Do water lilies sleep?

Water lilies have a very peculiar habit, which is that they sleep. Of course, water lilies don't sleep like humans do.

Every evening, when the sun sets and night falls, the water lilies will slowly fold their petals until they close in the darkness. At 8 or 9 o'clock every morning, as the sunlight gradually becomes brighter, the water lilies will slowly wake up and gradually raise their heads. By noon, the water lilies will bloom beautiful flowers. This is the process of water lilies from "sleeping" to "waking up".

Because of the characteristic of water lilies that they wake up at sunrise and close at sunset, just like people sleeping, the name "water lily" is very appropriate. So, are water lilies really sleeping?

Are water lilies really in water lilies?

In fact, the water lilies are not sleeping, this is a trick of the sunlight. Water lilies themselves are very sensitive to sunlight. The reason why the petals of water lilies open and close when exposed to sunlight.

In the morning, the petals of the water lilies slowly open. Because at this time, the outer side of the closed petals of the water lily is exposed to the sunlight, its growth will slow down, while the inner side is not facing the sun and will open quickly. At this time, the water lily flower will bloom.

At noon, the water lily flower will stretch out into a large disk. At this time, the inner side of the water lily petals will be exposed to the radiation and its growth will slow down, while the opposite will happen on the outer side, which will grow faster and cause the water lily flowers to slowly close. The water lilies will "fall asleep".
