0 00:00:00,000 --> 00:00:10,000 Imagine, we take a tour inside your body. 1 00:00:10,000 --> 00:00:16,000 Where do you think we'll land up if we reach one of the farthest points? 2 00:00:16,000 --> 00:00:18,000 You guessed it right! 3 00:00:18,000 --> 00:00:22,000 Today, we are going to talk about the cell. 4 00:00:22,000 --> 00:00:25,000 Come on now, zoom in! 5 00:00:26,000 --> 00:00:30,000 So, I am inside the human body right now. 6 00:00:30,000 --> 00:00:34,000 But I need to go deeper inside to find the cell. 7 00:00:34,000 --> 00:00:42,000 I am passing through the organs, the tissues and I think I am almost there. 8 00:00:42,000 --> 00:00:45,000 Yes! Here I am! 9 00:00:45,000 --> 00:00:48,000 This is the cell. 10 00:00:49,000 --> 00:00:51,000 Well, always remember this. 11 00:00:51,000 --> 00:00:54,000 A cell is the basic unit of life. 12 00:00:54,000 --> 00:00:59,000 All living things started out from a single cell. 13 00:00:59,000 --> 00:01:02,000 You started out from right here, buddy! 14 00:01:02,000 --> 00:01:07,000 But the cell is made up of some components. 15 00:01:07,000 --> 00:01:14,000 A cell membrane is the outer covering of the cell, which is like your skin. 16 00:01:15,000 --> 00:01:21,000 It allows some substances to seep in and keeps the harmful ones at bay. 17 00:01:22,000 --> 00:01:26,000 Mitochondria, this is the powerhouse of the cell. 18 00:01:26,000 --> 00:01:30,000 As it provides for all the energy the cell needs. 19 00:01:30,000 --> 00:01:39,000 When the human body consumes food, the digested part of the food reacts with oxygen and mitochondria. 20 00:01:39,000 --> 00:01:42,000 To create energy for that cell. 21 00:01:42,000 --> 00:01:43,000 Boom! 22 00:01:44,000 --> 00:01:49,000 The ribosomes are very important as they make proteins. 23 00:01:49,000 --> 00:01:53,000 Which are used to repair any damage caused. 24 00:01:53,000 --> 00:01:55,000 Nucleus. 25 00:01:55,000 --> 00:01:58,000 Now, here comes the brain of the cell. 26 00:01:58,000 --> 00:02:05,000 If we go inside the nucleus, we'd find chromosomes which carry out the instructions of the br.. 27 00:02:06,000 --> 00:02:09,000 Aha! I mean the nucleus of the cell. 28 00:02:09,000 --> 00:02:12,000 Cytoplasm. 29 00:02:12,000 --> 00:02:17,000 This is the space where all the components of a cell take a chill pill. 30 00:02:17,000 --> 00:02:23,000 Well, what I mean is that the cytoplasm fills up the rest of the cell. 31 00:02:24,000 --> 00:02:27,000 Where the other components of the cell keep floating. 32 00:02:27,000 --> 00:02:30,000 As this is mostly water. 33 00:02:30,000 --> 00:02:32,000 Lysosomes. 34 00:02:32,000 --> 00:02:37,000 Like we all have trash cans, the cells have lysosomes. 35 00:02:37,000 --> 00:02:43,000 Which get rid of the waste material and other unwanted substances in the cell. 36 00:02:44,000 --> 00:02:46,000 Trivia Time! 37 00:02:46,000 --> 00:02:51,000 The cell was first discovered by a scientist named Robert Hooke. 38 00:02:51,000 --> 00:02:56,000 Humans carry more bacteria than human cells itself. 39 00:02:56,000 --> 00:02:58,000 Imagine that! 40 00:02:58,000 --> 00:03:03,000 So friends, while I prepare my journey out of this human body. 41 00:03:04,000 --> 00:03:08,000 You tell me, what is the powerhouse of the cell called? 42 00:03:08,000 --> 00:03:12,000 This is me going home. 43 00:03:12,000 --> 00:03:14,000 Going home! 44 00:03:14,000 --> 00:03:17,000 This is me Zooming out!
