Fa unes setmanes, els i les alumnes de cicle superior<\/strong> hem fet un experiment molt interessant per aprendre com s\u00f3n les c\u00e8l\u00b7lules<\/strong>, que s\u00f3n les parts m\u00e9s petites dels \u00e9ssers vius.<\/p>\n\n\n\n

Tot el que ens envolta \u2014animals, plantes i persones\u2014 est\u00e0 format per c\u00e8l\u00b7lules. S\u00f3n tan petites que no es poden veure a simple vista, i per aix\u00f2 hem necessitat un microscopi<\/strong> per observar-les de prop.<\/p>\n\n\n\n

Per fer-ho, hem utilitzat una ceba<\/strong>, perqu\u00e8 la seva pell interior \u00e9s molt fina i permet veure perfectament les seves c\u00e8l\u00b7lules.<\/p>\n\n\n\n

Primer hem agafat un tros molt petit de la pell interior de la ceba. <\/strong>L\u2019hem posat amb cura sobre un portaobjectes<\/strong>. Hi hem afegit una gota d<\/strong>e colorant (betadine) i una mica d’aigua. <\/strong>Hem tapat la mostra amb un cobreobjectes<\/strong> i l\u2019hem observat amb el microscopi<\/strong>.<\/p>\n\n\n\n

Hem descobert que la ceba est\u00e0 formada per moltes c\u00e8l\u00b7lules de forma rectangular, ben ordenades com si fossin rajoles de paret. Algunes c\u00e8l\u00b7lules tenen un petit punt m\u00e9s fosc que era el nucli on hi ha tota la informaci\u00f3 necess\u00e0ria perqu\u00e8 la c\u00e8l\u00b7lula pugui viure.<\/p>\n\n\n\n

Ha estat fascinant veure-ho!<\/p>\n\n\n\n
