The Main Features of Photosynthesis Essay

PhotosynthesisPhotosynthesis means "putting together with light." This takes place in chloroplasts, which have chlorophyll in them. Chlorophyll absorbs the sunlight. From sunlight, green plants combine carbon dioxide and water to make sugar and oxygen. Green plants use sugar to make starch, fats and proteins. These are tiny pores called stomata. Stomata are plant spores, which enable gas exchanges to take, place, and water to vapor to be lost. This has the benefit of moving water up the plane in a process called transpiration. The pore and the guard cells make up a single stoma. There may be as many as 6 million per typical leaf. The area just inside the internal structure of the leaf and below the stoma is the air space, which brings carbon dioxide very close to the palisade parenchyma tissue. Oxygen and carbon dioxide enter and leave through the stomata. Plants also sleep at night by closing their stomata. They cannot make food at this time. When green plants absorb solar energy, they convert it to chemical energy. This chemical energy aids in the growth and functions of the plant. When an organism eats the plant, it gets energy to carry out its processes. Without solar energy, plants could not grow, and life on earth would cease to exist. Chlorophyll, found in plants, is used to trap solar energy. This solar energy is import for the separation of H atoms from H2O. When water splits, H2 is released and built into ATP and NADPH2. O2 is given off, as well, which aids in the respiration of living organisms. The ATP and NADPH2 produced in the light phase is ready to be used for the reduction of CO2 to form glucose in the dark phase. The chemical equation for photosynthesis in green plants light 6CO2 12H2O C6H12O6 6O2 6H20 Currently, fossil fuels are our main source of useable energy on earth, but they are rapidly being depleted and...

Character Analysis of Basil Hallward in The Picture of Dorian Gray, a Novel by Oscar Wilde Essay

The main character in The Picture of Dorian Gray, Dorian, is a man too easily influenced by his surroundings. He is quoted as saying, Basil Hallward is what I think I am Lord Henry is what the world thinks me Dorian is what I would like to bein other ages, perhaps (Wilde). This comparison falls in line with the moral of the story because Dorian is stuck with eternal youth and beauty even though he has a wicked soul. This causes different views of him by people who observe his daily life. Dorian is a sponge throughout the novel that absorbs everything and allows it to shape his personality, morals, and actions. Dorian Gray takes influence from Lord Henry, Basil Hallward, and the culture of society during which the novel was written. Lord Henry is the epitome of a wealthy, hedonistic gentleman seeking only pleasure, with little regard to cost or consequence. Lord Henry Wotton outwardly propounds hedonism, but it is his extreme egotism that drives him to manipulate both Basil Hallward a

An Analysis of the Character of Chichikov in the Poem, Dead Souls by Nikolai Gogol Essay

Dead Souls takes place in the Russia of the late 1800s, where, unlike in America, one must be born into a prosperous family in order to have opportunities. The main character, Chichikov, is clever enough to develop a scheme in which he can rise from being a petty clerk to a respected landowner. In order to do this, Chichikov moves into a new town, pretending to already be a landowner, and begins a quest to buy the names of dead serfs who have not yet been officially reported dead. Each person that Chichkov presents this offer to has a different reaction, starting with the shy and introverted Manilov. Though he does not understand Chichikov's need for the names of these dead serfs, Manilov is a character that is so desperate for company that it does not take any effort to trick him into selling his dead souls cheaply. However, as Chichikov continues his journey, he starts to deal with more clever landowners who become suspicious of his scheme. Chichikov finds that the townsmen know
