How does cigarettes effect on plant’s growth?
As the time goes, the number of people who smokes got larger and larger. Every people know that smoking cigarettes are harmful for human and other organisms, but the smokers don’t decrease easily, and 1500 kids become a smoker every day. While smoking, it makes about 4000 kinds of chemicals such as tar, carbon monoxides and formaldehyde; however 43 chemicals of them are carcinogens that actually hurts people really seriously with various kinds of cancers, mostly lung cancer. Cigarettes are addictive and poisonous. Nevertheless, smoking doesn’t only affect people and animals; it also affects plants with growing.
When people smoke in front of plants, it makes many and variety chemicals at same time, and this makes a layer on plants. There are three main ways which makes plants grow up, respiration, photosynthesis, and nutrition uptake. Nevertheless, the layer made by smoking disturbs those three at the same time.
First of all, this make plants hard to do respiration. On the top of plants’ leaves, there are small pores called stomata. These are important pores that function as human’s nose. Plants need to release the oxygen and absorb new carbon dioxide again and again; however when the layer made by smoking block those pores, it cannot function properly and cause problem on the plants.
Secondly, the plant cannot do photosynthesis properly. One of the most famous sources to get energy for plants is to create nutrition with sunlight. Nevertheless, by blocking the surface of the leaves by the harmful layer, the plant cannot to get sunlight directly and it can make plants to get less sunlight. This will lead to the result that the plants cannot get enough nutrition by the sun light.
Third, this make plants hard to do nutrition uptake. Usually plants do nutrition uptake from the soil. In the soil, there are many microorganisms which can help plants to grow up; however the harmful component of cigarettes may kill bacteria in the soil and it will affect on plants. The cigarette also makes plants function hard its root properly, so it makes plants to get fewer nutrients and less oxygen.
If there is not enough oxygen, it will make the root not to grow properly. This will make the plant to be weaker, wilt and discolored. If the plants don’t get sunlight enough, it will also make the plants’ color changed. Plus, for human, the cigarette also makes the blood vessel to be thinner. Therefore, the cigarette is really harmful for the growth of cigarettes in 3 ways to get nutrition, respiration, photosynthesis, and nutrition uptake.
