Guetta friends Welcome to the
0:05
second babsel material school zone in this material we
0:08
will discuss the history of cells where in the
0:11
previous video we already know
0:13
What is the definition of cells Okay Let's go straight to
0:18
this nashob is a picture of
0:25
Hi talking about microscopes this tool was
0:28
very viral among researchers
0:30
in the 1600s because at that time it
0:33
was the beginning of the discovery of microscopes
0:36
and at that time it was a new thing
0:38
for researchers to see
0:40
very small objects until finally
0:43
scientists for the first time discovered
0:45
cells Okay we will sort the history of
0:47
the discovery of soft cells we already know
0:50
yes Cells are the smallest structural and
0:52
functional units of living things well the
0:56
history of the discovery of cells occurred over
0:57
several periods and the discovery also
1:00
involved several scientists in each
1:04
Hi the discovery of cells began in
1:08
1591 at that time there was a
1:11
glasses maker named zacharias Janssen
1:14
he made a tool that functioned like a
1:16
magnifying glass from a tube at both
1:19
ends he placed a lens more or
1:22
less the tool Like this shop at that time
1:24
he used this tool to see
1:26
objects that are very small and
1:28
cannot be seen directly by our eyes
1:30
where this tool is what we now know
1:33
as a microscope Oh yes it is necessary It is known
1:36
that the image produced by the
1:38
microscope made by Zacharias Janssen
1:41
is still blurry or not very
1:44
clear because at that time the microscope
1:47
did not have a feature to adjust the
1:49
focus shop well since then
1:52
until the end of the early 1600s
1:55
this microscope went viral among researchers
2:02
own microscopes so they could see objects
2:05
that were very small in size
2:09
1665 there was a researcher from
2:12
England named Robert Hooke He really
2:15
liked to see and examine
2:17
small objects using his microscope until
2:20
One day he conducted an experiment
2:22
looking at the lines of dead plant stems
2:24
which were precisely the
2:28
from his observations he saw
2:30
small empty boxes Where
2:35
cork tissue out well when he saw that He
2:38
thought that it was similar to Sheila
2:41
it was a place for monks to pray
2:43
and also rest Well because what was
2:45
observed was similar to Sheila then he
2:48
gave the name What he saw was the
2:50
name of the cell well This is what
2:53
made Robert Hooke the
2:55
first person to coin the name cell Oh yes
2:58
Sob This product not only observes
3:01
cork tissue but he also
3:03
observes many objects such as insects
3:06
moss and Hi then the results of his observations
3:10
he collected in a book
3:12
entitled micrographia well this book
3:17
1665 so in this year it was made the
3:20
year where the word cell was first
3:24
Okay now we move on to 1674
3:28
Anthony Van leuwenhook Well yes also
3:32
really likes to see small objects
3:33
using a microscope but here he
3:36
did his research using a
3:38
microscope that he made himself for his
3:41
microscope model like this shop well with his
3:43
microscope capital antonini
3:46
tried to observe several samples
3:48
such as flowers insects rainwater and
3:51
others well when observing many
3:54
samples Earlier he saw small creatures
3:58
small animals so he named them
4:01
animal Crush Hai which means
4:06
Hai Well with this he was the
4:08
first person to see life
4:10
using a microscope Then after
4:12
the discovery of this life sale microscopes are
4:15
increasingly developing shop the development of
4:17
microscopes is also followed by the
4:19
development of cell discoveries so in
4:23
1838 there were two German biology researchers
4:26
who discovered new things about
4:28
their cells are Mathias Jacob
4:31
schleiden and also tedder swans
4:34
Hi at that time Jacob I and that researched
4:37
plant tissue using a microscope
4:44
made a conclusion that all
4:47
plants are composed of cells well in
4:50
other places careless also conducted research
4:53
on animal tissue under a microscope
4:55
then in the same year he also
4:57
concluded that all animals are composed
5:00
of cells finally they met each other
5:04
and agreed that all living things are
5:06
composed of cells so that cells
5:09
are the basic units of life
5:11
shop Well after that researchers began
5:16
where the cells actually came from
5:21
1858 a German researcher named
5:25
Rudolf Virchow discovered the fact that cells
5:28
can divide the fact was discovered
5:31
after he studied or researched the
5:33
reproduction of cells Hi well the results of
5:36
his research were published in a book
5:38
entitled cellular pathology and
5:41
in the book he said that cells
5:44
come from other cells
5:47
Hi nashob from the history of the discovery of this cell
5:49
three theories about cells were born that
5:54
Hi the first is that all
5:56
living things are composed of cells Then the second
6:00
cell is the smallest structural and
6:02
functional unit of living things
6:04
and the third says that cells
6:08
come from other cells through
6:10
cell division Well so that's the history
6:13
of cells Hopefully it can be digested function
6:15
and live for all ordinary friends don't
6:18
forget to watch and study the
6:19
next material and other learning videos
6:21
so See you next video sold
