucleus divides, and each daughter nuclei is surrounded by a membrane. If it does not get zygote, the developed lining slowly breaks down and comes out through the vagina as blood and mucus. This process is called Menstruation. Testosterone brings about changes in appearance of boys at the time of puberty. Uterus: The two oviducts unite into an elastic bag like structure known as the uterus. The narrow end of the uterus is called cervix. In this during unfavourable conditions, the parent cell develops a thick resistant wall around itself forming a cyst. If the egg is not fertilized, if lives for about one day since the ovary releases one egg every month, the uterus prepares itself every month to receive the fertilized egg. This chapter primarily discusses the reproductive system in living organisms and the types of reproductive systems, in particular.
