<\/p>\nL’alumnat de l’optativa de Biologia de 4t d’ESO hem observat amb el microscopi com es divideixen la c\u00e8l\u00b7lules. Per fer-ho, primer hem hagut de fer cr\u00e9ixer les arrels d’una ceba i aix\u00f2 ens ha perm\u00e8s agafar mostres de la punta de l’arrel, que \u00e9s on hi ha el creixement. Despr\u00e9s hem tenyit les c\u00e8l\u00b7lules amb un reactiu que acoloreix els cromosomes i, finalment, les hem observades al microscopi. Es veia tan b\u00e9 que hem pogut diferenciar les diferents fases de la mitosi, el proc\u00e9s de divisi\u00f3 cel\u00b7lular. Al laboratori, la ci\u00e8ncia pren cos!<\/p>\n
A continuaci\u00f3 us deixem unes quantes imatges de la pr\u00e0ctica:<\/p>\n
