1
00:00:00,300 --> 00:00:10,279
Well, this is the final review for unit one cell. So we're gonna remember. Ready, steady go. So please, let me know.

2
00:00:11,179 --> 00:00:12,400
Marbella, what is a cell?

3
00:00:13,160 --> 00:00:27,600
A cell is a basic, basic unit of life. Remember, it's the simplest unit of life. Okay?

4
00:00:27,600 --> 00:00:30,399
Remember, we have living things and non-living things.

5
00:00:30,519 --> 00:00:35,100
In living things, it's the basic unit of life, okay?

6
00:00:35,359 --> 00:00:42,520
And cells form different types of living things, okay?

7
00:00:42,799 --> 00:00:47,340
So we have the processes, the main processes that we can find.

8
00:00:47,719 --> 00:00:52,200
There are the nutrition, when we have nutrients and energy, we have the food.

9
00:00:52,200 --> 00:01:01,119
remember there are some animals carnivores herbivores and omnivores do

10
00:01:01,119 --> 00:01:05,719
you remember that and they need to have all in our case we go to the

11
00:01:05,719 --> 00:01:10,819
supermarket or that kind of stuff right for plants they made their own food

12
00:01:10,819 --> 00:01:16,299
remember that okay it's that process the reproduction they have another

13
00:01:16,299 --> 00:01:28,120
individuals or another similar living things, okay? Interaction sensitivity is how we react to the

14
00:01:28,120 --> 00:01:34,540
environment, how we react to others, okay? To things that happen around us. Remember, we have different

15
00:01:34,540 --> 00:01:43,719
types of cells. We have animal cells or plant cells. Also, when we're talking about the cells like that,

16
00:01:43,719 --> 00:01:49,659
like basic units of life they can form animals and they can form plants and

17
00:01:49,659 --> 00:01:54,540
they are different and also we can call them unicellular and multicellular

18
00:01:54,540 --> 00:02:00,340
unicellular is when they are simple they are singles okay the one can be

19
00:02:00,340 --> 00:02:09,439
bacterias and yeast that we will use to prepare beer and bread

20
00:02:09,439 --> 00:02:12,460
multicellular. There are almost lots of cells.

21
00:02:13,300 --> 00:02:17,500
We can have animals, plants, and human beings. So, it could be

22
00:02:17,500 --> 00:02:21,240
like this. Okay? So, we can say, okay,

23
00:02:21,400 --> 00:02:25,099
multicellular, animals and plants. And we put this here. It doesn't matter.

24
00:02:25,759 --> 00:02:29,340
So, remember the main difference between

25
00:02:29,340 --> 00:02:33,419
animal cells and plant cells. The animal cells are flexible

26
00:02:33,419 --> 00:02:37,500
and they are smaller than the plant cells. And the plant cells,

27
00:02:37,500 --> 00:02:45,000
They have rigid cell walls, and they have chloroplasts, all right?

28
00:02:45,319 --> 00:02:47,219
They are bigger than the animal cells.

29
00:02:47,560 --> 00:02:52,139
Remember, the main parts of cells, there are membrane, organelles,

30
00:02:52,479 --> 00:02:53,759
cytoplans, and nucleus.

31
00:02:54,439 --> 00:02:59,759
But also the plants got cell walls and chloroplasts, okay?

32
00:03:00,199 --> 00:03:02,400
Just used to make the photosynthesis.

33
00:03:03,860 --> 00:03:04,460
All right?

34
00:03:04,460 --> 00:03:06,819
So this is what we are going to have in the exam.

35
00:03:07,500 --> 00:03:11,120
So, for example, they ask you, what is a cell?

36
00:03:11,340 --> 00:03:13,080
The cell is the basic unit of life.

37
00:03:13,419 --> 00:03:16,960
What are the main differences between cells, animal cells and plant cells?

38
00:03:17,680 --> 00:03:20,580
The animal cells are smaller than the plant cells.

39
00:03:20,780 --> 00:03:21,000
Okay?

40
00:03:21,860 --> 00:03:22,500
You understand?

41
00:03:23,280 --> 00:03:23,560
Yes.

42
00:03:24,460 --> 00:03:26,639
Even I can ask you to draw this.

43
00:03:26,819 --> 00:03:27,060
Okay?

44
00:03:27,060 --> 00:03:32,860
For example, this is a membrane.

45
00:03:33,879 --> 00:03:35,240
This is a membrane.

46
00:03:35,819 --> 00:03:36,680
This is the nucleus.

47
00:03:37,500 --> 00:03:41,259
the organelles and the citoplans. Remember.

48
00:03:41,259 --> 00:03:44,460
Vale, okay, we are. Thank you.

49
00:03:44,460 --> 00:03:47,500
Doubts? Do you have any doubts?

50
00:03:47,500 --> 00:03:50,500
Tell me. Tell me doubts.

51
00:04:03,810 --> 00:04:07,810
No. The citoplans, when they use tomato

52
00:04:07,810 --> 00:04:11,610
what they used to make the photosynthesis and the clonostauro

53
00:04:11,610 --> 00:04:16,610
but the chlorophyll is the sustance but it's green and they have it and they use it

54
00:04:16,610 --> 00:04:27,610
how do you search by the last 16 and 17?

55
00:04:27,610 --> 00:04:32,610
no pages 16 and 17 you have to just read it

56
00:04:32,610 --> 00:04:35,610
just to understand what you have to do

57
00:04:35,610 --> 00:04:36,689
Just read it, okay?

58
00:04:36,810 --> 00:04:37,790
This is going to be in the exam,

59
00:04:37,870 --> 00:04:39,850
because you know there's going to be a lot of things there.

60
00:04:40,350 --> 00:04:40,670
All right?

61
00:04:41,129 --> 00:04:43,689
So, more doubts?

62
00:04:44,029 --> 00:04:44,509
Doubts?

63
00:04:44,810 --> 00:04:45,490
Not tomorrow.

64
00:04:46,029 --> 00:04:46,250
No?

65
00:04:46,670 --> 00:04:47,949
Okay, tomorrow we'll see.

66
00:04:48,209 --> 00:04:48,529
Thank you.
