in this video I'm going to explain you the classification of living things first I'm
00:00:01
going to start with the term of a species we can see that a species is a set of living things with
00:00:17
similar characteristics that can breed among themselves and have fertile offspring the
00:00:25
variety of living things in one place is called biodiversity or biological
00:00:35
diversity. Some species have been identified so far. Each species is
00:00:42
adapted to live in a specific environment. Classification of living
00:00:49
things. Here you have a chart of the classification of living things. You only
00:00:55
need to have a look because we are going to study the kingdoms now. In these two columns
00:01:01
we find Monera with bacteria and in the rest of the columns in an orange color we can distinguish
00:01:10
between protists, fungi, plants and animals. Nomenclature of species. The names usually used
00:01:19
to refer to species, are their common names. The problem is that these often
00:01:30
vary from one region to another. For that reason, it was necessary to establish a single
00:01:36
international name for each species, referred to as the scientific name.
00:01:43
The scientific names are given according to a binomial nomenclature proposed by Linnaeus in 1758.
00:01:51
This is the first word, the genus, and it's written with the first letter in uppercase.
00:02:03
And this is the second word, the species. It's written in lowercase.
00:02:13
Here we have an example. You know what is this flower. The example is poppy. The genus would be
00:02:22
papaver species roeas and the scientific name is papaver roeas.
00:02:31
It's obvious you don't need to know all these scientific names. Nearly 400 years before
00:02:40
the birth of Christ, Aristotle classified living things into two major groups
00:02:49
of kingdoms, the animal kingdom and the plant kingdom. However, today we know of many organisms
00:02:54
that cannot be considered animals or plants and three new kingdoms have been created for them
00:03:01
fungi protoctists and monera now we are going to explain them monera kingdom this kingdom includes
00:03:08
those microscopic organisms formed by a single prokaryotic cell without nucleus they are
00:03:21
bacterias. Prototyx kingdom. Some organisms ingest food but they only have one cell.
00:03:29
Fungi kingdom. This kingdom feed on organic matter. It includes molds, fungi, mushrooms, and yeasts.
00:03:41
Plant kingdom. This kingdom includes trees, shrubs, and herbs. They can absorb inorganic
00:03:54
substances through the roots and synthesize nutrients in their leaves through photosynthesis
00:04:01
using the green pigment called clarophyll.
00:04:06
And finally animal kingdom.
00:04:11
They are living things that feed on other living things.
00:04:12
We will study plants and animals in next units.
