Sexual Reproduction In Animals, Gametogenesis Class 10 In Urdu Hindi By Mr.Hadi #Spermatogenesis #Oogenesis MCQs of this topic is present at the end of the lecture. ............................................................................................................................... Sexual Reproduction in Animals: Sexual reproduction is the production of a new organism from two parents by making use of their sex cells or gametes. In this process male gametes fuses with a female gamete to form a new cell called ‘zygote’. This zygote then grows and develops in to a new organism in due course of time. Sometimes sex cells or gametes are also called as germ cells. The humans, fish, frogs, cats, dogs etc. all reproduce by the method of sexual reproduction. Sexual reproduction is the production of a new organism from two parents by making use of their sex cells or gametes. The humans, fish, frogs, cats and dogs, all reproduce by the method of sexual reproduction. It is important to know the meaning of some important terms like male sex, female sex, gametes, sperms, ova or eggs, fertilization, zygote and embryo which are involved in sexual reproduction. An animal having male sex cells called ‘sperms’ in its body is called male and an animal having female sex cells called ‘ova’ or ‘eggs’ in its body is called female. Gonads: Gonads are the male and female primary reproductive organs. The male gonads are the testes and the female gonads are the ovaries. These reproductive system organs are necessary for sexual reproduction as they are responsible for the production of male and female gametes. Gametes: The cells involved in sexual reproduction or we can say that they are sexual reproductive cells. They are of two types: male gametes and female gametes. The male gamete in animal is called ‘sperm’ and the female gamete in animals is called ‘ovum’ or ‘egg’. Also female gamete or female sex cell is known by two names: ovum and egg both are same. The plural of ovum is ova. The ovum or egg contains water and stored food. Nucleus is the important part of ovum. Sperm cells are hundreds or thousands time smaller than ovum or egg and have a long tail. The sperm are motile which can move independently with the help of their tails. ........................................................................................................................................
