Because cells are the ‘basic unit of life’, the study of cells, cytology, can be considered one of the most important areas of biological research. Almost every day on the evening news, we are told about new discoveries in cell biology, such as cancer research, cloning, and embryology. ( This report provides an insight into the differences in the structure of cells and the way that they carry out their internal mechanisms. Cells form the basis of all living things and they are the smallest single unit of life. Cell biology is the study of cells and how they function, from the subcellular processes which keep them functioning, to the way that cells interact with other cells. Cell biology concerns itself with how molecules are used by the cell to survive, reproduce and carry out normal cell functions. Research today allows you to find out more about how cells normally work, and how disturbances in this normal function can result in disease. An understanding of these processes can then lead to therapies which work by targeting the abnormal function and the development in medicine is continually improving. Section 1 Cells are the smallest units of life and they can replicate independently. Their main purpose is to survive and their functions allow them to do so. All cells have common features whether they are eukaryotic or prokaryotic cells. The common features include a plasma membrane, cytoplasm, ribosomes, and DNA. A plasma membrane which is also known as a cellular membrane, surrounds all cells and its primary function is to protect them. Plasma membrane is made up of two layers of phospholipids which are a class of li... ... middle of paper ... marrow diseases, blood cancers, and immune disorders. More recently, stem cells from the blood stream called peripheral blood stem cells and umbilical cord stem cells have been used to treat some of the same blood-based diseases. One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent. Skin cells, red blood cells or gut lining cells cannot undergo mitosis. Stem cells have the potential to develop into many different cell types in the body during early life and growth. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a brain cell, a red blood cell, or a muscle cell.
