Essay about Photosynthesis : An Open System

780 Words 4 Pages
Photosynthesis is a key contributor to the survival of humans. Earth is an open system requiring the input energy to drive life processes Photosynthesis uses light energy to produce chemical energy which is glucose. Photosynthesis deals with plant growth as well as being a source of energy and food. The four things needed for plant growth are energy in the form of solar radiation, carbon in the form of carbon dioxide, mineral nutrients and water (Kirk, 1994). In order for plants to be able to conduct photosynthesis, plants need chloroplasts. Chloroplasts, green colored cells, are a plastid that contains chlorophyll and in which photosynthesis takes place. Photosynthesis is indeed very essential for plants survival but it depends on environmental factors. For example, photosynthetic tissues can experience variations in temperature which can affect the rate and integrity of components in photosynthesis (Govindjee, 2012). Other essential resources that contribute to photosynthesis varies in habitat and time as well. In the same process, water is used and oxygen is released into the atmosphere. The oxygen released from photosynthesis is what we use to breathe and is needed for our daily lives. The oxygen being released is a part of Respiration. Respiration comprises of four different stages.
The first stage of respiration is Glycolysis and is located in the cytoplasm (cytosol) of the cell. Glycolysis breaks down the glucose that is going to be used into pyruvate. Pyruvate…
