Do plants need to absorb oxygen from the outside?

When the light reaches a certain intensity during the day, photosynthesis is greater than respiration, and there is no need to absorb oxygen; At night or when the light is low, respiration is greater than photosynthesis, and plants need to absorb oxygen from the outside.

1. Plants: Plants are one of the main forms of life, including familiar organisms such as trees, shrubs, rattans, grasses, ferns, green algae, lichens and so on. It is estimated that about 350,000 species of seed plants, bryophytes, ferns and ferns exist.

Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity and light are the basic needs of plants for survival. Seed plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds.

Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalytic operation of enzymes, the use of water, inorganic salts and carbon dioxide for photosynthesis, the release of oxygen, the production of glucose and other organic matter, for the use of plants.

2. Definition: In nature, all living organisms belong to living organisms. Organisms should be divided into several kingdoms, and the sedentary and autotrophic organisms are called the plant kingdom, referred to as plants.

3. Components:

Plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds.

4. Function: Most of the solid substances of plants are obtained from the atmosphere. Through a process known as photosynthesis, plants use the energy from sunlight to convert carbon dioxide from the atmosphere into simple sugars.

These sugars are used as building materials and form the main structural components of plants. Plants rely on the soil for support and water, as well as important basic nutrients such as nitrogen and phosphorus. For most plants to grow successfully, they also need oxygen from the atmosphere (for respiration) and oxygen around their roots.

However, some special vascular plants, such as mangroves, allow their roots to grow in a hypoxic environment.

Yes, because the activities of plants are carried out by obtaining energy through respiration, including photosynthesis. Most respiration requires the use of oxygen.

Plants will absorb oxygen, plant respiration and human respiration need the same oxygen, during the day green plants photosynthesize, release oxygen, at night when there is no light, plants will respire to absorb oxygen, release carbon dioxide, but some plants can also release oxygen at night, such as tiger pill orchid, white palm, spider plant, ivy and gerbera, etc.

Plants will absorb oxygen, plant respiration and human respiration need the same oxygen, green plants carry out photosynthesis during the day, the generation of oxygen is greater than respiration, at night there is no sunlight, plants can only respire, to absorb oxygen, release carbon dioxide.

Most plants release carbon dioxide at night, but some plants can release oxygen at night, such as tiger pill orchid, white palm, spider plant, ivy and gerbera, etc., which can be cultivated at home, which can effectively purify the air and promote human health.

The leaves of the plant can carry out photosynthesis, absorb harmful gases in the air, release oxygen, have the effect of purifying the air and improving air quality, and the plant also has the effect of beautifying the environment, adding a touch of color to the city scenery, especially the garden plants, which have high ornamental value.

Plants have six major organs, namely roots, stems, leaves, flowers, fruits and seeds, among which roots, stems and leaves are the vegetative organs of plants, and the fruits contain many seeds, and the seeds are formed after fertilization of the ovules of seed plants, which are composed of seed coats, embryos and endosperms.

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.

Absorbs more carbon dioxide.

The process by which green plants use the sun's light energy to assimilate carbon dioxide (CO2) and water (H2O) to make organic matter and release oxygen is called photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates and releases energy.

In 1990, a fossilized red algae, the first known sexually reproducing species on Earth, was discovered in the Canadian Arctic, and is believed to be the oldest ancestor of modern plants and animals ever discovered. There was no consensus on the age of the red algae fossils, with most agreeing that they lived about 1.2 billion years ago.

In order to determine the age of this red algae fossil, the researchers went to Baffin Island, Canada, to collect the black shale containing this red algae fossil and analyzed it with rhenium-osmium isotope dating, and believed that the red algae fossil is 100 million years old.

Based on the confirmation of the age of red algae fossils, the researchers used a mathematical model called a "molecular clock" to calculate biological evolutionary events based on the rate of genetic mutations. They concluded that about 100 million years ago, eukaryotes began to evolve chlorophyll that can perform photosynthesis.

Plants also need oxygen for respiration, but the photosynthesis of green plants during the day, that is, the production of oxygen is greater than respiration, and in general it seems to release oxygen. At night, when there is no light, only respiration is carried out, which is to absorb oxygen and release carbon dioxide. In terms of total volume, the photosynthesis of a plant is greater than that of respiration, so it still releases more oxygen than it consumes by respiration.

Photosynthesis causes plants to accumulate carbohydrates, and respiration is the consumption of carbohydrates to produce energy for the plant body.

Green plants, like us humans, also have to absorb oxygen, and plants must also carry out aerobic respiration, decompose organic matter and release energy to maintain their own metabolic consumption. Plants release a lot of oxygen during the day, just because the plants are daytime.

The intensity of photosynthesis.

greater than the intensity of breathing.

So the net output is oxygen. When there is no light at night, the plant stops photosynthesis and only absorbs oxygen, but does not release it.

The first is to make it easier for the roots of the plant to absorb oxygen, as oxygen does not easily enter without loosening the soil. Secondly, loosening soil keeps the soil in a relatively bulky state, which is also conducive to the uniform distribution and absorption of water and nutrients.

Photosynthesis is extremely complex, and chlorophyll, the carotene in chloroplasts, plays a very important role in photosynthesis. Chloroplasts are able to continuously convert and consume organic matter, water and sunlight, and the final product is the organic matter of the producer and the oxygen released. The code of life is so fascinating that I believe that one day we humans will be able to synthesize chloroplasts or alternatives to environmental the greenhouse effect.

Most plants photosynthesize during the day, absorbing carbon dioxide and releasing oxygen. Ninety-eight percent of the oxygen needed by humans comes from the photosynthesis of plants.

Plants absorb carbon dioxide to produce oxygen through photosynthesis, mainly due to the chlorophyll in the plant.

It is produced by the chemical reaction process of the photoreaction stage of the plant in photosynthesis, that is, the photolysis reaction of water carried out by 1 water molecule on the thylakoids in chloroplasts under light conditions and under the action of enzymes, produces 1 2 oxygen and 2 hydrogen ions.

Green plants produce oxygen through photosynthesis, green plants absorb carbon dioxide, which is processed in chloroplasts under the irradiation of light to produce carbon dioxide and water.

Plants produce oxygen through photosynthesis, 80% of the oxygen required by the class comes from the photosynthesis of plants, and plants do not only produce oxygen without consuming oxygen, in winter, plants have no way to photosynthesize, but to consume oxygen.

Because there are chloroplasts in the mesophyll cells of plants, photosynthesis can be carried out in chloroplasts.

Chloroplasts are the most important and ubiquitous plastids within plant cells, and they are organelles that carry out photosynthesis. Photosynthesis is usually the process by which green plants (including algae) absorb light energy and synthesize carbon dioxide and water into energetic organic matter while releasing oxygen.
