? Plants also have eyes

? Animals have eyes, which we can see, but where are the "eyes" of plants? Its "eyes" are photoreceptors on plant cells. Depending on the "eyes" of photoreceptors, plants can not only "see" light, but also "feel" the wavelength of light and the time and intensity of illumination. It is precisely because plants have "eyes" that they can bloom, change leaves and take root according to time.

? Plants love listening to music

? If you put headphones on plants and let them enjoy music for three hours every day, you will find that plants listening to music grow significantly faster. According to botanists' research, most plants like music to varying degrees. Music itself is a kind of rhythmic sound wave vibration, which can produce a * * * effect on plant cells and accelerate plant metabolism. The higher the frequency of music, the more obvious the * * * effect. Of course, there are also plants that don't like music. There is a plant in Africa called Maihe, which is particularly disgusted with music. Ultrasonic waves with a frequency higher than 2 Hz can kill it.

? Plants need to sleep

? Plants must have a "sleep state" for growth. Such as acacia, leaves hang down at night. In fact, plant "sleep" is not only beneficial to growth, but also can better protect itself. Leaves of plants such as peanuts and sweet potatoes hang down in the night, which not only reduces the heat emission, but also avoids the transpiration of water; Petals such as peony are closed at night to prevent natural disasters.

? Plants are born masters of balance

? Starch particles contained in some tree cells will move under the action of gravity to tell the tree that it is crooked. Not only that, trees are all receptors that can measure the change of the inclination angle of the trunk. They relay information along the radial direction of the trunk section, so that trees can feel their local bending.

? Plants can also meet the enemy alone

? We have long known that when Robinia pseudoacacia or poplar is eaten by ruminants, it will secrete tannic acid that turns off ruminants' appetite. However, plants still put the main poisoning energy on herbivorous insects, which is the enemy they want to face.

? Plants have memories

? As we all know, as soon as the mimosa feels the touch, its leaves will immediately close, and when the flowerpot is suddenly lifted, it will make the same reaction. If we lift the flowerpot five or six times in a row, it will take it as it is. Because the mimosa "understands" that it is not dangerous to be lifted, it no longer folds its leaves. Mimosa can keep the memory of this class for about 4 days.

? The prickly melon is sensitive to touch

? In order to find a "backing", the Cucurbita spinosa, which can only climb to other plants, grows an organ with extremely sensitive touch: tendrils, which rotate and stretch like the palm with five fingers open, looking for a support point so as to be entangled and attached to it. Place a weight of only on the tendrils. 25 grams of thin thread, it can quickly curl up. In contrast, human hands can only feel thin lines weighing more than 2 grams.

? Old plants care for the younger generation

? Older trees will take good care of their younger generations, and some radioactive sugar has been transferred to many surrounding trees, mainly from older trees to small trees under their feet. The former is flourishing and takes good care of their descendants like "mother trees". This is the hard evidence that generations have been in the same boat through thick and thin and never give up. The underground bacteria connected to the roots form mycorrhiza and are also responsible for transferring some sugar.
