Evidence shows that plants also know 'go to sleep' just like humans

Sleep - action seems to be the "privilege" of animals and humans, but it turns out that trees do the same.

Plants and animals, despite their intimate relationship, are completely different in nature. However, previous studies have revealed similarities between tree people, such as the ability to "forget" - which is only found in sentient organisms such as animals or humans.

Trees also know how to sleep like people.

This time too. Scientists in Austria, Finland and Hungary have recently discovered that plants also "sleep" - seemingly the privilege of higher animals.

Every time the sunset falls, the branches will begin to "descend" literally.

More specifically, by laser scanners, scientists find that every time the sunset falls, the branches will begin to "descend" literally. Trees taller than 5 meters will drop to about 10cm.

To clearly identify the impact from climate and location, experts experimented twice, on two different trees in Finland and Austria. Both areas have no wind or condensation.

The results showed that only a few hours after the sun set, the branches began to descend. By the time it was bright, they gradually returned to their old positions.

This phenomenon may come from pressure inside the cell.

Experts say this phenomenon may come from pressure inside the cell - which is directly related to photosynthesis. When night falls, photosynthesis stops, the process of synthesizing sugar accordingly decreases, causing the pressure to drop.

This allows plants to really rest, after a long day taking advantage of pressure to direct the leaves towards the Sun.

Photosynthesis process of plants

However, experts have not yet agreed on why trees can wake up: thanks to the Sun or their habits. According to András Zlinszky, a researcher at the Hungarian Academy of Sciences: "Plants can move based on the balance of water between cells, which is directly affected by light through photosynthesis."

He said that it was difficult to observe trees in bed before, because traditional methods all use light. But with lasers, interference is no longer significant.

With this finding, experts have officially acknowledged that plants also sleep, thus better understanding the development of plants, and providing applications for plant-related professions.
