The Golgi receives new proteins and lipids from the ER, finishes them up, addresses them and sends them to their final destination. In this way, the Golgi could be the postal service of the city. Lysosomes get rid of unusable waste within the cell and recycles those materials that can be reused, making it the recycling and garbage center of the city. Mitochondria are where ATP, the main energy molecule, is made. It could be considered the city's power plant. Then we have the cell's cytoskeleton, which gives the cell its shape, strength and its ability to move. It can be looked at as the roadways and bridges of the city.

Cells do not act alone and have help from things like enzymes to complete their job. Enzymes are proteins make chemical reactions within cells occur faster ("Chemical Composition of the Body," 2005). Without enzymes, most reactions would not occur under the conditions of the temperatures and pressures compatible with life ("Chemical Composition of the Body," 2005). Respiration and photosynthesis both occur within living organisms and are different reactions, but they complement one another. Respiration occurs when there is an inhalation and an exhalation ("Chemical Composition of the Body," 2005). Photosynthesis is the process where plants, algae and photosynthetic bacteria use energy from light to synthesize organic compounds and results in the release of molecular oxygen (Whitmarsh and Govindjee, 1995). Both respiration and photosynthesis take something from the external environment, bring it into the living organism and then release it back out into the external environment.

Apoptosis Living organisms are truly fascinating not only for the ways they function within their larger environments, but also at the microscopic level in how they function in and of themselves. Ultimately, of course, these two views and understandings of organisms are wholly linked and entirely inseparable, as no organism would be able to function in the environment at large if it was not functioning properly at the microscopic level. Without
Organism Physiology Evolution of Organisms For millions of years earth has gone under tremendous changes. This rapid change in environment, landscape and temperature alters the intact system and for surviving this change, a steady modification in living organisms occurs for adaption to surrounding environment. This change is never over night nor does it occur suddenly in newborns, it takes generations to evolve a new feature or characteristic. This adaption is not only
Living System The Organization as a Living System There are many different metaphorical models that have been used to describe organizations, from ships to machines to human brains. Another perspective views organizations as equivalent to living organisms or really to any complex living system, where reactions happen both on an immediate and reactionary basis and as a matter of planning and decision making. This perspective can be especially useful when viewing organizations
living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things. Biology is a very broad field that encompasses the study of characteristics of living things. It includes
There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the functions of the body at the cellular level. Examples are digestion, the body's defense against disease, and transporting substances throughout the body. Thousands of proteins
Organismic-holistic: The plant makes the cells, not the other way around. or, an organism must be seen as more than just the sum of its parts. This organism seeks environments somewhere between overload and understimulation. Sociopetal and sociofugal: Two kinds of space defined by Osmond 1957, to describe environments that inhibit or encourage conversation. (environmental cause of behavior). Sociopetal (high ceilings, large volume, high lighting) led to less conversation. Sociofugal (low
