Respiration in the leaves of plants occurs... the Process of gas exchange

The Breath – it is an integral part in the life of every living being. Oxygen is needed by all - both fish and people and animals. Why would fish need air, because she lives under water? Water is saturated with oxygen, which is needed, and underwater creatures. Now we will talk about how breathing in the leaves of plants occurs. It is important to know that in the process of plant respiration involves not only the leaves but also stems, and roots. All this you will learn from our article.

Respiration in the leaves of plants going through photosynthesis. Distinction of plants from other living things lies in the fact that the trees absorb the waste of oxygen that is carbon dioxide and in return give us what we need. Proceed to a more detailed consideration of this issue.

Breath

Respiration in the leaves of plants occurs around the clock, seven days a week. In this case, the plant absorbs oxygen from the atmosphere, but can still be used and the product of their work, that is, the oxygen formed by photosynthesis (which is needed for breathing of humans and other living beings). The product of photosynthesis accumulates in the intercellular spaces, it is necessary for breathing during the night.

The breath of night differs from day? You should breathe all day and night. Atmospheric oxygen in the daytime actively enters through the stomata, stems, roots, stem. But what to do in the dark, when stomata of the leaves in most of the cases are closed? Here comes to the aid of the stock harvested in the daytime, which is located in the intercellular spaces. From there, the product of photosynthesis reaches all the cells of a plant providing. So you should remember that respiration in the leaves of plants always happens, only the process may be slightly different in light and dark time of the day.

Keep in mind that the process of respiration and photosynthesis – this is completely opposite processes. During respiration, plants absorb oxygen, but it requires much less than reproduces the same plant in photosynthesis. It is quite a complex process, which people absorb guided oxygen oxidizes (turns) complex substances of plants in two components:

• Water;
• Carbon dioxide.

What kind Of complex substances in question? First of all, it concerns the glucose. The process of respiration releases lots of energy that has been expended on photosynthesis. During this process, as we mentioned earlier, is also formed carbon dioxide, retreating through:

• Stomas;
• Lenticels;
• Roots.

There is a lot of evidence that carbon dioxide is actually produced by the plants, but in very small quantities.

Gas exchange

So, breathing in the leaves of plants occurs in the cells of the organs located on the surface, but these cells are on the surface of the stem, roots and so on. But it is important to know that the primary circulation of gas occurs through the leaves of the plant. During photosynthesis carbon dioxide enters through the gap in ulichnyh cells, then goes into hlorofillsoderžaŝih tissues. The formation of oxygen, which is able to come to the surface, in the environment. And in the process of breathing is the opposite, the plant consumes oxygen, and the surface releases carbon dioxide.

But it is important to know that in the process of photosynthesis creates a very large amount of oxygen, which is enough not only for plant respiration, but also for the enrichment of the environment. As we have seen, these processes have opposing but strongly interrelated. Green plants are able to supply all life on earth required oxygen.

In Addition to oxygen, plants release water vapor that go also through the stomata. This process is called transpiration. All the process of gas exchange can be regulated by closing or opening ustichnoe the cracks.

Aerobic respiration

Now we need to clarify that the breath of leaf and completely plants can be divided into two phases: aerobic and anaerobic. A little bit about the first type. Aerobic respiration occurs in the oxidation process. As you know, during oxidation occurs waste of oxygen. This process can be divided into two stages:

• Oxygen-free;
• Oxygen.

In the first stage, the liberation of hydrogen by splitting of the substrate. In the second stage is the further removal of atoms.

Anaerobic respiration

The Respiration of a plant leaf takes place, as we have said, in two stages. Now a few words to say about anaerobic respiration. Which is the process of oxidation of molecular hydrogen. As a result of this biochemical process releases energy, which is the supply for ATP synthesis.
