Cell is important because it is the building block of the body. It is a replicating organism that has proteins and cytoplasm and nucleic acids inside a membrane Alberts (2002). Cells are in everything from humans to plants, though each representation of life has its own particular cells. Cells are very small and impossible to see with a microscopic lens. That is why the cell was not actually noticed until such technology came along in the 17th century. Indeed, the name cell, which means small room in Latin, comes from the discoverer of the cell, who thought they looked like the small rooms that monks in the medieval era used to live in, which were called cells (Karp, 2009). Essentially, all living organisms are made up of cells and if there were no cells there would be no life. So the cell is very important.
What do cells do? That depends on its cell type. There is more than one kind of cell. First of all, there are organisms that consist of a single cell, and then there are organisms that are multicellular. These latter are complex organisms, like humans. The different cell types in a person, for example, are stem cells,...
Each of these not only looks different from the other but also has its own function. At the same time, they all have the same genetic type within the one organism. So in me, for example, every cell has my genetic type sequence and carries my gene identity card, so to speak -- they just express themselves differently in terms of what they do.
It is difficult to talk about the origins of the cell without discussing the origins of life. Some take an evolutionary view of this matter and others take a creationist view of this. How cells came into being is something that can be theorized about or conjectured about and some feel very strongly about it because what we believe about the origins of life often holds some significance for us and acts as a framework for how we look at ourselves and life.
Regardless, we can study what cells do and the different types of cells and make theories about what early cells looked like on the planet many years ago. This can be helpful to some in understanding what the first building blocks of life were like.…

Cell Metabolism Define metabolism, anabolism, and catabolism in full details The cell is a complex organisms in which many chemical reaction take place so as to maintain normal cellular function. Cell metabolism can be defined as the process through which cells manufacture ATP which provides energy to the cells. Cells have evolved to form highly efficient metabolic mechanisms which differ depending on the cell. Aerobic respiration is responsible for cellular energy needs
Enzymes 1. How does temperature affect enzyme function? Every enzyme demonstrates maximum activity at a particular temperature known as its optimum temperature. Generally, all enzymes are inactivated at temperatures below 10°C and get denatured (lose its three-dimensional protein nature) above its optimum temperature (Seager & Slabaugh 2010). Experiments conclude that enzyme activity increases by almost ten percent coupled to each degree rise in temperature until it reaches its optimum state and declines beyond
Cell Phone and the Brain Cell phone usage has become part of daily life for many Americans. As with any new technology, health risks associated with cell phones are not always apparent and take time to surface. As popularity of this technology increases, so does the research surrounding this topic. One concern leading to an increase in research surrounding this topic is the amount of radiation emitted by a mobile device.
"The initial response to acute inflammation includes a rapid drop in numbers of circulating eosinophils, a rapid accumulation of eosinophils at the periphery of the inflammation site and an inhibition of egress of eosinophils from the bone marrow" (Bass, 1976, p.870). Basophils- Basophils are one of the least common granulocytes and they make their appearance during certain inflammation, especially those that deal will allergies. They have two main functions during
In 2002, researchers partnered with the cell phone industry to conduct significant scientific studies on the health risks of cell phones. The FDA supported many studies in response to public concerns that radiation from cell phones may pose health risks. The contract between the FDA and the Cellular Telecommunications Industry Association (CTIA) allows the FDA to select scientists and oversee the projects, while the CTIA provides funding. Both entities
