1 00:00:08,179 --> 00:00:14,179 Hello, let's continue with the classification of the plants. 2 00:00:14,179 --> 00:00:20,760 We are on our notebooks, we need to write 1.2 classification and add this heading to 3 00:00:20,760 --> 00:00:23,859 the table of contents, remember. 4 00:00:23,859 --> 00:00:26,859 Let's see the different types of plants that we can have. 5 00:00:26,859 --> 00:00:32,259 Okay, we are going to make a classification depending on whether they have flowers or 6 00:00:32,259 --> 00:00:33,259 not. 7 00:00:33,259 --> 00:00:39,920 non-flowering plants and flowering plants. Which one are the non-flowering plants? 8 00:00:39,920 --> 00:00:44,759 In all the flowering plants, meaning that they do not have flowers, they have the 9 00:00:44,759 --> 00:00:53,899 bryophytes. Bryophytes are the mosses. I'll put some pictures here. Mosses are small 10 00:00:53,899 --> 00:01:00,979 plants, maybe you have used it to prepare in Christmas the portal de Belén, okay, 11 00:01:00,979 --> 00:01:09,019 just to cover the that part okay and they are very small and they do not have flowers 12 00:01:09,019 --> 00:01:15,140 we have also the pteridophytes which are the ferns in Spanish we call them 13 00:01:15,140 --> 00:01:23,239 helechos they are very common in areas that are humid let's go to the flowers 14 00:01:23,239 --> 00:01:30,799 okay in the flowering plants we have two types we have the gymnosperms that here 15 00:01:30,799 --> 00:01:39,319 we include trees like the pine, like the cypress, pinos depreses, 16 00:01:39,319 --> 00:01:47,540 arithonicas, all those are gymnosperms. And the angiosperms are those ones that 17 00:01:47,540 --> 00:01:56,180 have real fruits. And here we have the rest, poppies, cherry tree, apple tree, 18 00:01:56,180 --> 00:02:02,260 oaks, any other type of tree that are not in the gymnosperms, we find it in the angiosperms 19 00:02:02,260 --> 00:02:05,780 and also small plants are angiosperms 20 00:02:13,460 --> 00:02:20,819 We start with the next sections, from the classification we take the non-flowering plants 21 00:02:20,819 --> 00:02:26,819 Point two, non-flammable implants, table of contents, 2.1, bryophytes. 22 00:02:26,819 --> 00:02:30,819 Bryophytes are the mosses, musgos. 23 00:02:30,819 --> 00:02:34,819 What are the parts of these mosses, of these bryophytes? 24 00:02:34,819 --> 00:02:43,819 Okay, they have something similar to roots, but they are not roots, which are called the rhizoids. 25 00:02:43,819 --> 00:02:49,819 They have something similar to the stem, but it's not the stem, which is the caglidium. 26 00:02:49,819 --> 00:02:56,699 And they have something similar to the leaves, but they are not leaves, which are the phyllidia. 27 00:02:56,699 --> 00:02:59,740 Okay? So, Rhythoid, Scallidium, Phyllidia. 28 00:02:59,740 --> 00:03:03,300 And, but, that is not the most important part of the mosses. 29 00:03:03,300 --> 00:03:09,300 The most important part is that they are divided into two different organisms. 30 00:03:09,300 --> 00:03:11,840 The gametophyte and the sporophyte. 31 00:03:11,840 --> 00:03:16,879 The gametophyte, we find it most of the time with the mosses we see the gametophyte. 32 00:03:16,879 --> 00:03:23,960 The sporophyte is a structure growing on the gametophyte that helps with reproduction 33 00:03:23,960 --> 00:03:28,039 So sporophyte only for reproduction 34 00:03:28,039 --> 00:03:36,879 And this part of the sporophyte is called the sporangium and when it opens it releases spores 35 00:03:36,879 --> 00:03:40,039 So I repeat, gametophyte and sporophyte 36 00:03:40,039 --> 00:03:46,400 Sporophyte only with reproduction and when it opens it releases spores 37 00:03:46,400 --> 00:03:50,639 some important facts about the baryophytes that you need to know 38 00:03:50,639 --> 00:03:54,719 first of all they do not have conducting vessels 39 00:03:54,719 --> 00:04:01,039 conducting vessel transport the sap up and down the plant but baryophytes 40 00:04:01,039 --> 00:04:05,199 do not have conducting vessels 41 00:04:06,240 --> 00:04:10,800 they need water and shade because another plant 42 00:04:10,800 --> 00:04:15,360 can grow because the conducting vessels hit the water from the roots to the 43 00:04:15,360 --> 00:04:20,639 leaves but mosses do not have so they need water and shade and usually they are small 44 00:04:21,439 --> 00:04:29,920 and these mosses help to prevent erosion of soil that is very important in nature because these 45 00:04:29,920 --> 00:04:34,079 Mouses are some of the first organism to colonize an empty space
