Why do mung beans that bask in the sun grow faster than those that don t

In the early stage of growth, when the mung bean has not yet formed leaves, the mung bean in the sun grows fast because the temperature affects the catalytic efficiency of the enzyme, and the catalytic efficiency of the enzyme is higher when the temperature is suitable, and the catalytic efficiency of the enzyme affects the rate of plant metabolism, the higher the catalytic efficiency of the enzyme, the faster the metabolism speed, and the faster the plant will grow.

If the mung bean has germinated and has grown formed leaves, then there is another factor, which is that sufficient light increases the rate of photosynthesis, thereby increasing the accumulation of organic matter, so it grows faster.

Because of photosynthesis. Photosynthesis is the use of light energy to convert it into chemical energy that the plant itself can use, so it grows better than without photosynthesis. What I would like to add is that legumes are carbon-4 plants. The efficiency of photosynthesis is higher than that of carbon-3 plants

We can clearly understand that it is b-rays that are easy to cause sunburn; In other words, when you happily go to the beach and get red and sore, and you shed a layer of skin, it is the short-term effect of ultraviolet B light. The "indoor ultraviolet tanning method" is to use the principle of "seeking good fortune and avoiding evil", avoiding ultraviolet B light and only using ultraviolet A light, so that the tanning effect can be achieved in the short term, but there is no concern about sunburn. That is, in a machine equipped with many ultraviolet A tubes, the exposure time is gradually increased to achieve the purpose of gradual darkening.

Of course, whether "black" and "beauty" can be equated is a matter of opinion.

Health education often says that you need to spend more time in the sun to be healthy, saying that in this way you will have sufficient vitamin D; This is only half true. According to research, except for infants and young children, we only need a little sun exposure every day to meet our body's needs for vitamin D. Unless you're like the little dragon girl who hides in the tomb all year round, it's not easy to be deficient in vitamin D.

High temperature will affect the catalytic efficiency of enzymes in seeds) The catalytic efficiency of enzymes may be the largest when the temperature is suitable, so it grows fast, and when seeds germinate, they consume their own organic matter, not synthesize, and seeds cannot photosynthesize, how can they be carried out without chloroplasts?

The mung beans basking in the sun have strong photosynthesis and a lot of synthetic organic matter, so they grow well.
