Water lily has a very peculiar habit that it can sleep. Of course, water lilies don't sleep like humans
In the evening of every day, the sun sets and the night falls. At this time, in the middle of the night, the water lily will slowly fold up the petals until they close. At 8 or 9 o'clock in the morning, when the sun is gradually bright, the water lily will wake up slowly and raise its head gradually. By noon, the water lily will have beautiful flowers. This is the process from "sleeping" to "waking up".
Because of the characteristic of the water lily, which wakes up at sunrise and closes at sunset, it is just like a person sleeping. Therefore, the name of water lily is very appropriate. So, is water lily really sleeping?
Actually, the water lily is not sleeping. It's a trick of sunshine. The water lily itself is very sensitive to sunlight. The reason why the petals of water lily open and close when the sun shines
In the morning, the petals of the water lily will slowly open. Because at this time, the outer side of the closed petals of the water lily is exposed to the sunlight, the growth will be slower, the inner side is the back of the sun, it will quickly expand, at this time, the flowers of the water lily will bloom.
At noon, the flowers of the water lily will stretch into a big disc. At this time, the inner side of the petals of the water lily will be irradiated by one, and the growth will be slower. On the contrary, the outer side will grow faster, which will make the flowers of the water lily close slowly. The water lily will "fall asleep".
