Quick Revision: Reproduction in Animals Video Lecture | Science for Grade 4

0:0:0: hey
0:0:1: everyone Welcome to our journey through
0:0:3: the fascinating world of
0:0:5: animals today we are diving into a super
0:0:8: cool topic how animals create more
0:0:11: animals just like themselves this
0:0:14: process is called
0:0:16: reproduction in other words all living
0:0:18: things have the ability to produce more
0:0:20: of their own kinds the process by which
0:0:24: living things produce young ones of
0:0:25: their own kinds is called
0:0:28: reproduction reproduction is important
0:0:30: for the continuity of life on the earth
0:0:33: thanks to reproduction the Earth is
0:0:35: teaming with life ensuring that animals
0:0:38: continue to exist generation after
0:0:41: generation in the animal kingdom
0:0:43: creatures have two main ways to
0:0:45: reproduce and bring their young ones
0:0:47: into the world some animals lay eggs
0:0:51: while others give birth to their
0:0:53: babies each method is unique and
0:0:56: perfectly suited to the animals lives
0:0:59: let's find out more about these
0:1:1: incredible
0:1:2: processes first up let's talk about
0:1:5: animals that lay eggs this group
0:1:8: includes many that you might already
0:1:10: know like birds frogs and even
0:1:13: mosquitoes these animals lay eggs and
0:1:16: the baby develops inside the egg it
0:1:20: needs warm conditions for
0:1:22: development so parent animals either
0:1:25: keep eggs in a warm place or they sit on
0:1:27: eggs to keep them warm after after some
0:1:30: time the baby hatches out of the egg let
0:1:33: us discuss about eggs in
0:1:36: detail an egg has a thin hard outer
0:1:39: shell called eggshell eggshell protects
0:1:42: the baby inside it a white jelly-like
0:1:45: substance called albumin is present
0:1:48: inside the egg albumin is rich in
0:1:51: proteins within the albumin is a yellow
0:1:54: part called the Yoke birds make sure
0:1:57: their eggs are safe and sound until it's
0:1:59: time for the little ones to hatch let's
0:2:2: zoom in on a familiar feathered friend
0:2:5: the chicken chickens start their life as
0:2:8: an egg inside this egg a tiny embryo
0:2:11: develops into a chick after some time
0:2:15: the egg hatches and out comes a chicken
0:2:18: it's a simple yet Miraculous Journey
0:2:20: from an egg to a full-grown chicken now
0:2:23: moving on to the smallest of egg layers
0:2:26: insects did you know all insects start
0:2:29: their life has an egg take butterflies
0:2:32: for example a butterfly lays its eggs on
0:2:36: leaves then each egg hatches into a
0:2:39: caterpillar also known as a
0:2:41: larva this is just the beginning of a
0:2:44: process called metamorphosis where the
0:2:46: caterpillar transforms into a beautiful
0:2:49: adult
0:2:50: butterfly it's like magic apart from
0:2:53: birds and insects many other animals lay
0:2:56: eggs this includes reptiles like Snak
0:3:0: and lizards amphibians like frogs and
0:3:2: even fish each of these creatures
0:3:5: ensures their eggs are kept warm and
0:3:7: safe until it's time for their babies to
0:3:10: hatch now let's meet the animals that
0:3:13: give birth to their
0:3:15: babies this group is called
0:3:18: mammals mammals like cows dogs and even
0:3:21: humans have their babies develop inside
0:3:24: the mother's body once born the babies
0:3:27: drink their mother's milk
0:3:30: mammals including those living in the
0:3:32: sea like whales and dolphins take great
0:3:35: care of their babies protecting them and
0:3:37: finding food for them it's all about
0:3:41: family love in the mammal World mammals
0:3:44: have a unique bond with their
0:3:46: babies the baby grows inside the
0:3:49: mother's body for several weeks after
0:3:52: birth the mother feeds her baby with her
0:3:54: milk and takes very good care of it
0:3:58: mammals also protect their baby bees
0:4:0: from
0:4:0: enemies they also hunt for food to wrap
0:4:4: up let's take a closer look at a few
0:4:7: remarkable mammals Bears Dolphins
0:4:11: rhinoceroses and kangaroos are just a
0:4:13: few examples of animals that give birth
0:4:16: to live
0:4:17: babies each of these mammals has its own
0:4:20: unique way of caring for and nurturing
0:4:22: its young and there you have it from
0:4:26: eggs to babies the world of animal
0:4:28: reproduction is full of of
0:4:30: Wonders we hope that you have understood
0:4:33: the topic you can now study chapter
0:4:36: notes watch video lectures and solve McQ
0:4:39: tests of this chapter on uff to ensure
0:4:42: you score well in your school
0:4:44: exams and that's not all you also get
0:4:47: amazing courses for maths science
0:4:49: English Hindi and much more for class 4
0:4:53: thank you
