Breath of plants
Breathing is one of the bases in the process of metabolism in plants, which ensures the exchange of air oxygen and carbon dioxide by tissues.
The air that surrounds us, and therefore plants, consists of 4/5 nitrogen and about 1/5 oxygen. In addition to these gases, the air contains water vapor and dust. Sometimes the air can contain gases that are harmful to both humans and plants, for example, sulfur dioxide, etc.
Plants are 45% carbon (based on dry mass), and carbon dioxide from the air and, to a small extent, carbon dioxide from the soil serve as a source of carbon in plant tissues. Plants assimilate carbon dioxide during photosynthesis, thus creating complex organic substances (carbohydrates, proteins, fats, etc.), from which the plant builds its tissues and organs. The process of photosynthesis takes place in plant tissues only during the daytime. Moreover, photosynthesis occurs more in the leaves of plants.
Oxygen is essential for plants to breathe. In the process of respiration, organic substances created during photosynthesis break down. Plant respiration occurs constantly, regardless of the time of day. Breathing produces carbon dioxide, water, and some energy. The respiration process is characteristic of all parts of plants, however, to varying degrees. For example, flowers breathe more than leaves, and leaves more than stems.
The processes of photosynthesis and respiration largely depend on the intensity of illumination. With sufficiently good lighting, the process of photosynthesis prevails over respiration, and the plant grows and develops well. With a decrease in illumination, the process of respiration prevails over the process of photosynthesis, while it is accompanied by the loss of organic matter. This often happens in winter, when the plant does not have enough light, it grows poorly or does not grow at all. If the leaves become smaller and stretched, they say that the plant is "starving". At the same time, root dressing will not bring anything but harm, since (as mentioned above) carbon dioxide must be absorbed by the leaves. Therefore, the plants are simply rearranged closer to the light.
Air in apartments
As a rule, almost all indoor plants relate well to the flow of fresh air, despite the fact that the green leaves themselves produce oxygen. For cacti, for example, regular airing, mainly in summer, is the key to success in keeping them. Plants can react very sensitively to harmful vapors released during painting.
Plants should not be placed in the immediate vicinity of the stove in the kitchen, as hot steam from a boiling kettle or saucepan can enter the plant. And in general, the air in the kitchen is much drier and dirtier than in the room.
Almost all plants are afraid of cold drafts, especially with a sharp temperature drop. In this case, we mean drafts during the cold season. Sometimes in the literature, plants are mentioned that can tolerate drafts, however, if the plant grows all the time in a warm room, it simply gets used to such content and even the most unpretentious plant can be harmed from the draft. Of course, a few minutes of airing the room may not harm the plants, but if a plant stands for several hours at an open window in cold windy weather, you should not be surprised that even the most undemanding of plants will drop not only buds, but also leaves.
But at home, not only the composition of the air (the proportion of oxygen and impurities) is important, but also its movement. This becomes especially important when the air humidity is high. Lack of oxygen and strong air currents leads to the development of harmful microorganisms, mold. Remember that not only plants, but also people are harmed from stagnant stale air in an apartment.
Fresh air in summer
There are plants that for the summer are better to be taken out to the balcony or planted in open ground, so that with the onset of cold weather they can be transplanted into a pot and returned to the room. These lovers of fresh air include: acacia, pomegranate, jasmine, laurel, balsam (Vanka wet), passionflower, citrus fruits, yucca and many others. When transferring plants to fresh air, it should be borne in mind that they must get used not only to lighting, but also to wind, daily temperature changes, and rain. When you return your plants to their homes in the cold fall, be sure to check them for random pests. After all, you can bring slugs, earwigs, millipedes and other very unpleasant insects and arthropods from the garden.
