Les cactus peuvent survivre dans les r\u00e9gions arides ainsi que dans les climats humides et m\u00eame tropicaux.  <\/p><p>Les cactus ont une tige succulente, des pointes au lieu de feuilles et des racines courtes et fibreuses. La plupart des esp\u00e8ces de cactus sont consid\u00e9r\u00e9es comme des arbustes \u00e0 feuilles persistantes, tandis que certaines sont consid\u00e9r\u00e9es comme des arbres ou des g\u00e9ophytes. <\/p><p>La hauteur d\u2019un cactus varie d\u2019un centim\u00e8tre (<em>Blossfeldia liliputania<\/em>) \u00e0 quinze m\u00e8tres (<em>Carnegiea Gigantea<\/em>). Sa croissance annuelle peut atteindre jusqu\u2019\u00e0 un m\u00e8tre. <\/p><p>Certains cactus peuvent vivre plus de 200 ans, tandis que d\u2019autres esp\u00e8ces ne vivent qu\u2019environ 15 ans.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ae5e97e elementor-widget__width-inherit elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"ae5e97e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c297e24 elementor-widget__width-initial elementor-widget-tablet__width-inherit elementor-widget elementor-widget-heading\" data-id=\"c297e24\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">3.

Le cactus utilise les stomates de la tige pour laisser entrer le dioxyde de carbone n\u00e9cessaire \u00e0 la photosynth\u00e8se. Les stomates sont de petits pores qui s\u2019ouvrent la nuit. Lorsqu\u2019ils sont ouverts, l\u2019eau peut s\u2019\u00e9couler du cactus.   <\/p><p>Par cons\u00e9quent, les stomates ne s\u2019ouvrent que pendant la nuit lorsqu\u2019il fait plus froid et moins d\u2019eau peut s\u2019\u00e9vaporer (m\u00e9tabolisme de l\u2019acide crassulacien \u2013 CAM). De plus, les cactus ont moins de stomates que les plantes normales. Les cactus ont entre 15 et 70 stomates par millim\u00e8tre carr\u00e9, tandis que les plantes normales en ont plus de 100 par millim\u00e8tre carr\u00e9, selon les auteurs Arthur Gibson et Park Nobel dans leur livre The Cactus Primer.  <\/p><p>Les cactus sont recouverts d\u2019une cuticule \u00e9paisse et cireuse qui retient l\u2019eau \u00e0 l\u2019int\u00e9rieur du cactus et l\u2019emp\u00eache de s\u2019\u00e9vaporer.<\/p><p>\u00c0 l\u2019int\u00e9rieur du cactus, le tissu parenchymateux peut stocker beaucoup d\u2019eau. Les cactus peuvent m\u00eame s\u2019\u00e9tendre pour stocker autant d\u2019eau que possible. Les nervures \u00e0 l\u2019ext\u00e9rieur d\u2019un cactus emp\u00eachent le cactus de se briser lorsqu\u2019il se dilate.  <\/p><p>Les cactus peuvent absorber l\u2019eau du sol gr\u00e2ce \u00e0 leurs racines superficielles et fibreuses. De plus, de petites racines peuvent pousser d\u00e8s qu\u2019il pleut. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c66d528 elementor-widget__width-inherit elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"c66d528\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-07eb54b elementor-widget__width-initial elementor-widget-tablet__width-inherit elementor-widget elementor-widget-heading\" data-id=\"07eb54b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">4.
