Resumo: | Cell theory condenses studies on the origin, composition and functioning of cells. The first contributors to this theory were Matthias Schleiden and Theodor Schwann who, through their studies, concluded that all living beings are made up of cells. The understanding of basic concepts of cell biology is fundamental for the learning of physiology, reproduction, heredity, propagation of diseases and interactions between living beings. Therefore, from elementary school to high school, science subjects cover cytology topics. However, these are treated in a predominantly theoretical way. Practical classes are extremely important for scientific literacy and should be carried out from basic education onwards. However, there is a lack of experiments that allow the visualization of animal cells in living tissue. In view of this, this article proposes a practical class using the worm Panagrellus redivivus in order to elucidate multicellularity as well as the formation of new cells and the living being through embryogenesis. This nematode is easy to obtain and handling is done using low-cost materials, but the learning gain is very high. It is believed that the use of this experimental model not only facilitates the understanding of the proposed topic but also helps and encourages the scientific training of students. |

Los primeros contribuyentes a esta teoría fueron Matthias Schleiden y Theodor Schwann quienes, a través de sus estudios, concluyeron que todos los seres vivos están formados por células. La comprensión de conceptos básicos de biología celular es fundamental para el aprendizaje de la fisiología, la reproducción, la herencia, la propagación de enfermedades y las interacciones entre los seres vivos. Por lo tanto, desde la escuela primaria hasta la secundaria, las materias de ciencias cubren temas de citología. Sin embargo, estos son tratados de una manera predominantemente teórica. Las clases prácticas son de suma importancia para la alfabetización científica y deben llevarse a cabo desde la educación básica en adelante. Sin embargo, faltan experimentos que permitan la visualización de células animales en tejido vivo. Ante esto, este artículo propone una clase práctica utilizando el gusano Panagrellus redivivus con el fin de dilucidar la pluricelularidad así como la formación de nuevas células y del ser vivo a través de la embriogénesis. Este nematodo es fácil de obtener y su manejo se realiza con materiales de bajo costo, pero la ganancia de aprendizaje es muy alta. Se cree que el uso de este modelo experimental no solo facilita la comprensión del tema propuesto sino que también ayuda y fomenta la formación científica de los estudiantes.A teoria celular condensa estudos sobre origem, composição e funcionamento das células. Os primeiros contribuintes dessa teoria foram Matthias Schleiden e Theodor Schwann que, por meio de seus estudos, concluíram que todos os seres vivos são formados por células. A compreensão de conceitos básicos de biologia celular é fundamental para o aprendizado da fisiologia, reprodução, hereditariedade, propagação de doenças e interações entre os seres vivos. Por isso, do ensino fundamental ao ensino médio, as disciplinas de ciências abordam tópicos de citologia. Todavia, esses são tratados de forma predominantemente teórica. Aulas práticas são extremamente importantes para a alfabetização científica e devem ser realizadas desde o ensino básico. Contudo, há uma carência de experimentos que permitam a visualização de células animais em tecidos vivos. Frente a isso, esse artigo propõe uma aula prática, utilizando o verme Panagrellus redivivus, com o objetivo de elucidar a multicelularidade, bem como a formação de novas células e do ser vivo por meio da embriogênese. Esse nematoide é de fácil obtenção e o manuseio é feito utilizando materiais de baixo custo, mas o ganho em aprendizagem é muito alto. Acredita-se que a utilização desse modelo experimental não só facilite o entendimento do tópico proposto, como também auxilie e incentive a formação científica dos discentes.Research, Society and Development2022-01-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2562910.33448/rsd-v11i2.25629Research, Society and Development; Vol. 11 No. 2; e29311225629Research, Society and Development; Vol. 11 Núm. 2; e29311225629Research, Society and Development; v. 11 n. 2; e293112256292525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/25629/22562Copyright (c) 2022 Larissa Stefanello ; Elgion Lucio da Silva Loretohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessStefanello , LarissaLoreto, Elgion Lucio da Silva 2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/25629Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:52.258995Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
