①It is easy to believe that the daily life of a plant is simple and boring.They seem to just stand there and sunbathe.In fact，plants are always busy doing many things.Measuring（估量） light is one of them.This activity helps plants to plan better for the future.
   ②To start with，we should know how plants feel the light.In fact，there are some special proteins（蛋白質(zhì)） in their cell（細(xì)胞）.Once receiving light，they will call on other cells to produce，resulting in（導(dǎo)致） the growth towards the light.
   ③Then what can plants get from measuring the changes in the amount（數(shù)量） of daylight？This helps them to tell what time of the year it is.If a plant is beginning to get more daylight，it knows it's spring.Because of this，it may then start producing flowers.
   ④If the amount（數(shù)量） of daylight starts to get low，the plant knows that autumn is coming.It may start to store "food"for its growth.For example，the potato plant will make tubers（塊莖）—the potatoes that we eat.
   ⑤Plants record not only the amount of daylight they receive，but also the quality（質(zhì)量） of light.Some forms of light can help plants grow better.Direct sunlight，for example，works better than light that is being separated through the leaves of other plants.A plant can't get the right form of light when it is prevented from getting light by other plants.It may then begin to grow taller or produce larger leaves in order to get more sunlight.
