Find out the reason why the flower buds closed at night

If you've ever walked through the night garden, you probably noticed that some colors at night are closing their buds. There are several theories as to why this is happening.

In fact, tulips, hibiscus and other plants that cover the buds after sunset, have a complex natural organization. During the closing and opening bud dorsoventrally responsible organs of plants that create the so-called nasticheskie movement or just the present - movements due to a general change in some factor (light, temperature, etc.). Tulips and other flowers grow such as light and heat, so with the onset of the dark time of day and temperature decreases occur termonastii.

It is believed that in this way the flowers are protected from the coolness of the night, which may be detrimental to the development and growth of these delicate plants: such a position, in particular, held by Charles Darwin, but in a scientific environment, there is no consensus on this matter. Other botanists believe that through termonastiyam flowers just conserve energy and flavor to the day period when pollinating insects are more active. There is a third point of view: that the closed bud does not allow the pollen to get wet from the dew, and dry pollen, insects are easier to carry, therefore, the process of breeding plants will be faster. And finally, the latest theory is that nasticheskie movement - a protective reaction: the flowers are closed to hide his buds from nocturnal predators such as owls, emerging to hunt at dusk and can accidentally damage them.

It is difficult to say which of these versions is closer to the truth, but it is clear that in nature there is nothing accidental, and if the flowers are brought together on the night of their buds, then it is necessary.
