The above is wrong, plants mainly absorb the spectral range of red-green light and blue-violet light, why can't artificial light carry out photosynthesis???
As long as photosynthesis is carried out, starch (and some other substances) will be produced, which is used as a plant, so it is beneficial to the growth of plants, but the time should be well controlled, not that the more light hours, the better, will destroy the balance of a plant itself
-
Of course! At least it helps to increase crop yields, and some modern vegetable producers use red light as a light source to increase yields.

It is correct to say that there is only a dark reaction, and there are two parts of light and effect: light reaction and dark reaction Light reaction is only when there is sunlight, dark reaction can be carried out with light and no light In the dark, there is only a dark reaction, and then the plant is only respiring for survival, and there is no light reaction As for the use of artificial light, it can make it react with light, and at this time, plants are also producing organic matter, which is advantageous for human beings, and can improve the yield of crops But in my humble opinion, This may not be entirely a good thing for plants, although this allows them to grow at night, but nature has its own laws, and it is useful to only breathe at night, and nature always has its own reason

It's not a question of profitability.
Anthropogenic light plants cannot photosynthesize at all.

It's good for people, but not necessarily for plants.

What are the effects of street lighting on plants at night? Is it beneficial or harmful?
Hello! Studies have shown that in low light, light can inhibit plant dormancy, thereby promoting growth, and is conducive to plant photosynthesis, but there is an upper limit to the light intensity required by plants, that is, the light saturation point. When the light intensity reaches the upper limit, the photosynthesis reaches its strongest, and when the upper limit is exceeded, it will cause the plant to produce photoinhibition and reduce the photosynthesis of the plant, which will have an adverse effect on the plant!
-
It is used for photosynthesis and respiration during the day and at night. It's just that the sunlight is strong during the day, and photosynthesis is stronger than respiration. At night, because there is no light or very little light, the plants mainly do respiration.

Plants photosynthesize and respire during the day and photosynthesize and respire at night.

Photosynthesis of <> plants refers to the process in which green plants use light energy to convert carbon dioxide and water into organic matter that stores energy and release oxygen through chloroplasts. The process of photosynthesis is divided into two phases: the light reaction phase and the dark reaction phase.
The chemical reaction in the first stage of photosynthesis must have light energy to proceed, and this stage is called the Kunachang photoreaction stage. The chemical reaction in the photoreaction stage is carried out on the thlakoid chakra within the chloroplast.
The chemical reaction in the second stage of photosynthesis, which can be carried out without light energy, is called the dark reaction stage. The chemical reactions in the dark reaction phase are carried out in the matrix within the chloroplast.
The light reaction stage and the dark reaction stage are a whole, and in the process of photosynthesis, the two are closely related and indispensable.
In the absence of light at night, plants do not photosynthesize completely, and only have a dark reaction in photosynthesis. A dark reaction is essentially a series of enzymatic reactions. Different plants have different processes of dark reactions, and the anatomy of the leaves is also different, which is the result of the plant's adaptation to the environment.
Therefore, nocturnal plants undergo incomplete photosynthesis.
-
Plants need sunlight for photosynthesis, and there is no sunlight at night, so photosynthesis cannot be carried out.
The leaves of green plants use carbon dioxide and water to produce nutrients such as starch when exposed to sunlight, as well as release oxygen, a role that is called photosynthesis.
In this process, the green plants in the leaves convert the energy of the sun and light into chemical energy, which is stored in starch and other substances, and at the same time releases oxygen.
-
Plants cannot photosynthesize at night.
Under the illumination of light, green plants can photosynthesize to produce oxygen depletion, but the light intensity of the light must reach a certain intensity. When the light saturation point is reached, photosynthesis decreases with the weakening of light intensity, and when it decreases to a certain intensity, the CO2 absorbed by photosynthesis and the CO2 released by respiration are in a state of equilibrium, and the light intensity at this time is called the light compensation point, at this time, the plant can no longer carry out photosynthesis. Therefore, to be precise, photosynthesis can be carried out when the light intensity is above the light compensation point of the green potato plant under light irradiation, and photosynthesis cannot be carried out when it is lower than the light compensation point of the plant.
-
Plants perform photosynthesis and respiration at the same time when sunlight is present; When there is no sunlight, photosynthesis is not carried out, but respiration is carried out.

What are the effects of street lighting on plants at night? Is it beneficial or harmful?
Hello, glad to answer for you. Overall, street lights at night are harmful to plants. At night, the plants grow towards the light, slowly changing their shape, and the light attracts more pests to nearby plants.
-
Yes. As long as there is a light environment, it will do. You can't do it without light. For example, during the day, when you get it to the dark room, the plants can't photosynthesize.
-
Light can also emit red light and blue-violet light, which is absorbed by plants for photosynthesis, and the light is used to irradiate plants in flower production in order to enhance the photosynthesis of plants and early flowering.
Scientific research has found that plants mainly rely on blue-green light and red-orange light for photosynthesis, which are contained in light, so plants can also photosynthesize under light.
Unlike animals, plants do not have a digestive system, so they must rely on other means for their nutrient intake. It's the so-called autotrophs. For green plants, during the sunny day, they will use the energy of sunlight to photosynthesize to obtain the nutrients necessary for growth and development.
You are only 17 years old, if you are a boy, then you are more likely to grow taller, you can insist on playing basketball every day, because proper jumping can make you taller, my classmate's sister, played basketball for two years when she was in college, and she grew three centimeters taller, a very precious three centimeters!!
