Nocturnal plant respiration, is nocturnal plant respiration vigorous

1 Plants have a cuticular membrane on their stems and leaves, which is neither permeable to water nor breathable, so they need stomata as a gas exchange channel. The stomatal ratio is not completely closed at night, but the gas exchange is reduced (the temperature is low at night, the breathing is not strong, and there is no photosynthesis, so the stomata should be closed to avoid water dispersion and loss).

2 In addition to stomata, there are also parenchyma cells, root hairs, etc., which can exchange gases with the outside world, but stomata are the most important.

3 No, if the root system is hypoxic, it can generally only be respirated without oxygen, but there are special cases. For example, the root system of rice has been in an anoxic environment for a long time, but because there are special mesh ducts in the plant, the oxygen absorbed by the stems and leaves can be transported to the roots, and aerobic respiration can be carried out.

4 Yes, because CO2 is freely diffused and can be excreted by stems and leaves.

First: the stomata of the plant leaves do not close. The stomata of the plant are not closed only related to the water content in the guard cells around the stomata are related, that is to say, the stomatal switch of the plant is related to the content of water in the plant, and the stomata will be closed when the plant is seriously short of water, and the temperature drops at night, and the water absorbed by the root system is sufficient, and the stomata will not be closed; At noon in the hot summer, the water loss rate of plants due to transpiration is much higher than the water absorption rate of the root system, resulting in serious water shortage of plants, and the stomata of plants will be closed at that time;

Second: In addition to the pores where the plant exchanges gases with the outside world, there are skin pores. In the cold winter, the plant has no leaves, but the plant can still carry out respiration and transpiration, mainly by the skin pores in the skin.

There is a famous plant physiologist in China, Pan Ruichi, published "Plant Physiology".

The respiration of plants at night depends on the stomata, and the stomata of the leaves should not be closed at night.

Absorb oxygen at night and release carbon dioxide...

It is also possible to walk from the cell wall.

The landlord asked so many professional questions and didn't give a reward.

During the day, the sun is strong, and photosynthesis is stronger than respiration. At night, because there is no light or there is only very little light in the cherry blossoms, the plants mainly do respiration. Without photosynthesis, plants cannot receive ridge energy.

Without respiration, plants are unable to convert the energy they gain (mainly light) into absorbable organic matter. As long as there is oxygen during the day and at night, it will continue to breathe. But without photosynthetic celebration to provide energy, plants will wither because there is no organic matter.

Comparatively speaking, during the daytime photosynthesis with a large amount of exercise, the respiration must be stronger than at night.

The plants that release the most oxygen at night are: spider plant, aloe vera, pothos, brazilwood, and fortune tree.

1. Spider plant

Spider plant is a kind of potted green plant that purifies the air, put it in the bedroom, can absorb carbon monoxide, nitrogen dioxide and other harmful substances in the air, which is beneficial to human health, and when photosynthesis, it releases oxygen and absorbs carbon dioxide.

2. Aloe vera

Aloe vera is also one of the plants that release the most oxygen, its branches and leaves are thick, the vitality is strong, the adaptability to the environment is strong, even in the poor soil can grow well, there are no high requirements for light, water, just need to let it properly see the light in normal times.

3. Pothos

Pothos is one of the common potted green plants indoors, and the growth rate is fast, the growth is good, it has a strong drought tolerance, the branches and leaves are evergreen all year round, it can absorb carbon dioxide in the air, release oxygen, and put it indoors, which can have a good decorative effect.

4. Brazilwood

Brazilwood is a tropical plant, resistant to high temperatures, the plant can reach about 6 meters, the bark is gray-brown, the leaves are broad, the leaves are lanceolate, like to grow in loose and fertile sandy soil, like light, but also relatively shade-tolerant, avoid dry and drought.

5. Fortune tree

The branches and leaves of the fortune tree are evergreen all year round, can be hydroponic or soil culture, it is more suitable to be placed indoors, it can have the effect of purifying the air, like to grow under high temperature and high humidity conditions, but the cold resistance is very poor, the plant type is beautiful, and the root system is developed.

Nowadays, more and more people like to put a few potted plants in their homes, and any expensive furniture will be overshadowed by the fresh plants that accompany the green.

In addition to looking pleasing to the eye, having plants in your home can also purify the indoor air. But as we all know, green plants release oxygen and inhale carbon dioxide and other gases during the day, and at night they inhale oxygen and emit carbon dioxide. So, do you put plants indoors?

What to put? How much to put? are all topics worthy of our attention.

As for the vigorous respiration of plants at night and the release of carbon dioxide, we can find ways to avoid it, for example, in the room where people are sleeping, we can put less plants, and for rooms with different functions, choose plant tremors with different purification functions, etc.

Due to the vigorous respiration of plants at night and the release of carbon dioxide, it is not advisable to put too many plants in the bedroom; Or move the flowers into the hallway at night and put them back indoors the next morning. Bathrooms, studyes, living rooms, and kitchens are decorated with different materials and polluting substances, so you can choose plants with different quantities and different purification functions.

