Do plants need oxygen when the sun is shining?

1 Oxygen is not required from the outside world. During the day, when the sun is shining, plants produce more oxygen than they consume, producing enough oxygen for them to breathe. Therefore, what we call oxygen production is net oxygen (that is, oxygen production - oxygen consumption).

2 Plants produce carbon dioxide during cellular respiration, but it is then used by themselves for photosynthesis.

3 Because photosynthesis requires light, it only undergoes cellular respiration at night, consuming its own organic matter and oxygen, and exhaling carbon dioxide.

In the sun, aerobic respiration and photosynthesis occur at the same time.

In other words, carbon dioxide is still produced in the mitochondria, and then the carbon dioxide produced is directly given to the chloroplast.

So don't exhale carbon dioxide.

At night, it is true that only aerobic respiration is carried out, and no photosynthesis is carried out, oxygen is consumed, and carbon dioxide is released.

When the sun is shining, the mitochondria in plant cells still undergo aerobic respiration to produce carbon dioxide. In other words, plants still need oxygen, but the oxygen produced by plants through photosynthesis can meet the aerobic respiration needs of plants, so it is manifested as no carbon dioxide exhalation.

Oxygen should still be needed because aerobic respiration and photosynthesis are taking place at the same time. Aerobic respiration** is carried out in the granula, breaking down ATP to release energy, a process that takes place day and night (as long as life is not dead).

Plants also need oxygen when the sun is abundant, because plants need energy when absorbing trace elements such as iron and magnesium in the soil, and this energy comes from the respiration of root cells.

Plants still need oxygen when the sun is shining, it's just that because photosynthesis produces enough oxygen, plants don't need to get it from the outside world.

Holoparasitic plants such as Cuscuta seed, Liedang, and wild mushrooms, as well as saprophytes such as gastrodia and crystal orchid, have no chloroplasts, and cannot carry out photosynthesis and do not produce oxygen; Photosynthesis is for the purpose of obtaining nutrients, and the oxygen excreted is a by-product, so plants that can produce oxygen without sunlight do not.

Plants that release oxygen at night are:

Cactus: Cactus, Cactus Mountain, Cactus Pillar, Measuring Ruler, Crab Claw Orchid, Haohua, Lingjian, White Sandalwood, etc.

Seventh, Fei Cai, swallow palm, jade lotus, stone lotus, etc., tiger pill orchid: tiger pill orchid, as well as agave, Phnom Penh agave, aloe vera, dragon claw, emerald flower palm, raw stone flower, ground roots, Ji pineapple, Yanhua iron orchid, winged yucca, dwarf garan, centenarian leaves, etc., a total of more than 300 varieties.

Spider plants can survive without light or ventilation. Pothos can also be placed indoors without ventilation and light. It is a plant that absorbs carbon dioxide and releases oxygen, and can survive without ventilation and light.

In addition, monstera, clemat fern, and white palm can also be cultivated indoors.

What plants do not need sunlight can also produce oxygen fairy balls. Clivia. Pothos. Both.

Chlorophyll in the leaves and stems of green plants.

Able to photosynthesize.

Its essence is to convert carbon dioxide.

When it is converted into sugars from water, oxygen and energy are released.

In order for animals to consume oxygen and exhale carbon dioxide, they must rely on green plants to photosynthesize to maintain the balance of oxygen and carbon dioxide in the earth's atmosphere.

The life activities of animals and plants on the earth, especially metabolism and energy metabolism, are all hail shirts that need to consume oxygen.

For example, only when people inhale oxygen from the air, can they oxygenate the organic matter obtained from food, and then produce energy to maintain body temperature and support various life activities of the human body, otherwise without energy, people will die quickly.

Purification of the plant's cavity qi for the great source.

First of all, it can absorb the poisons in the atmosphere through the leaves and reduce the amount of poisons in the atmosphere. Such as plant sulfur dioxide.

It has a strong absorption capacity, so in the sulfur dioxide contaminated area, the sulfur content of plants is 5 10 times higher than that of normal leaves. When plants absorb sulfur dioxide, they form sulphurous acid, which is much less toxic.

