Hi, everyone. In this video, we are going to practice lesson two in our natural science subject. 00:00:04
From a cell to an organism. Mirror word. From a cell to an organism. 00:00:21
What is a cell? 00:00:34
A cell is the smallest living unit. 00:00:44
We need a microscope to see individual cell, like a population of bacteria on a petri dish. 00:00:52
Mirror word. 00:01:14
What is a cell? 00:01:15
A cell is the smallest living unit. 00:01:18
We need a microscope to see individual cells, 00:01:29
like a population of bacteria on a petri dish. 00:01:42
One cell, many cells. 00:01:50
Unicellular organisms, multicellular organisms, unicellular organisms only have one cell. 00:02:03
Multicellular organisms have many cells. 00:02:33
The cell carries out three vital functions. 00:02:40
Different cells have a different function. 00:02:52
Algae and bacteria are unicellular organisms. 00:03:02
Plants and animals are multicellular organisms. 00:03:08
Mirror word. 00:03:20
One cell. 00:03:24
Many cells. 00:03:28
Unicellular organisms. 00:03:33
Multicellular organisms. 00:03:39
Unicellular organisms only have one cell. 00:03:43
Multicellular organisms have many cells. 00:03:58
The cell carries out three vital functions. 00:04:11
Different cells have different functions. 00:04:17
Fungi and bacteria are unicellular organisms. 00:04:29
Plants and animals are multicellular organisms. 00:04:38
Now, are cells organized? 00:04:49
Multicellular organisms have five levels of organization. 00:05:13
Level one, cells. 00:05:25
Level two, tissue. 00:05:30
Level three, organ. 00:05:35
Level four, systems. 00:05:38
Level five, living organisms. 00:05:43
Mirror word. 00:05:54
Level one. 00:05:56
No, our cells organized. 00:05:58
Multicellular organisms have five levels of organization. 00:06:05
Level one. 00:06:18
cells. Level two, tissue. Level three, organ. Level four, systems. Level five, living organism. 00:06:19
Level 1. Cells are the smallest living unit. 00:06:42
Level 2. Cells are grouped together to form tissue. 00:06:55
Level 3. Tissues are grouped together to form an organ. 00:07:05
Level 4. Organs work together and form systems. 00:07:12
Level 5. Systems form a living organism. 00:07:20
Mirror word. 00:07:30
Level 1. Cells are the smallest living unit. 00:07:34
Level 2. Cells group together to form tissue. 00:07:43
Level 3. Tissues group together and form an organ. 00:07:52
Level 4. Organs work together and form systems. 00:08:07
Level 5. Systems form a living organism. 00:08:16
Animal cells and plant cells. 00:08:27
Animal cell, plant cell. 00:08:48
Rectangular, oval, or irregular shape. 00:09:03
That's for animal. 00:09:08
Plant cell, regular shapes. 00:09:11
Mirror word. Animal cell. Plant cell. Animal cell. Rectangular. Oval. Or irregular shape. Plant cell. Regular shape. 00:09:15
animal cells and plant cells. 00:09:50
Number one, cell wall makes the plant rigid. 00:10:13
Number two, cell membrane controls substance 00:10:21
entering and leaving the cell. 00:10:34
Number three, vacuums, contain water. 00:10:38
Nucleus, controls cell functions. 00:10:52
Number five, chloroplast, contains chlorophyll. 00:11:02
Mirror word, cell wall, makes the plant rigid. 00:11:08
Cell membrane controls substance entering and leaving the cell. 00:11:23
Very sweet. 00:11:38
Vacuoles contain water. 00:11:42
Nucleus controls cell functions. 00:11:48
Number five. 00:11:57
Chloroplast. 00:11:59
contained chlorophyll. Okay, let's check the metaphors of the cell parts. So for 00:12:00
cell wall, it's the armor. The cell membrane is the door. The vacuole is the 00:12:25
water well the nucleus is the brain and the chloroplast is the solar panel 00:12:39
mirror word cell parts cell wall armor cell membrane door vacuum water well 00:12:51
nucleus, brain, chloroplast, solar, pet. 00:13:14
And that's our lessons about cell to organism. 00:13:26
I hope you enjoy practicing. See you! 00:13:31
