1 00:00:01,199 --> 00:00:17,449 in this video I'm going to explain you the classification of living things first I'm 2 00:00:17,449 --> 00:00:25,309 going to start with the term of a species we can see that a species is a set of living things with 3 00:00:25,309 --> 00:00:35,049 similar characteristics that can breed among themselves and have fertile offspring the 4 00:00:35,049 --> 00:00:42,130 variety of living things in one place is called biodiversity or biological 5 00:00:42,130 --> 00:00:49,149 diversity. Some species have been identified so far. Each species is 6 00:00:49,149 --> 00:00:55,750 adapted to live in a specific environment. Classification of living 7 00:00:55,750 --> 00:01:01,369 things. Here you have a chart of the classification of living things. You only 8 00:01:01,369 --> 00:01:09,530 need to have a look because we are going to study the kingdoms now. In these two columns 9 00:01:10,409 --> 00:01:19,370 we find Monera with bacteria and in the rest of the columns in an orange color we can distinguish 10 00:01:19,370 --> 00:01:30,730 between protists, fungi, plants and animals. Nomenclature of species. The names usually used 11 00:01:30,730 --> 00:01:36,969 to refer to species, are their common names. The problem is that these often 12 00:01:36,969 --> 00:01:43,290 vary from one region to another. For that reason, it was necessary to establish a single 13 00:01:43,290 --> 00:01:49,849 international name for each species, referred to as the scientific name. 14 00:01:51,450 --> 00:01:59,930 The scientific names are given according to a binomial nomenclature proposed by Linnaeus in 1758. 15 00:02:03,200 --> 00:02:12,159 This is the first word, the genus, and it's written with the first letter in uppercase. 16 00:02:13,439 --> 00:02:21,080 And this is the second word, the species. It's written in lowercase. 17 00:02:22,520 --> 00:02:31,879 Here we have an example. You know what is this flower. The example is poppy. The genus would be 18 00:02:31,879 --> 00:02:39,159 papaver species roeas and the scientific name is papaver roeas. 19 00:02:40,599 --> 00:02:49,199 It's obvious you don't need to know all these scientific names. Nearly 400 years before 20 00:02:49,199 --> 00:02:54,240 the birth of Christ, Aristotle classified living things into two major groups 21 00:02:54,240 --> 00:03:01,919 of kingdoms, the animal kingdom and the plant kingdom. However, today we know of many organisms 22 00:03:01,919 --> 00:03:08,000 that cannot be considered animals or plants and three new kingdoms have been created for them 23 00:03:08,960 --> 00:03:21,819 fungi protoctists and monera now we are going to explain them monera kingdom this kingdom includes 24 00:03:21,819 --> 00:03:29,900 those microscopic organisms formed by a single prokaryotic cell without nucleus they are 25 00:03:29,900 --> 00:03:39,259 bacterias. Prototyx kingdom. Some organisms ingest food but they only have one cell. 26 00:03:41,610 --> 00:03:52,330 Fungi kingdom. This kingdom feed on organic matter. It includes molds, fungi, mushrooms, and yeasts. 27 00:03:54,569 --> 00:04:01,449 Plant kingdom. This kingdom includes trees, shrubs, and herbs. They can absorb inorganic 28 00:04:01,449 --> 00:04:06,569 substances through the roots and synthesize nutrients in their leaves through photosynthesis 29 00:04:06,569 --> 00:04:11,229 using the green pigment called clarophyll. 30 00:04:11,229 --> 00:04:12,770 And finally animal kingdom. 31 00:04:12,770 --> 00:04:16,430 They are living things that feed on other living things. 32 00:04:16,430 --> 00:04:19,129 We will study plants and animals in next units.
