When plants are exposed to excessive amounts of Carbon Dioxide, the plants induce the generation of Reactive Oxygen Species and oxidative stress in plants. Nitric Oxide could alleviate oxidative stress by scavenging ROS and/or regulating the Antioxidant System. Negative feedback of photosynthesis could take place in augmented CO2 as a result of an overload of chemical and reactive generated substrates, leading to an imbalance in the source carbon ratio. Long-term effects of this are floods, droughts, and increased heat/ temperature. Also, in an atmosphere with high carbon dioxide, the pores on plants don’t open as wide, so plants are not able to keep cool. This could make the plants become crispy and dry out, causing the plants to die. During photosynthesis, plants absorb carbon dioxide from the air and release oxygen. Most plants are capable of removing pollutants from the environment through bioaccumulation and incorporating it in the plant’s tissues. Too much pollutants alter plant metabolism and make plants weak and vulnerable to disease or pest infestation. Some of the recognizable signs of these processes are leaf damage (yellowing, falling leaves), poor growth, root damage, and inability to photosynthesize properly (results in stunted growth and diminishing productivity). Plants depend on several environmental factors for survival, like appropriate amount of light and temperature, sources of nutrition, water, air, and physical space and preferred medium to grow (different types of soil or water). If those factors and conditions are changed, how will the plants react to it and will it be able to survive and how well will it be able to function?
