Flowers that defend their mission

  In our impression, the flowers seem to be “weak and windy.” As long as the flower stem is gently shaken, or a small wind blows, they will fall to the ground. Sometimes you only need to squeeze gently, their delicate body will shatter, and then quickly wither. However, the latest research by Professor Scott from the University of Portsmouth in the UK has overturned our imagination: flowers are actually not as fragile as we thought.
  Different flowers also have different shapes. Flowers with multiple cut planes that pass through the central axis of the flower and can be divided into two equal halves are called “radial symmetry flowers”; and there is only one that passes through the central axis of the flower and can be divided into two equal halves. Half-cut flowers are called “symmetrical flowers on both sides.” Professor Scott discovered that after the flowers of “symmetrical flowers on both sides” are injured by the outside world, the injured flowers can adjust their positions and defend their right to grow seeds (reproduction) tenaciously.
  The nectaries of flowers secrete nectar, which attracts nectar-gathering insects such as bees. When insects gather nectar between flowers, they will inadvertently rub the pollen on the stamens and bring the pollen to the stigma of the pistil, completing the pollination, and the flowers will eventually grow seeds (and often fruits). It can be seen that the role of flowers is to form seeds in the end, and this is its mission.
  Although the structure of the flower is not complicated, it is very important to keep the various parts in the correct position. Only when the pollen tube, stigma and other sexual organs are in the correct position, insects can successfully pollinate. After being bumped or even stepped on, the position of various parts of the flowers will be abnormal, making it difficult to successfully pollinate. Professor Scott found that some injured flowers are very tenacious. Within 48 hours after being hit, their flower stems will bend down, rotate and move appropriately, twist themselves back to the most suitable position as possible, and ensure that the stigma is in good condition. The location is convenient for receiving pollen. The younger the flower stem, the faster it rotates and moves. However, this phenomenon generally only occurs on two-sided symmetrical flowers, such as goldfish, orchids and sweet pea. These flowers have the ability to move the stem that supports a single flower, and even move the stem that supports a cluster of flowers and restore the position of each part of the flower. . Radiation-symmetric flowers, such as petunia, buttercup, and wild rose, lack this ability, and their flowers often fail to recover after being injured.
  However, the twist and movement of the flower stems after the flower is injured is not only for seed setting, it has other purposes-through careful research, it is found that the twist and movement of the flower stems also help their leaves face the sun again, and more Good photosynthesis. It can be seen that the flowers that we see as “weak and invulnerable” are actually fighters who can resist bad conditions.
