From red apples and yellow lemons to blue berries and green melons,fruit comes in many different colours. Why do different kinds of fruit have so many colours?
According to Lu Wei from the Chinese Academy of Sciences,fruit colours ⑴(actual) come from their different pigments(色素),such as red or yellow carotenoid(类胡萝卜素) and blue or purple anthocyanin(花青素). These pigments appear in different amounts,depending on the ⑵(fruit) environment. This causes the fruit ⑶(take) on a certain colour.
To find out how environment affects fruit colours,Chinese scientists ⑷(study) more than 280 different fruit colours,⑸(include) white,red,blue,purple,and black.
They found that red fruit tends to grow in cooler places. And instead of just ⑹(grow) in one place,you can find that they grow in many places around the world. Blue and purple fruit mostly grows in warm places. This fruit tends to grow a lot in just one specific area. The ⑺(science) also found that the ⑻(close) the fruit is to the equator(赤道),the darker its colour will be.
Besides,animals ⑼(have) an impact on the evolution(进化) of fruit colours so far. Animals eat fruit and drop the seeds in other places later. This helps the fruit spread and grow in different places. Therefore,in order to attract animals,some kinds of fruit develop colours that are easy for animals ⑽(see).
