Of course, plants also need to sleep. However, their sleep time varies from early to late, from long to short. Whenever the rising sun rises in the east, the beautiful water lily slowly unfolds its petals, as if it has just awakened from a dream. But as soon as the sun sets, it closes its petals and goes to sleep again; Dandelions bloom every morning at 7 o'clock and close at 5 o'clock in the afternoon. It's really like waking up early and going to bed early; Half lotus is a sleepy guy. It just bloomed at 10 o'clock in the morning and closed its petals to sleep after noon; Some flowers like to work night shifts, such as jasmine, which blooms at 5 pm and doesn't rest until dawn the next day. Saffron is the most interesting. It blooms and closes at times throughout the day, it's like waking up and sleeping, sleeping and waking up again, feeling groggy all day long!
Are plants also sleeping for rest? Besides resting, plants also have many other functions when it comes to sleep! Sleeping at night with flowers and leaves can not only prevent cold, but also reduce water evaporation and avoid insect disturbance.
Not only do plant flowers need to sleep, but plant leaves also need to sleep. The first person to discover leaf sleep was the famous British biologist Darwin. After research, he concluded that the sleep movement of plant leaves can protect them from the cold of the night. Later, scientists discovered that the sleep movement of some plant leaves is not related to temperature, but is caused by changes in the turgor pressure of some cells at the base of the petiole, such as Acacia, Oxalis, and Trifolium repens.
