Reproduction in Animals Video Lecture - Class 8

0:0:0: reproduction in
0:0:3: animals think about the young ones you
0:0:5: have seen being
0:0:7: born chicks kittens and
0:0:11: puppies have you ever wondered how they
0:0:14: come into the
0:0:16: world do they look the same before birth
0:0:19: as they do now let's explore these
0:0:21: intriguing questions
0:0:23: together the ability to produce more
0:0:25: organisms similar to themselves is very
0:0:28: important for all living beings
0:0:31: the process by which they do so is
0:0:33: called
0:0:34: reproduction it plays a crucial role in
0:0:36: maintaining the cycle of life on Earth
0:0:39: so by definition reproduction is the
0:0:42: biological process by which new
0:0:44: individuals of the same kind are
0:0:47: produced it is essential as it ensures
0:0:50: the continuation of a
0:0:53: species now you may say that newborns
0:0:55: are not the same as their
0:0:57: parents well it is not the same organism
0:1:1: but the same
0:1:2: species an apple tree gives rise to an
0:1:5: apple
0:1:6: tree similarly a dog gives rise to a
0:1:10: puppy so this is what we mean by
0:1:12: reproduction that is producing the same
0:1:15: species every time to ensure the
0:1:17: sustainance of the particular
0:1:20: species now the next question that pops
0:1:23: up in our mind is do all organisms
0:1:26: reproduce in the same
0:1:28: manner will a honey be and a lion
0:1:31: reproduce the same way absolutely not if
0:1:35: our mother earth is home to different
0:1:37: types of organisms with several
0:1:39: differences in their body structures
0:1:41: then how can the patterns of
0:1:43: reproduction be the
0:1:45: same this brings us to the two main
0:1:47: modes of reproduction in our Animal
0:1:50: Kingdom aexual reproduction and sexual
0:1:54: reproduction aexual reproduction is a
0:1:57: mode of reproduction in which a new
0:1:59: offspring is produced by a single parent
0:2:2: the new individuals produced are
0:2:4: genetically and physically identical to
0:2:6: each other sexual reproduction is a
0:2:10: natural way of reproduction that
0:2:12: involves the fusion of male and female
0:2:14: gametes known as
0:2:16: fertilization it is usually slow and
0:2:19: complex in this video we will talk about
0:2:23: sexual
0:2:24: reproduction sexual reproduction is the
0:2:26: most common among mammals in the domain
0:2:30: of animals males and females have
0:2:32: distinct reproductive
0:2:34: organs these reproductive organs produce
0:2:37: tiny gametes which are specialized
0:2:39: reproductive cells involved in sexual
0:2:42: reproduction so the new individual
0:2:45: inherits some characteristics from the
0:2:47: mother and some from the
0:2:49: father let us examine the male
0:2:51: reproductive system the male
0:2:54: reproductive system comprises of a set
0:2:56: of testes two sperm ducts and a penis
0:3:0: the testes are responsible for
0:3:2: generating male gametes known as sperm
0:3:5: millions of sperms are generated by the
0:3:8: testes sperms are small and have three
0:3:11: distinct Parts head middle piece and
0:3:14: tail despite their size each sperm is a
0:3:18: single cell with typical cell
0:3:20: components now let's study the female
0:3:23: reproductive
0:3:24: organs the female reproductive system
0:3:27: comprises of ovaries ucts or Fallopian
0:3:30: tubes and the
0:3:32: uterus ovaries actively produce female
0:3:35: gametes known as OVA or eggs once a
0:3:38: month a matured egg gracefully makes its
0:3:41: way into the
0:3:43: UCT the uterus a nurturing Harbor holds
0:3:46: and protects the developing baby similar
0:3:50: to the sperm and ex stands as a
0:3:52: remarkable single cell do you know what
0:3:54: is the first step that is involved in
0:3:58: reproduction
0:4:0: yes you guessed it
0:4:1: right it is
0:4:5: fertilization in most organisms gametes
0:4:8: are of two different types sperm which
0:4:11: is male gamet and egg which is female
0:4:15: gamet when the male and female gametes
0:4:17: are united they give rise to zygote
0:4:20: which is an initial cell formed during
0:4:22: the process of
0:4:23: fertilization the formation of the
0:4:25: zygote is a crucial stage in the early
0:4:28: development of an organism
0:4:30: all of us started the Journey of Our
0:4:32: Lives from this cell the process of
0:4:35: fusion combines the traits or the
0:4:37: characteristics of both
0:4:39: parents through a series of cell
0:4:41: divisions and differentiation the zygote
0:4:44: undergoes development eventually forming
0:4:47: a multicellular
0:4:50: organism let us summarize our learning
0:4:53: reproduction is the biological process
0:4:56: of creating new members of a species
0:4:58: from one parent or
0:5:0: parents there are two modes of
0:5:2: reproduction sexual and
0:5:4: asexual sexual reproduction involves the
0:5:7: fusion of male and female gametes to
0:5:10: form a zygote which develops into a new
0:5:13: individual male reproductive organs
0:5:16: include testes sperm ducts and a penis
0:5:19: testes produce male gamuts called sperms
0:5:22: sperms have distinct Parts head middle
0:5:25: piece and tail female reproductive organ
0:5:29: include ovaries ucts Fallopian tubes and
0:5:33: the
0:5:33: uterus ovaries produce female gametes
0:5:36: called OV or eggs one matched egg is
0:5:39: released into the UCT each month the
0:5:43: uterus is where the development of the
0:5:45: baby takes place both sperm and egg are
0:5:48: single cells disp we hope that you have
0:5:51: understood the concept of reproduction
0:5:53: system now here's a secret on how you
0:5:56: can study effectively with the urap
0:6:0: you can learn with chapter notes watch
0:6:2: video lectures and solve ncer based McQ
0:6:6: tests of this chapter on
0:6:8: eduv and that's not all you also get
0:6:11: amazing courses for Class 8 and much
0:6:13: more for your class 8
0:6:15: preparation thank you
