单项选择题

花朵的红色是热情的色彩,它强烈、奔放、激动,令人精神振奋。红紫烂漫的春天,多么活力充沛,生气蓬勃。“花儿为什么这样红 ”是我们对它的赞叹和歌颂,同时也不妨对它作一科学的解释。
“花儿为什么这样红 ”首先有它的物质基础。不论是红花还是红叶,它们的细胞液里都含有由葡萄糖变成的花青素。当它是酸性的时候,呈红色,酸性愈强,颜色愈红。当它是碱性的时候,呈现蓝色,碱性较强,成为蓝黑色,如墨菊、黑牡丹等。而当它是中性的时候,则是紫色。万紫千红,红蓝交辉,都是花青素在不同的酸碱反应中所显示出来的。
还有“战地黄花分外香”的菊花,“金英翠萼带春寒”的迎春花,都呈黄色。菊科植物除了黄花以外,还有橙色的花。橙色与柑橘、南瓜等果实的颜色相似,而最典型的是胡萝卜,所以表现这种色彩的色素,就被称为胡萝卜素。
至于白花,那是因为细胞液里不含色素的缘故。有些白花,例如菊花,萎谢之前微染红色,表示它这时也含有少量的花青素了。变色的一个特殊例子是添色木芙蓉,早晨初开白色,中午淡红,下午深红,一日三变,愈开愈美丽。又如八仙花,初开白色微绿,经过几天,变成淡红,或带微蓝,它不像添色木芙蓉那样朝开暮落。至于一般的花,大都初开时浓艳,后渐淡褪。
“花儿为什么这样红 ”还需要用物理学原理来解释。太阳光经过三棱镜或水滴的折射,会分成红、橙、黄、绿、青、蓝、紫七种颜色。这七种颜色的光波长短不同,红光波长,紫光波短。酸性的花青素会把红色的长光波反射出来,送到我们的眼帘,我们便感觉到是鲜艳的红花。同样,中性的花青素反射紫色的光波,碱性的花青素反射蓝色的光波,胡萝卜素有不同的成分,便分别反射黄色光波或橙色光波。白花不含色素,但组织里面含有空气,会把光波全部反射出来。

下列哪个是文中提到的可以变色的花

A.菊花

B.迎春花

C.胡萝卜

D.八仙花
