What Goes Around Comes Around

Abstract

Photosynthesis envelopes everything we need to sustain life whether directly related or indirectly related. Biology involves a great responsibility for the safety and well-being of all inhabitants of the earth. Our daily lives and the comprehension of what it takes to keep the various life forms alive is very important (Nahle, 2004).

Photosynthesis is the process by which plants use energy created from the sunlight; producing and storing sugar (carbohydrate). The conversion of light energy to chemical energy is associated with the photosynthesis process of chlorophyll and the green pigmentation of plants (Photosynthesis, 2000).

Plant leaves are the most significant focal point of photosynthesis. There are four parts to the plants leaves. The first one is the upper and lower epidermis. The second one is the stomate. The third one is vascular bundle (which are the veins) and the mesophyll. There's no occurrence of photosynthesis in the upper and lower epidermal cells therefore they do not have chloroplast; their simply there to guard the rest of the leaf. The stomate allow gases like CO2 (Carbon Dioxide) in and discharge O2 (oxygen); this happens generally in the sub epidermis. The veins of the leaf (vascular bundle) move nourishments and water through the plant as required. A mesophyll cell which can be found in between the epidermises contains chloroplasts; photosynthesis takes place here (Photosynthesis, 2000).

The process where oxygen takes part in the breaking down of molecules then releasing electrons forming energy is called Aerobic respiration. Adenosine Triphosphate (AT) which is liable for storing and carrying out energy to additional cells is a substance created by aerobic respiration. The nourishment that animals eat eventually is broken down to its most basic form which is sugar (Black, 2010). There are three main stages of Aerobic Respiration; Glycolysis, Kreb's Cycle, and Electron transport phosphorylation (Black, 2010).

Photosynthesis and respiration both take place within plant and animal cells. Respiration and photosynthesis are linked because they both utilize carbon dioxide and oxygen. In order to provide us with energy from the food we eat photosynthesis stores energy as earlier stated and respiration releases it ("The Flow of Energy", 2008). The sustainment of life on earth as we know it would not exist without one or the other. Basically what goes around comes around; every living organism needs energy no matter how it's obtained. Everything or everyone either eats plants or eat animals that eat plants.

Photosynthesis and respiration are connected between plants and animals through two organisms called autotrophs and heterotrophs. An organism competent of manufacturing its own food is identified as an autotroph. Autotrpohs are very much a part of the photosynthesis procedure. Animals and humans that create their own food are considered heterotrophy organisms. Heterotrophs are not a part of the photosynthesis process but the organism is an important element of respiration. Since photosynthesis and respiration in one way or another deals with carbon dioxide as well as the reactant water that is how their linked (Jansen, 2010).

Energy is transmitted from sunlight to ATP from ATP to sugars and finally to human cells all through photosynthesis (The Sun Maker, 2009). A sequence of reactions in biochemistry where carbohydrates are broken down to a chemical compound called pyruvate; discharging available energy in the form of adenosine triphosphate (ATP) is known as glycolysis (A Dictionary of Biology, 2004). When energy is extracted from carbohydrates by organisms while there's no oxygen present is Fermentation (Cells & Evolution of Life, 2008). Fermentation is generally used in many ways.

A number of organisms in the nonexistence of oxygen from time to time go through a course of action described as fermentation. Fermentation permits these organisms to create energy under anaerobic conditions (Cells & Evolution of Life, 2008).

In a biological system energy comes into as light or photons. Through cellular methods including photosynthesis and respiration it is converted into chemical energy. Carbohydrates are developed throughout the infusion of carbon dioxide and hydrogen. Subsequently energy is stored in ATP (adenosine triphosphate)
