TERMOS DE CLASSIFICAÇÃO DOS SERES VIVOS | Resumo de Biologia para o Enem

📚 Free e-book with the most common terms in Mathematics and Natural Sciences in the Enem exam: http://bit.ly/35OYaeg Biology is famous for using several names that students consider very difficult. Aerobic, anaerobic, prokaryotes, eukaryotes... all of these are terms that tend to be strange to those who are not used to scientific language. Do you want to master all the terms used in the classification of living beings? Come and let Professor Ju help you \o/ Learn about our free course: https://goo.gl/2rebsa Written class on this content: https://goo.gl/4wPd5t Simulation of this content: https://goo.gl/86bB5E Video description: 00:00 to 00:29 - Introduction by the teacher and opening vignette. 00:30 to 1:03 - Today we're going to talk about terms that are used to classify living beings according to cell type, number of cells, type of metabolism and type of respiration. This is very important so that we can group living beings with common characteristics and classify them within taxonomic categories (kingdom, phylum, order, etc.). It seems a bit difficult because they are weird names, but if you pay attention you'll notice that the words themselves tell you what they mean. Let's go! \o/ 1:04 to 2:05 - Unicellular vs. Multicellular: Unicellular beings are living beings that have a single cell, as is the case with bacteria, protozoa and some fungi. Multicellular beings are composed of many cells that can differentiate into tissues or not. Algae are multicellular, but they don't have much tissue differentiation, unlike animals, which have several cells organized into different tissues. 2:06 to 3:24 - Autotrophs X Heterotrophs: Autotrophic beings produce their own food through metabolic processes that their cells perform. There are several types of autotrophic nutrition and photosynthesis is one of them. Heterotrophic beings depend on other living beings to feed themselves, because they do not have cellular structures capable of producing their own food. These living beings absorb or ingest nutrients from the environment. We, human beings, are heterotrophs. 3:25 to 4:56 - Prokaryotes X Eukaryotes: The only prokaryotic living beings are those of the Monera kingdom (bacteria and cyanobacteria). This type of cell is the simplest that exists among beings. It does not have membranous organelles inside it, that is, everything happens somewhat mixed up in the cytoplasm, because there are no separate compartments inside it. These cells do not have a nucleus, that is, there is no nuclear envelope to enclose the genetic material and separate it from the rest of the cell content. Eukaryotic organisms are those that have more complex cells, with membranous organelles. Eukaryotes are all living beings except bacteria. 4:57 to 7:07 - Aerobes vs. Anaerobes: Cellular respiration is a process that serves to break down nutrients and release the energy contained in them. Aerobes are those that, like us, use oxygen to do this breakdown. Anaerobic organisms are those that do not use oxygen during respiration and carry out other types of processes to break down nutrients, such as fermentation. Within this category, there are two groups: obligate anaerobes (those that die in the presence of oxygen, such as the tetanus bacteria, for example) and facultative anaerobes (those that perform aerobic respiration when oxygen is present and, in its absence, carry out another process... yeast in bread is an example). 7:08 to 7:31 - End of the class.