As long as the concentration of sulphur dioxide in the atmosphere does not exceed a certain limit, plant leaves will not be harmed and can continuously absorb sulphur dioxide.

The second is that plant leaves can reduce and adsorb powder, such as dense forests can reduce wind speed, so that large particles of dust in the air fall, especially the leaves of some plants are rough and hairy, and some secrete mucus and oil, which can absorb a large amount of dust. Dusty plants can quickly recover their adsorption capacity once washed by rain.

Plants produce nutrients and release oxygen through photosynthesis and are the biological material basis on which other organisms depend.

Need.

Plants also need oxygen during their growth, because plants also have a respiration process, and respiration is to inhale oxygen and discharge carbon dioxide, so this also shows that when the earliest plants on the earth appeared, there was actually oxygen on the earth, but the oxygen content on the earth was not as high as it is now.

The earliest oxygen came from **.

In fact, as long as there is oxygen in the material that forms the earth, then there should be oxygen on the earth, and oxygen will exist in these gaseous substances when the mass of the earth is large enough to support the presence of gases on the earth's surface.

When the earth was first formed, the surface was in a lava state, at this time, when the water-rich comet asteroid landed on the earth's surface, the water vapor would be evaporated in large quantities, and the atmosphere on the earth's surface was relatively thin, and the strong sunlight would decompose the water vapor into hydrogen and oxygen, and the earth's gravitational pull was not strong, and hydrogen could easily escape into space, and the remaining oxygen would remain in the atmosphere.

This is one of the early oxygen levels on Earth, but scientists estimate that the oxygen content at that time was less than 1/10,000 of the current Earth's atmosphere, but it still provided the initial oxygen to the early microorganisms, animals and plants on Earth**, and it can also be said that it was because of the oxygen in the Earth's atmosphere that there were living species.

Yes, in fact, plants need oxygen even in the process of photosynthesis. It's just that during the day, when the sun is abundant, the amount of oxygen they can produce is greater than the amount of oxygen they need, so it looks like the plants are releasing oxygen.

But if the amount of oxygen produced by photosynthesis is less than it needs (for example, at night when there is no sunlight at all and photosynthesis is not possible), the plant also needs to absorb oxygen from the outside world, just like animal breathing.

Respiration does not just mean "respiration", it is the process by which all living cells produce energy. Plant cells are unable to obtain energy by making sugar and releasing oxygen, breaking down sugars and consuming oxygen in order to produce energy for their own use.

Understand why children need air to grow.

The plant normally absorbs carbon dioxide and releases oxygen when its leaves grow during the day, and its leaves absorb oxygen and release carbon dioxide at night. The root system of plants absorbs oxygen from the soil when growing, and when the roots of plants planted in the soil are in long-term water accumulation, they are prone to lack of oxygen and cause root rot and death.

But plants make their own oxygen.

Different plants don't routinely need the most carbon dioxide.

There are many plants that can be raised indoors, such as spider plant, ivy, pothos, bamboo, white palm, tiger piran, fortune tree, rich bamboo, junzi orchid, cactus and so on. These plants are shade-tolerant, well-adaptable, and very ornamental. It is a very long and common plant, and it is more suitable for growing in semi-shady places, so it is very suitable for indoor cultivation.

Moreover, it also has the ability to absorb harmful gases, which can purify the air well in the room. This is a feminine vine that is undoubtedly very suitable for indoor cultivation. It also has the ability to absorb formaldehyde, benzene, etc., generally put 1 2 basins in the room, it can make the air in the room better.

Many flower lovers know that it is a negative plant and will grow better in a relatively shady place, so raising it indoors will not hinder its growth.

All in all, there are many flowers and plants that are suitable for indoor cultivation, and most of them absorb carbon dioxide and release oxygen at night, which can promote people's sleep and improve people's sleep quality. For example, the green plants aloe vera and tiger pill orchid, but also the longevity flower and the fortune flower, we can choose these plants according to our needs.

