Arrived spring, I like to play in the park most, because over there have various flowers. The winter jasmine flower that has yellow, peach blossom that has pink, Chinese rose flower that has snow-white pear flower, red, extremely beautiful. But, do you know why the flower is of multicoloured?

到了春天,我最喜欢到公园里玩,因为那里有各种各样的花。有黄色的迎春花、有粉色的桃花、有雪白的梨花、红色的月季花等,漂亮极了。可是,你知道花为什么是五颜六色的吗?

Below father's help, we consulted together computer data. Original, the color of the flower basically is by the flower medium pigment is decided. Beautiful pigment basically has kind of carotene and cyanine element two kinds. Kind of carotene in leaf can make leaf presents a yellow or orange, and the cyanine element in leaf can make leaf presents a red, blue or purple. If composition fruit does not contain any pigment inside petaline cell, so opening the flower that give can be white.

在爸爸的帮助下,我们一起查阅了电脑资料。原来,鲜花的颜色主要是由花中的色素决定。花的色素主要有类胡萝卜素和花青素两种。花瓣中的类胡萝卜素能够使花瓣呈现出黄色或者橙色,而花瓣中的花青素则可以使花瓣呈现出红色、蓝色或紫色。如作文果花瓣细胞里面不含任何色素,那么开出的花就会是白色的。

The content of the pigment in the depth of beautiful color and leaf has very big concern, pigment content is high, beautiful color is met a few deeper; Pigment content is low, beautiful color is met a few more shallow. Perhaps you still can ask: Why do some beautiful color often change? Because be in,this is early, medium, evening of a day, alkalinity of petaline cell fluid is different and cause.

花的颜色的深浅与花瓣中色素的含量有很大关系,色素含量高,花的颜色就会深一些;色素含量低,花的颜色就会浅一些。也许你还会问:为什么有的花颜色经常变化呢?这是因为在一天的早、中、晚间,花瓣细胞液碱度不一样而造成的。

The secret of nature still has a lot of, the child ability that is good at observation only finds the solution. I should do an attentive observation, person that is good at thinking, discover nature more secrets.

大自然的秘密还有很多,只有善于观察的小朋友才能找到答案。我要做一个细心观察、善于思考的人,发现大自然更多的秘密。(文/石佳琪)
