Weeds, which are very common in the flower market, are the first plant to be touched by many young children, with the strange characteristics of a poach. Scratched grass is also a frequent feature of children's studies。
And weeds, and weeds, which are of age-old grass, in the form of shrubs. This touch was the first to be found in the seventeenth century by a french missionary in brazil who brought it back to france. Later, weeds were spread around the world as a widely distributed tropical plant. During the years of the chong dynasty, the french missionary tomonaga came to our country for his service to the emperor. Today, except in the flower market, you can see wild grass in many parts of the south, and it has become a weed in parks and grasses。
The secrets of shy grass are hidden in its lobes and the base of its lobes, all of which have a slightly larger cystic structure called a leaf pillow. Usually, the leaves pillows are filled with moisture and cell fluids, supporting the blades to remain active. However, when stimulated by external forces (including touch, vibration, temperature change, etc.), the moisture and cell fluids in the leaves pillow quickly flow elsewhere, leading to a shrinking of the leaves pillows, and to the loss of support and convergence of the leaves. This phenomenon is referred to as a shock movement, a rapid reaction of plants to external stimulation。
What's the point of a shock movement with shamegrass? It was argued that it was a defensive mechanism that protected itself from herbivores or other damage. It was also suggested that it was a water-saving mechanism that could reduce the consumption of water evaporation and light cooperation. It was also considered to be an adaptation mechanism that could regulate its temperature and light intensity. In any case, the shock movement with the weed is a very magical and interesting biological phenomenon that deserves our exploration and appreciation。
However, weeds are cute but toxic and require attention when growing. The whole strain of the herb contains a toxic amino acid, known as the herbic acid, which inhibits the synthesis of proteins and affects cell division and growth. Long-term or large-scale exposure or consumption of shampoo may result in adverse effects such as yellowening of hair, skin allergies, liver damage, etc. Therefore, when raising herbs, care must be taken to avoid touching its leaves and flowers (which are certainly not possible, and wash hands later), especially for pregnant women and children. In addition, weeds release toxic substances at night, so it is better not to be in bedrooms or closed spaces。
