Why are apples, cotton and rice so happy in the gorgeous autumn?

Late autumn, just after the golden autumn, autumn apples are ripe. Farmers' uncles picked red apples from trees, packed them in cartons and sent them to the city. The fruit stalls in the street are full of all kinds of apples, among which the biggest and reddest apple is particularly eye-catching, with a thin layer of slightly whitish frost on its smooth surface, that is, my favorite red Fuji apple.

Grandma bought me a bag of red Fuji apples, about seven or eight of which are about the same size and all red in color. I picked up a red apple that my grandmother had just washed and asked my grandfather, "Why are apples red in autumn?" Grandpa told me: "the apple peel itself is green and contains a lot of chlorophyll." As the weather gets colder and colder, chlorophyll will be converted into carotene and lutein, and the solar terms will become more and more red in the cold first frost. " I looked at the apple in my hand and thought, there are so many mysteries on this apple! I was just about to eat when I suddenly found another deep scar in the apple nest. I quickly asked my grandmother, "Why did you buy a bad apple?" Grandma smiled and said, "Silly Ya Dan, that's called dry scar, very sweet!" "Only apples with more sugar will crack." Grandpa added. Uh-oh, I see. So, I took a big bite, wow! Very sweet. Crispy, apple juice seems to be coming out. I followed it bite by bite, but I didn't expect most of the apples were in my stomach. Grandpa looked at me and said, "Why don't you eat?" I quickly replied: "I know this, the nutritional value of apple peel can be high!" " "

Our hometown is the hometown of apples, especially the red Fuji apples here are well known. Today, I ate red Fuji apples produced in Sanlibao, Jinzhou, which was very delicious.
