Structure of Eukaryotic Cells and Importance of Membranes Essay Example

Structure of Eukaryotic Cells and Importance of Membranes

Most of the cell's organelles are enclosed by membranes which are simple to observe under a microscope. For example, researchers can use electron microscopy to take a high-resolution picture through a thin cross-section. The use of an electronic microscope assists researchers in visualizing the structural formation and important features of various organelles. Different characteristics such as the extensive, narrow sections of the endoplasmic reticulum or the compressed chromatin within the nucleus are easily observed under an electronic microscope (Lanza, 2009). An electronic microscope offers a perfect outline of a cell's internal structures. The light microscope has less powerful methods that projects joined organelles. However, the use of certain stains has facilitated researchers to observe organelle structure more visible. This specific stain assists in seeing clearly the several scattered organelles within the cells. Nevertheless, a cell's organelles are not stagnant because they are in continuous motion (Lanza, 2009). Occasionally these organelles are going towards a specific location within the cell and on other occasion absorbing with other organelles. At times, an organelle can develop into a bigger or lesser organelle. These lively variations in cellular structures can be detected with video microscopic methods which provide slow-motion videos of the entire organelles as the organelles move inside the cells (Lanza, 2009). The nucleus is one of the most important organelles among eukaryotic organelles. The existence of a nucleus is reflected as one of the crucial features of a eukaryotic cell. This organelle is vital because it is the location at which the cell's DNA is stored and the activity of interpreting it initiates. DNA contains vital details essential for the creation of cellular proteins. In eukaryotic cells, the membrane that encloses the nucleus also commonly knows as the nuclear divide the DNA from the cell's protein production organelles (Lanza, 2009).