1. Tiger Piran.

Tiger Piran is an excellent indoor plant, even in the bedroom, it can grow well, and the most important thing is its ability to release oxygen, which can be released 24 hours a day, and at night, it can also absorb carbon dioxide. And the requirements for the growing environment are not high, even in the north bedroom where the light conditions are not very good, it can adapt to growth well.

In the bedroom breeding tiger piran, the only thing to pay attention to is to do a good job of ventilation management, the light conditions in the bedroom are not very good, but also very shaded, after each watering, the excess water is difficult to be consumed by normal leaf transpiration and other methods, the best way is to consume excess water through good ventilation. If the stagnant water is not removed in time, it will definitely cause the potting soil to be too wet, causing all kinds of mold, or simply black rot, and the rotten roots will come up, and it will be a headache to deal with.

2. Aloe vera. Aloe vera is very suitable for maintenance on the windowsill of the bedroom, with strong vitality, thick and green leaves, and basically extensive management. The biggest effect of aloe vera is also to improve air quality, it releases oxygen 24 hours a day, and at night, it can absorb carbon dioxide and some harmful gases. It can also be used as a detector of air quality, and if you find some small red spots on the leaves of aloe vera, it tells you that the air quality around you is not very good.

Aloe vera basically does not need to be managed, as long as the normal ** water and fertilizer, the pot can be full after a year. If it is on the windowsill of the south bedroom, it is best to change the position in summer, although aloe vera is also heat and sun resistant, but long-term strong light exposure, will also have an impact on its growth, when the temperature reaches 35 or more, aloe vera will also enter a short dormant period, you need to control the amount of watering, to prevent high temperature and high humidity caused by root rot.

3. Longevity flowers.

Longevity flowers are a very popular flower among flower friends, the popularity rate is still very high, but how many flower friends know that it is a flower with superb oxygen production capacity, but longevity flowers need to have good light conditions to raise well, and to meet the requirements in general, only the south side of the bedroom, but you can also use more than 2 pots of longevity flowers, take turns to put into the north side of the bedroom, about 20 days a rotation, not only can solve the problem of longevity flower breeding, but also solve the problem of placing longevity flowers in the north bedroom.

Longevity flowers are blooming, and now there are no fragrant and fragrant longevity flowers on the market, you can choose according to your preferences. The longevity flowers in my bedroom are a pot without fragrance, and they are still blooming, and they grow very well in the bedroom. After all, longevity flowers are also a very good flower, and cuttings can live strong vitality.

It's well worth raising a pot.

4. Crab claw orchid.

Crab claw orchid and longevity flower are like hum two generals, the flowering period is similar, the habits are similar, the ability is similar, the leaves of crab claw orchid have a good ability to release oxygen, and it is also suitable for bedroom cultivation of a flower.

There are many kinds of green plants suitable for indoor maintenance, such as pothos, spider plant, bamboo, watercress green, junzi orchid, ivy, happy tree, etc., maintenance indoors will not harm our health, but also purify the air, provide us with a healthier living environment, can also play a role in decorating the home.

From the perspective of their growth, the indoor environment should be conducive to growth. However, it is necessary to open the windows frequently for ventilation to ensure good air circulation.

2.The cells of the green body with leaves and holes are photosynthesized under the premise of light intensity, carbon dioxide and water, and it is possible to release oxygen.

1) When the light intensity is very weak, the oxygen produced by photosynthesis may be equal to the oxygen absorbed and retracted by the mitochondria, and the cells of the plant chloroplast appear to be neither oxygen absorption nor oxygen release.

2) When the oxygen produced by photosynthesis in the absence of light or weak light (or the oxygen produced by the finger withering) is less than the oxygen absorbed by respiration, the cells of the plant chloroplast absorb oxygen from the outside.

3) The chloroplasty cells of plants release oxygen only when the oxygen produced by photosynthesis is greater than the oxygen absorbed by respiration.

3.Chloroplast-free cells, i.e., non-green parts, only respirate and do not photosynthesize. Like a root, he always has to absorb oxygen and oxygen.

4.At the same time as photosynthesis, respiration is carried out, and oxygen is also absorbed at the same time, but the green part of the cell, oxygen is directly transported from the chloroplast to the mitochondria.
