The Process of Photosynthesis

“Sunlight plays a much larger role in our sustenance than we may expect all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems” (Vermaas). This quote shows that photosynthesis is the most essential part of the exchange between humans and plants because it produces all the resources we need. When we sit down to eat fruit or vegetables, we usually don’t think about where those come from, how those grow up. Or we might know plants rely on water and light to grow up, and they are able to process photosynthesis. Photosynthesis seems like familiar to everybody, but its function isn’t understood by everyone. In order for us to understand the process of photosynthesis, we need to learn what procedures the plants do during photosynthesis in process.
In order for us to understand how photosynthesis works, we must know about the absorption of basic requirements. First of all, plants’ leaves absorb light and carbon dioxide in the meantime. In the words of a researcher, “The initial step in photosynthesis is the absorption of light by chlorophylls attached to proteins in the thylakoid membranes. Like cytochromes, chlorophylls consist of a porphyrin ring attached to a long hydrocarbon side chain” (Lodish, Berk, and Zipursky). The main function of them is to absorb energy and transfer it to the reaction center for further photosynthesis reactions. Chlorophylls are what make plants look green because there are some pigments which reflect green light inside. They include accessory pigments that are able to absorb light but not green light. Chlorophyll a is able to absorb light in violet-blue region...

...ificant in order to realize how plants help our earth keep spinning. Green plants are the lung of mother earth .Photosynthesis is the only way that continues plants life, and plant is the only way that continues humans’ lives. Human need to breathe, we need oxygen in the air to keep our hearts beating. Plant is the only creature responsible for providing oxygen, which is needed by every creature in the world to breathe. Plants produce oxygen and reduce carbon dioxide for our lives every day through photosynthesis. As carbon dioxide content reducing, it resists the pace of climate change being to fast. They play an important role as food in the world; we need fruit and vegetables to maintain our lives. That’s why we must understand how photosynthesis works. As we understand how important photosynthesis is, we know the significance of protecting plants from destroying.