Plants should be selected according to the size of the room area, and the indoor environment of plant purification is directly related to the leaf surface area of plants, which affects the effect of purification. Generally speaking, in the room, 1 to 2 pots of flowers and plants per 10 square meters can achieve the effect of removing pollution. The plants should also be placed in line with the style of the room.

Plants, like people, breathe day and night. Although plants do not have obvious respiratory organs, every cell of the plant's --- roots, stems, leaves, flowers, fruits, and seeds can breathe.

Plants have two main physiological responses: photosynthesis and respiration. Photosynthesis only takes place during the day, because there is sufficient sunlight during the day, plants absorb water and carbon dioxide, synthesize organic substances (starch) through the chemical action of sunlight and chlorophyll, and release excess oxygen, this process is "photosynthesis".

Respiration is carried out day and night, because photosynthesis is vigorous during the day, the carbon dioxide produced by respiration is far from enough for photosynthesis, so it is necessary to absorb a large amount of carbon dioxide from the air in order to promote photosynthesis to proceed normally. At night, photosynthesis stops completely, and plants, like humans, inhale only oxygen from the air and excrete carbon dioxide.

The process by which plants oxidize organic compounds under aerobic conditions to produce CO2 and water. The chemical reaction formula (taking carbohydrates as an example) is:

c6h12o6+6o2→6co2+6h2o+2821kj

The energy produced in this process can be partially used for various life activities. When the oxygen supply of plant tissues is insufficient or anaerobic, the organic matter in it can be partially decomposed, producing a small amount of CO2 and releasing a small amount of energy. This is fermentation, sometimes referred to as anaerobic respiration.

In contrast, respiration when oxygen is sufficient** is also known as aerobic respiration. The green part of the three-carbon plant, with glycolic acid, the oxidation product of ribulose diphosphate, as a substrate under light, continues to oxidize to produce CO2, a process called photorespiration.

Although plants rely on photosynthesis to provide energy to form organic matter, the non-green part (and the green part in the dark) is through respiration, the chemical energy in the photosynthetic products is released, in the form of high-energy bonds in ATP for various physiological activities, its basic reaction is similar to that of animals and microorganisms, and electron transport and phosphorylation are also carried out on the ** chondria. It is different from higher animals in that the leaves of plants are flat and thin, there are many stomata, and the gas exchange with the atmosphere is convenient, except for swamp plants such as rice, which have aeration tissues, there are no respiratory organs such as lung gills.

The rate of respiration varies depending on the plant species, the period of development, and the physiological state. Young, vigorous tissues have a high respiration rate, and mature and aging tissues have a low respiration rate. The most significant environmental factors affecting the respiration rate are temperature, atmospheric composition, moisture, and light.

Respiration is essential for the normal life and yield formation of plants. Especially in low-lying waterlogged areas, the lack of oxygen in the soil obstructs the respiration of the root system, which affects the growth of the root system and the absorption of water and inorganic ions. Controlling the water content is often used to reduce the respiration rate of the seeds.

For fresh fruits and vegetables, the respiration rate can be reduced by using modified atmosphere storage methods that reduce O2 concentration (to 3%) and increase CO2 concentration (to 5%).

1.Carbon dioxide.

2.Oxygen. Correct answer: Carbon dioxide.

Generally, plants respirate at night, absorb nucleated oxygen, release carbon oxide, and generate energy for the plant body.

Greenery undergoes respiration both during the day and at night. The respiration activity of plants not only accompanies the whole metabolic process of life, but also the harvested plants.

The process of plant respiration is a series of complex chemical changes that inhale human oxygen and react with substances such as carbon dioxide body sugar to produce carbon dioxide, and finally release energy, which provides most of the energy needed for plant growth.

1. Transpiration.

When the plant undergoes transpiration, the stomata on the leaves will open, which will speed up the evaporation of water and heat, which can reduce the temperature around the plant and avoid burning the leaves at higher temperatures. It also promotes photosynthesis and respiration, ensuring that the roots can absorb sufficient water and the stems can transport nutrients to the top of the plant.

2. Photosynthesis.

Photosynthesis is the basic guarantee to maintain the normal growth of plants, using the light energy brought by sunlight to convert carbon dioxide and water into nutrients such as organic matter and glucose, and at the same time, it will also release a large amount of oxygen, which is of great help to air purification. Therefore, most plants need to receive sufficient sunlight during the cultivation process.

Photosynthesis can be divided into light reactions and dark reactions. The photoreaction is the first stage of photosynthesis and only in the presence of light does the thylakoids in the chloroplast react. The dark reaction is the second stage, which can also be carried out in the absence of light, mainly in the substrate of chloroplasts, where chemical reactions occur.

3. Respiration.

Respiration is the main method by which plants obtain oxygen during the growth process. During aerobic respiration, the cavity absorbs the absolute oxygen in the air, releases carbon dioxide gas, and during anaerobic respiration, it reacts glucose with oxygen, and after decomposition, it produces lactic acid or alcohol, which is usually carried out at night.

The three major crops of <> plants are: photosynthesis, respiration and transpiration.
