Can plants undergo photosynthesis under light

Plants can also undergo photosynthesis under light, and each plant has similar requirements for light. Photosynthesis mainly relies on blue light and red purple light. As long as the wavelength of this beam of light is in the range of 400 to 700nm and can emit these two types of light, it can be utilized by the leaves of plants for photosynthesis.

The organ for photosynthesis in green plants is their green leaves. The reason why the leaves are green is because a large amount of chlorophyll is distributed in the chloroplasts of the leaf cells. Chlorophyll is a type of cytochrome, divided into chlorophyll a and chlorophyll b, and its function is to capture light energy. Although visible light is the wavelength range used in photosynthesis, the wavelength of light also affects the rate of photosynthesis. Generally, photosynthesis is fastest under red light, followed by blue and purple light, and worst under green light. Obviously, any light source, as long as its emission wavelength is within the range of 400-700nm, can be utilized by leaves for photosynthesis.

So it’s possible.

For example, fluorescent lamps, scientific research has found that plants mainly rely on blue-green light and red orange light for photosynthesis. The fluorescent lamp light contains these two types of light, so plants can also engage in photosynthesis under light. During the Chinese New Year in Guangzhou, lighting is used to illuminate the kumquat trees in order to control their flowering and fruiting.
