If a man rests at night, will the tree rest at night?

Albert D was right. Photosynthesis is carried out during the day and respiration is performed at night.

The tree rests at night.

Eetu Puttonen of the Finnish Geospatial Institute said our findings showed that the whole tree would hang low at night, and the position of leaves and branches would change.

Although the change is not significant, at most 10 centimeters for a tree about five meters tall, they move regularly and systematically and are well within the accuracy of the scanner.

The results of the experiment showed that the foliage of both trees drooped slowly at night, reaching its lowest point a few hours before sunrise, and that the foliage of the trees would return to their original position within a few hours when morning came.

Difference. It's not "sleeping" in the usual sense of the word, but if the above findings are correct, it's definitely a nocturnal cycle. It is very likely that the drooping of branches and leaves is caused by the loss of water pressure within the tree cells.

Andy Curran of The New Scientist reports that this phenomenon, called "turgorism", is common in most plants.

To put it simply, when photosynthesis stops, the pressure decreases, and the branches and leaves of the plant droop accordingly, resulting in swelling pressure. Andreas Zlinsky, from the Hungarian Centre for Ecological Research in Tihhony, explained to the journal New Scientist that "this means that the plant's shoots and stems are less stiff and therefore more likely to hang low under the pressure of their own mass." ”

The research team also said that the low-hanging branches and foliage may be the tree giving its branches a "holiday break". Normally, trees stretch their foliage during the day to absorb more sunlight, but continuing to maintain their posture at night is a waste of "physical energy". However, for a deeper understanding, the research team needs further research.

The main findings of this study show that the branches and leaves of the trees hang slightly at night, as if they are sleeping. While it may not be accurate to call this phenomenon "sleeping," at least this is the first time researchers have recorded a tree's nocturnal cycle to date.

Hello! Trees need to rest at night.

You can find it by looking at some varieties of trees.

During the day, the leaves are completely open in the direction of the light, and the flowers are also fully open in the direction of the light.

As the light diminates at night, the leaves gradually close and droop, and the flowers gradually close and enter a state of rest.

One person who is concerned about the survival of trees in the city said that too much night lighting will make the trees in poor condition, and if small wires and lights are wrapped around the trees, then their health will decrease, because they are also like people, they do not want to be entangled and illuminated at night.

Hope it helps, hopefully.

Most green plants light and act during the day through daylight. Absorbs carbon dioxide to produce organic matter and oxygen. At the same time, it also performs respiration.

Absorbs oxygen to break down organic matter and releases carbon dioxide. In the evening, the plants rest. Stop photosynthesis and only respiration.

It's the same with us. Breathe during the day when you work and when you sleep at night.
