Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

Cell Transportation Lab Eggs are a great example of a cell. Underneath the hard shell is a thin membrane that is just like the cell membranes in your cells. There are microscopic pores in the membrane that allow substances to move in and out of the cell. Way Cool! Recall that the function of the cell membrane is to control the internal balance of the cell. It helps to maintain homeostasis. In this lab you will use vinegar‚ an acid‚ to dissolve the shell off of the egg to expose the membrane

The Structure of Inner Ear The inner ear is the essential part of the organ of hearing‚ receiving the ultimate distribution of the auditory nerve. It also called the labyrinth. Inner ear consists of two parts: the osseous labyrinth‚ a series of cavities within the petrous part of the temporal bone‚ and the membranous labyrinth‚ a series of communicating membranous sacs and ducts‚ contained within the bony cavities. The osseous (or bony) labyrinth: Bony labyrinth is the rigid outer wall of

body‚ there are billions of cells that are essential to living – these are called nerve cells. Nerve cells‚ also known as neurons‚ “are the basic information processing structures” (Stufflebeam). There are about 100 billion of these neurons in our nervous system and are the most essential cell in it. Located in brain as well as the spinal‚ there are different types of nerve cells; including: sensory neurons‚ motor neurons‚ and interneuron (Boeree). The neuron is a cell that is structured similarly

Functions of Management There are four functions in management. These functions are: planning‚ organizing‚ leading and controlling. This paper is explains each function and how it relates to an organization. The following is an explanation taken from the book Management: Leading and Collaborating in a Competitive World‚ by Bateman and Snell‚ chapter 1‚ 2‚ 3‚ 8‚ 2009. These four functions are what management is about. The first function in management is planning. Managers must have vision

October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis‚ each daughter cell gets about

Functions of Management Jennifer Byrd August 30‚ 2010 MGT/330 Don Driscoll Functions of Management Managers in organizations are responsible for working with subordinates and resources of the organization to accomplish goals within. The functions of management consist of four different processes at different levels within the organization. Each level of management delegates duties to the lower level to ensure subordinates are accomplishing goals effectively and efficiently. The four functions

without a microscope because they are so small‚ but they are in the air‚ on our skin‚ in our bodies‚ in the ground‚ and all throughout nature. Bacteria are single-celled microorganisms. Their cell structure is unique in that they don’t have a nucleus and most bacteria have cell walls similar to plant cells. They come in all sorts of shapes including rods‚ spirals‚ and spheres. Some bacteria can "swim" around using long tails called flagella. Others just hang out or glide along. Are bacteria dangerous

ANIMAL CELL PROJECT By: Jonathan Everett Science 2nd Ms. Thompson January 11‚ 2013 Have you ever heard of an animal cell? Well‚ I you haven’t it is a cell that is found in an animal that consist of multiple organelles. Each organelle has a special job that helps the cell function. This paper will help describe each organelle in the animal cell. 1. Endoplasmic Reticulum The Endoplasmic Reticulum is found in both the plant and animal
