Why Does the Sensitive Plant Shy Away? An Explanation of the Reasons
In nature, there is a magical plant that is very "shy" - as soon as it is touched by something, it bashfully folds up its leaves. People vividly named this plant the sensitive plant (Mimosa pudica). Why does the sensitive plant "shy away"? Today, the editor will take a look with everyone at the reasons behind the sensitive plant's shyness.
The sensitive plant (Mimosa pudica) is a perennial herbaceous plant, a low-growing plant native to the tropical regions of South America. Because it closes its leaves when subjected to external force, like a shy little girl, it was vividly named the sensitive plant. It is actually a plant commonly found in moist and warm places, with flowers mostly in white and pink, shaped very much like pom-poms, with fine hairs spread out like a ball of yarn. The sensitive plant is very easy to keep alive, and its flowers, leaves, and fruit all have high ornamental value. So why does the sensitive plant shy away?
The sensitive plant generally grows on grassland with plenty of sunlight. As soon as it is touched by an external force, its pinnae fold up, then the other leaves gradually close, and afterward they droop. Many people find this quite astonishing. In fact, this is a relatively common plant movement phenomenon in the plant kingdom.
Because there is a very large vacuole inside its leaves, and at the position between the leaf and the petiole there is a structure scientifically called the pulvinus. When these parts are stimulated, some sensory cells inside with relatively low electrical potential immediately release water, and then the petiole droops. Because the leaves lose water, they lose the turgor between their internal cells, causing the leaf blades to close. In fact, they also close at night, all because of the internal cell turgor pressure. In fact, its principle is the same as that of the Venus flytrap.
The shyness principle of the sensitive plant has a lot to do with its original environment. Because in tropical regions, water is plentiful and rainy weather is frequent, the sensitive plant closes its pinnae in time to prevent wind and rain from damaging its leaves. In fact, this is also a manifestation of evolution in nature.
The sensitive plant shies away not because it has human nature, but because it has its own unique structure. The above is an introduction to the reasons why the sensitive plant shies away. If everyone wants to know about more magical plants, you can continue to follow our Yihao Home Network!
