Hello everyone, we continue with the cell, remember that the day we did the levels of organization 00:00:11
now we are going to focus on one of these levels, the cell, cell level 00:00:18
ok, so what do we have to do? 00:00:23
first of all, we have another point, so we write the heading 00:00:27
number 2, the cell, so that's the unit of life 00:00:31
Why do we say that is the unit of life? Think a little bit. Yes, because it's the first level 00:00:41
in which we can consider that it has life on its own. We cannot say that an organelle, for example, 00:00:49
has life. No, because it cannot survive without the whole cell. Okay, so what we need to do is, 00:00:55
I don't know if you can see it well. Okay, we're gonna prepare a cell like the one I have drawn 00:01:03
here on the board you look for a picture on internet copy it yeah you can trace it if you 00:01:09
want put the paper on the screen of your computer okay and we're going to make it in a small piece 00:01:17
of paper a paper that we can lift up and down so here we have to be all the different organelles 00:01:24
okay and underneath we're going to write the definition of cell and remember here we need 00:01:33
to write cell like the one i have here now i'm going to tell you the definition of cell 00:01:39
get ready to copy the cell is the most basic part of a living organism that is capable 00:01:45
of performing the three vital functions to that nutrition, coma, interaction and reproduction. 00:01:55
When we're finished with drawing ourselves and writing the definition, we're going to 00:02:06
make a couple of exercises. 00:02:12
Remember that these exercises must be on the other part of our notebook. 00:02:14
It cannot be on the same part where we have the theory. 00:02:18
So get ready to copy the exercises. 00:02:22
Continuing with our notebook, on the same point of the cell, we're going to write characteristics of human cells. 00:02:36
Let's see what characteristics do we have. 00:02:46
First of all, human cells are heterotrophic, and second, they are eukaryotic. 00:02:48
To write the definition of heterotrophic and eukaryotic, we're going to cut two triangles, okay? 00:02:54
And we're going to make a flap because we need to write the definition underneath. 00:03:01
Okay, you see? 00:03:07
Okay, and mark the triangle. 00:03:08
So, let's see. 00:03:10
Let's start with aterotrophic. 00:03:11
Aterotrophic is a cell that obtains nutrients from other organisms. 00:03:13
And eukaryotic is a cell with nucleus and organelles surrounded by membranes. 00:03:19
and so prepare these two flaps now now you're gonna watch a video and keep an 00:03:27
eye on it and we're gonna talk about the different parts of the cell 00:03:54
now you're gonna watch a video and keep an eye on it and we're gonna talk about 00:04:03
the different parts of the cell let's see the basic parts of ourselves so first of all we have 00:04:11
something that surrounds the cell that is the wall that doesn't allow all the substances to 00:04:32
get inside the cell do you remember the name of it it was membrane yes it was the membrane 00:04:40
As I said, it's the point where the substances would be allowed to get inside the cell 00:04:52
or won't be allowed to get inside the cell. 00:04:57
Then, when you get in, there was a liquid substance that was called in the red, 00:05:00
that it was called cytoplasm. 00:05:06
Inside this liquid, we have different things floating on top. 00:05:16
What were the name of them? 00:05:24
They were the organelles 00:05:25
Also inside the cytoplasm 00:05:27
There is the central part of the cell 00:05:35
That organises the rest 00:05:38
What was the name of it? 00:05:39
The nucleus 00:05:42
So we have four parts 00:05:43
We have membrane, cytoplasm, organelles and nucleus 00:05:50
