The Cigarette smoke affect the growth of plants because a cigarettes contain many potential deadly chemicals including arsenic benzopyrene, ammonia, butane, turpentine and methoprene carbon monoxide, formaldehyde, hydrogen cyanide, lead and sulfur compounds and nicotine. These chemicals are absorbed through the stoma, an opening that opens and closes to let in water and food. This Chemicals found in cigarette smoke have the potential to alter plant DNA causing mutations. This action reduces the plants ability to absorb light, which in turn reduces photosynthesis, and then reduces the energy received from sunlight to create sugar for plant growth. Stomata pores are also caused by particulates and result in less oxygen to the plant. Tobacco Mosaic Virus that only survives in dried plant it is found mostly in the smokers house. Another effect of cigarettes smoke on plants is leaf loss, Plants suffer a condition called epinasty that results in the leaves falling off or turning downward. because the amount of ethylene in cigarette. If a lot of smoke dust builds up on the leaves, the stomata can get clogged and make the plant's respiration less effective. Another part of plant respiration is absorbing carbon dioxide and releasing oxygen. When the leaves and stem are covered in cigarette smoke dust, they cannot release oxygen properly, preventing them from absorbing new carbon dioxide.
The absorption of carbon dioxide, present in cigarette smoke benefits plants that use it during photosynthesis and release oxygen into the environment in its place. At the same time, smoke clouds the air surrounding the plant and coats the leaves, resulting in reduced available light to the plant. This results in a drained, pale color on leaves and flowers. Photosynthesis is the process plants use to create nutrients from light. Plants absorb light through the surface of their leaves. If the leaves are covered with a layer of cigarette smoke, the...
