The explanation of Arabidopsis thaliana by The World Of Genetics introduces you to the actual plant of Arabidopsis thaliana. Arabidopsis thaliana is a very important plant because it has made many impacts on the science world and many research papers have been done on experiments with this plant. This plant is known as a plant that experimenters did basic research on and conducted experiments and also it helped with other areas of research in the science world. The reason behind everyone using this basic plant to use the information for other areas in biology because this plant is very easy to grow. Arabidopsis thaliana is small in size so its very easy to grow and not to hard to grow anywhere. This plant can be grown well in simple places. Also this plant can be very easily experimented on multiple times due to its 6-8 week germination. After germination, the plants must make there own food in a special process called Photosynthesis. “Arabidopsis thaliana”
Plants must make their own food after germination. This process of which they make there own food is call photosynthesis. The essential things needed for photosynthesis are sunlight/ light source, water, air and chlorophyll. This process is a base of all growth of plants. During this process of photosynthesis they take the sunlight or light source given and turn it into food for them selves to grow. This process takes place in the part of the plant called the chloroplast, that’s where chlorophyll is found. This whole process of photosynthesis is very important for everyday life. Plants need this process to live and we the humans need them to live also. That is why photosynthesis is very important to plants. But this process of photosynthesis can be disturbed when a pollutant is involved and when plants are exposed to them. A example of a pollutant that occurs very often is Heavy Metal pollution. “How plants make food” The explanation of Heavy metals poisoning by the “ World of Chemistry “ explains how metals are poisonous to plants and other things in daily life. These heavy metals can be very toxic when plants are exposed to these things. When the plant is exposed to heavy metal contamination, it disrupts the germination process, which then will result in the plants death or mutation. Heavy metals can not only be toxic and poisoning to plants, but can also effect other living organisms and humans as well. Heavy metals are very dangerous and very toxic to plants and other living organisms. “Heavy Metal Poisoning” The author (Sethy, Sunhil and Shyamasree Ghosh) conducted experiments on mechanical stress on plants germination process. Everyday with all the industrialization and mass population, many things such as heavy metal are not only harming the environment, but are also affecting animals and plants too. The heavy metal acts as a stress in the plant germination process and effects the plants progress in growing. These heavy metals will get into the soil, and soil is a very big factor in the germination of the seeds. Without soil, these plants are nothing If the Heavy metal contaminates the soil, it will poison the plant. This problem with the heavy metals releasing into the soil has become a serious problem worldwide. When plants and soil are exposed to heavy metal contamination, the whole germination process of the seed will be distressed and thrown off. A heavy metal that could harm this process would be Zinc. ( Zn ) “The effect of heavy metals on germination of seeds” The investigators in this article will experiment dysfunction under excess zinc on Arabidopsis cell expansion. Zinc is a very harmful toxin when given or when things are exposed to it in high levels. Some of the effects to the plant are short root growth, root hair, and mutative symptoms. From here, the plants cell wall reduced as well as cell expansion These are all outcomes of excessive amounts of zinc exposure. The investigators are explaining that too much zinc exposure will change / mutate the Arabidopsis plant. They conclude that excessive zinc exposure will cause changes in the plant and also will start to mutate with these changes. With all this contamination, there has to be some way to remediate, or help the cause for cleaning. “New Findings Reported From Nara Institute Of Science & Technology Describe Advances in Plant Signaling and Behavior” When plants and soil are exposed to heavy metals and contaminated, the process in which trying to clean or dis-contaminate the plants is a very long, hard process. In this article, Mich, M explains what you go through to clean and disinfect plants and the environment of heavy metal pollution. This process he is explain is called Phytoextraction. This long process has been proved that this way of cleaning plants and the environment of heavy metal pollution has been successful. To clean the plants and environment, you must start by cleaning the soil and then going from there. This process is very long, but it will be successful. After all this heavy metal contamination, there must be a way to clean up or even try to clean up. That’s why in this article, it shows a way called Phytoeextraction to clean. “ Phytoeextraction of toxic metals”
