Celui-ci est compos&eacute; de diff&eacute;rentes &#8220;ondes&#8221; &eacute;mises par le soleil, dont certaines sont visibles par les humains sous forme de couleurs, alors que d&rsquo;autres leur sont invisibles (par exemple les ultraviolets). Chaque onde correspond aussi &agrave; de l&rsquo;&eacute;nergie. Les feuilles des plantes contiennent des compos&eacute;s chimiques appel&eacute;s &#8220;pigments chlorophylliens&#8221; qui absorbent les ondes du rayonnement solaire&#8230; mais seulement la moiti&eacute; de celles qui correspondent &agrave; la couleur verte. Ces &#8220;ondes vertes&#8221; n&rsquo;&eacute;tant pas retenues dans les feuilles, elles sont r&eacute;fl&eacute;chies&#8230; et nous pouvons donc les voir ! Voil&agrave; pourquoi les feuilles nous apparaissent vertes. Ce que les feuilles font avec les ondes capt&eacute;es ? Elles se servent de leur &eacute;nergie pour r&eacute;aliser la photosynth&egrave;se, un processus qui transforme l&rsquo;&eacute;nergie lumineuse en &eacute;nergie chimique puis en sucre, utilis&eacute; par la plante pour se d&eacute;velopper. &raquo;<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"Pour r&eacute;pondre &agrave; cette question, il faut commencer par parler du rayonnement solaire.
