Cell Essay

622 words - 3 pages

INTRODUCTION There are three main topics in the study of CELLULAR STRUCTURE AND FUNCTION which support the cell to do it activities. The first topic of cellular structure and function is the cell theory the second topic is the basic cells type. The least but not the last topic is the plasma membrane. BODY 1 The cell theory is the background of the cells discovery and who discovered it the first time. For centuries scientists had no idea that human body is consist of trillions of cells .Until an English scientist name Robert Hooke discovered the first cells in piece of cork but this cell was a dead cell Since then the study of cells began During 1600s scientist didn’t have more or enough information about cells until the first microscope was invented. Which had led the cell study to be successfully as it is also it had helped scientist to know cells in details Even though the first microscope was invented to help scientists to get to know well, scientists still didn’t know how cells functions internally until when the electronics microscope was invented which able to magnify the cell functions internally. The discovery and the improvements of the microscope had a tremendous impact on the studies of the cell. BODY 2 The basic cell types are the two types of cells. These two types of cells helps scientists differentiates the type of cell on the microscope by genotype and phenotype the names of these cells are Eukaryotic cells and Prokaryotic cells. Eukaryotic cells are described as cells with true nucleus while Prokaryotic cell are described as cells with no nucleus. Although these cells are different there is an organelles (part) that these cells all has in common which is called plasma membrane. This organelle (Part) helps the cell stay active in all...

cell parts Essay

1386 words - 6 pages The cell is the basic structure, function and biologic unit of all organisms. Cells are the smallest unit of life that can replicate independently, Due to cell theory cells are referred to as the “building blocks of life". Cells consist of cytoplasm enclosed within the membrane, which contains many molecules like proteins and nucleic acids in the cell. Organisms can be classified as unicellular or multicellular. While the number of cells in

593 words - 2 pages Cell Phones Usage While DrivingBy Mitchell C., Fairfield, MEUsing a cell phone while driving could be considered as being just as bad as driving under the influence. A University of Utah study found motorists who talk on cell phones while driving are as impaired as drunken drivers with a blood alcohol level at the legal limit of 0.08 percent. They also found that people who are talking while driving are 19 percent slower at coming to a stop then

Cell Membrane

1161 words - 5 pages Cell MembraneIn 1665, Robert Hooke, an English scientist observed cork under a microscope and noted that it was composed of small units. He called these units cells. Later it was observed that most living things are composed of cells. This led to cell theory. Cell theory is that living things are composed of cells.A theory is a hypothesis that scientific investigations have shown to be true most of the time. A law is a hypothesis that scientific

Stem Cell

1564 words - 6 pages Stem Cell is an undifferentiated somatic cell that is capable of either division to give rise to daughter stem cells, or differentiating into any specialized cell type given the appropriate signals. Cultured stem cells are critical to the concept of therapeutic cloning. The benefits of embryonic stem cell research outweigh the moral costs because of the innumerable potential benefits it can provide to the medical community.There has been much

These rules span from kindergarten through twelfth grade and into college. In the article “The only thing to fear is one hundred and twenty characters” Kevin M. Thomas and Christy D.

Sickle Cell

897 words - 4 pages Sickle cell disease is an inherited disease where the red blood cells in the body are produced abnormally by bone marrow as crescent shaped red blood cells. Unlike normal red blood cells, sickle shaped cells are unable to deliver much oxygen to other parts of the body due to the abnormal hemoglobin. Sickle cell’s are stiff and sticky and tend to clump together between blood vessels that can cause pain, damage to the organs, and infections. If a

Cell phones

821 words - 4 pages It’s not acceptable to use cell phones in class. Actually, using cell phones has more negative effects than positive. So, why do we need to change the policy that prohibits students from using cell phones in classrooms? In my opinion, I will say no, we shouldn’t change the policy that exists now - no cell phone use, under any circumstances. As what Paul Thomas says: “Teaching is a human experience. Technology is a distraction when we need

The Cell

3218 words - 13 pages The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although

Stem Cell

1007 words - 4 pages Research on stem cells began in November of 1998 when researchers were successful in isolating the stem cells in a lab. At first a selected few scientists only realized the enormous potential of stem cell. Then, in the U.S. and other parts of the world stem cell funding and research went rampant. Australia made a huge stem cell breakthrough by discovering that stem cell are to generate themselves into other, specialized cells, in particular the

Cell Transport Essay

607 words - 3 pages Cells get things they need inside themselves by transport across their cell membrane. Three types of transport are osmosis, facilitated diffusion, and endocytosis/exocytosis.Osmosis is how cells obtain water, which is what cells are mostly made of. Osmosis is the net movement of water molecules across the cell membrane from high concentration to low concentration or with the gradient. This method doesn’t require energy. Water molecules are
