Research Paper On The Chemistry Behind Trees

The Chemistry Behind Trees Chemistry plays a huge role in our environment. Although many individuals may be aware of the importance of chemistry, the truth is, chemistry revolves all around the world in its own way. The purpose of our existence is involved with chemistry. All living things require oxygen in order to survive; trees provide humans with that advantage. Trees are the air-purifiers of our planet. Trees also make the sugar that we consume. All this happens through the amazing process of photosynthesis. The main reason we are capable of breathing, is because of the process trees go through to release the oxygen we inhale. Photosynthesis must go through two cycles, the light reaction and the Calvin cycle before releasing oxygen and sugar. …show more content…

The Chloroplast contains green pigment called chlorophyll which absorbs light energy from the sun. That is where the first stage occurs, which is known as, the light-dependent reaction. This stage takes place in stacked thylakoids, known as the granum. The light-dependent reaction is highly dependent on light energy. The products of this stage are light, water, and carbon dioxide. The light energy splits water molecules into oxygen and hydrogen ions. Oxygen gas is released to the air as a by-product. Adenosine tri-phosphate (ATP) and nicotinamide adenine dinucleotide phosphate NADPH is released and used in the next stage, the Calvin cycle. The Calvin cycle is the process, in which trees turn carbon dioxide from air to sugar. This stage takes place inside the chloroplast as well but not in the granum. The Calvin cycle takes place in stroma. The ATP and NADPH that was released in the light-dependent reaction are now used in this stage. The NADPH contains high energy electrons. These reactions use chemical energy from NADPH and ATP, which then creates the final product, glucose. This process is known as carbon

By their very nature, they embody beauty. But they also pulse with energy and resilience. Tough and resourceful, they battle difficult odds and often win. By a long shot, they outlast humans” (Richard Powers, Gale Literature). Even though trees are living things just like humans, they’re treated differently because of the lack of life

Trees can produce different products that can be used for building and other day-to-day functions. In the text “tree Cutting Does Have Positive Environmental Consequences,” Bill Cook, a forester and wildlife biologist, describes that the construction of buildings would be impossible without cutting the trees for wood (Cook). For example, when building a house, construction workers first make the structure of the house from wood, before adding cement and any other building essentials. Paper products, such as toilet paper and boxes, are made from different parts of trees (Cook). The deforested trees are not being wasted because other parts of the tree will be used when necessary.

One of the most recognizable importances of trees is that, trees provide an ample amount of oxygen. Trees provide much more benefits than just this. Trees can help prevent soil erosion, by slowing runoff and holding soil in place. Another way trees help the environment is that trees can help prevent water pollution. According to treepeople.org they do this by reducing runoff, which in turn allows the water flow down the trunk of the tree into the ground.

Carbon from the atmosphere is absorbed into plants during photosynthesis and when the plant decays or is burnt that carbon goes back into the atmosphere. Because it is a cycle, the next crop of plants absorb that carbon over again, so this process does not contribute much to the release of carbon dioxide into the atmosphere. 3.2 Cons of Biomass Energy 3.2.1 Requires Space Big areas are required for all the different processes that is required in harnessing energy from biomass.

For example, trees have a complex symbiotic relationship with soil borne fungi through their roots which connects them to other trees in a forest, even competing species. They can actively choose to share nutrients to other trees, specifically direct family members, synchronizing their performance so that they are equally successful. There’s more connecting trees to each other than just fungal root systems, trees have also been proven to have a sense of taste. Compared to the slow transmission of signals inside a tree, trees can send airborne chemical alarm calls to the surrounding forest. For example, upon an insect infestation this allows trees to send a warning for other trees to fill their leaves and barks with a bitter compound that deters insects before the insects can ever arrive.

They provide massive amounts of oxygen and store carbon dioxide. Every second one and a half acres of forest is being cut down. The rate of deforestation per minute is equal to the same amount as 19 football fields, if this rate continues there are not going to be any forests within 100 years. This is a rapid amount and is expected to increase. Many rain forests have already been cleared.

The argument of global warming is a debatable and polarizing subject which divides the people of the world into two camps: those who believe it and those who do not. It’s the similar situation for the idea of planting trees to save the planet. There was a controversial article “To Save the Planet, Don’t Plant Trees” by Nadine Unger which is published in The New York Times , she claimed that it’s bad for our planet to plant more trees, since the trees would absorb more sun’s energy and raise the planet’s surface which will cause more global warming and emit reactive volatile gases which are bad for human. What’s more, it’s not effective to plant trees to control the climate, thus we can’t save our planet by planting more trees. Actually, the

In forests the soil is very moist, or wet, without the protection of tree-cover, the sun dries up all the terrain. Trees return water vapor in the atmosphere, thus helping to perpetuate the water cycle. The roles of trees are crucial to maintain a suitable environment for ecosystems that are inhabited in that precise area. The lush forests will quickly turn into uninhabited, barren, land. This disruption leads to more extreme temperature swings that can be harmful to biotic factors.

The top two inches of the acidic soil contains 99% of the nutrients. Nine tenths of the forest's energy is stored in the leaves and tissues of the trees themselves. The forest floor is a porous mass that prevents minerals and nutrients from being washed away and lost. As soon as a tree falls, or a creature dies, decomposers begin to turn it into a food source and mulch. The vegetation to renew the cycle quickly absorbs the nutrients that are released.

The plants of the rainforest turns carbon dioxide into H2O(oxygen) which is vital to both human and the inhabits of the rainforest. Most of the animals depend on each other to survive in the rainforest. The biodiversity of the rainforest ensures natural sustainability for all life forms. The importance of the rainforest to humans, it serves as a protectant to the nutrients in the soil the trees and plants maintain the soil quality.

They also help water move from the soil to the atmosphere through a process called transpiration. Plants not only supply us with food, but with other provisions such as wood products, fibers, oils, resins, coal, and petroleum. They also provide us with raw material needed to make shelter, clothing, medicines, and fuels. It’s also a fact that one quarter of the medicines we use are derived from plants; and that 4 out of 5 people in this world rely on plants for primary health care. Importance of Plants Plants are everywhere.
