Points importants du cours : <\/p>\n

1. Reproduction sexu\u00e9e : Elle n\u00e9cessite deux parent et produit un organisme qui est g\u00e9n\u00e9tiquement diff\u00e9rent de ses parents. <\/p>\n

2. F\u00e9condation : Le noyau d’un spermatozo\u00efde rencontre le noyau d’un ovule pour cr\u00e9er une cellule \u0153uf.<\/p>\n

3. G\u00e8nes et h\u00e9r\u00e9dit\u00e9 : Chaque parent fournit la moiti\u00e9 du mat\u00e9riel g\u00e9n\u00e9tique de l’organisme.<\/p>\n

Consignment: \" Voici un exercice pour tester ta connaissance de la reproduction sexu\u00e9e! Ne te pr\u00e9cipite pasprends entre 10 \u00e0 20 minutes pour le r\u00e9aliser. Lorsque tu as termin\u00e9v\u00e9rifie ta compr\u00e9hension en utilisant les r\u00e9ponses sugg\u00e9r\u00e9es sous chaque question ouverte.<\/p>\n

Exercice :<\/p>\n

1. Explique avec tes propres mots ce qu’est la reproduction sexu\u00e9e.<\/p>\n

2. Quelle diff\u00e9rence y a t’il entre une cellule \u0153uf et les cellules des parents ?<\/p>\n

3. Qu\u2019est-ce que l\u2019h\u00e9r\u00e9dit\u00e9 ? Comment \u00e7a fonctionne?<\/p>\n

R\u00e9ponses :<\/p>\n

1 \" La reproduction sexu\u00e9e est quand deux organismes parents (homme et femme) produisent ensemble un nouvel organisme qui partage leurs caract\u00e8res g\u00e9n\u00e9tiques dans une proportion d\u00e9finie (50% chacun).<\/p>\n

2\" Une cellule \u0153uf est form\u00e9e par la fusion des noyaux d’un spermatozo\u00efde et d’un ovule lors de la f\u00e9condation alors que les cellules des parents ont \u00e9t\u00e9 s\u00e9par\u00e9es durant la m\u00e9iose avant leur rencontre pour former cette nouvelle entit\u00e9 vivante.<\/p>\n

3\" L\u2019h\u00e9r\u00e9dit\u00e9 d\u00e9signe le passage ou transfert des caract\u00e8res biologiques \u2013 comportementaux ou physiques \u2013d\u2019un individu \u00e0 ses descendants par l\u2019interm\u00e9diaire des g\u00e8nes transmis \u00e0 chaque g\u00e9n\u00e9ration.<\/p>\n

Cet exercice convient aux \u00e9l\u00e8ves dysorthographiques car il s’appuie sur leurs forces – une compr\u00e9hension orale solide – tout en offrant opportunities for practice \u00e9criture avec aide au besoin . Il permet aussi aux \u00e9l\u00e8ves de travailler leur vocabulaire sp\u00e9cifiqueS necessary for science courses .<\/p>\n","protected":false},"excerpt":{"rendered":"
