Com a tema de medi natural, hem estudiat la c\u00e8l\u00b7lula.<\/p>\n
La c\u00e8l\u00b7lula \u00e9s la unitat m\u00ednima que t\u00e9 vida pr\u00f2pia. \u00c9s capa\u00e7 de nodrir-se, relacionar-se i reproduir-se.<\/p>\n
Hi ha \u00e9ssers vius que nom\u00e9s tenen una c\u00e8l\u00b7lula, com les bact\u00e8ries, per\u00f2 altres s\u00f3n pluricel\u00b7lulars. Les c\u00e8l\u00b7lules s’agrupen formant teixits, \u00f2rgans i aparells (fetge, rinyons, sistema nervi\u00f3s…) i formen individus m\u00e9s complexos, com les plantes i els animals.<\/p>\n
En una c\u00e8l\u00b7lula podem observar dues parts: la membrana cel\u00b7lular i el citoplasma. El citoplasma \u00e9s la part interna de la c\u00e8l\u00b7lula i cont\u00e9 diversos org\u00e0nuls (aparell de Golgi, ribosomes, mitocondris, reticle endoplasm\u00e0tic…). Per\u00f2 la part m\u00e9s interssant \u00e9s que hi ha un nucli\u00a0 (\u00e9s l’\u00f2rgan encarregat de dirigir les funcions de la c\u00e8l\u00b7lula: captar aliment, coordinar els moviments i reproduir-se). Algunes c\u00e8l\u00b7lules no tenen un nucli per protegir els cromosomes (les bact\u00e8ries).<\/p>\n
Per aprendre b\u00e9 aquestes parts, per grups vam construir una maqueta de la c\u00e8l\u00b7lula, amb diferents org\u00e0nuls i la vam exposar a classe.<\/p>\n\n
La majoria de les c\u00e8l\u00b7lules s\u00f3n molt petites i nom\u00e9s es poden observar amb un microscopi.\u00a0A classe vam\u00a0 observar diverses classes de c\u00e8l\u00b7lules amb el microscopi: gl\u00f2buls vermells, c\u00e8l\u00b7lules de pi… i tamb\u00e9 vam observar petits organismes unicel\u00b7lulars que hi havia en una gota d’aigua d’un bassal del pati.<\/p>\n","protected":false},"excerpt":{"rendered":"
