Scientific Discovery of Plasma. Plasma‚ the "Fourth State of Matter‚" was first identified in a Crookes tube‚ an experimental electrical discharge tube in which air is ionized by the application of a high voltage through a voltage coil‚ and it was described by Sir William Crookes‚ an English physicist‚ in 1879. It was first called "radiant matter”. However‚ Dr. Irving Langmuir‚ an American chemist and physicist‚ applied the word "Plasma" to ionized gas‚ in 1929. Plasma just happens to be the most

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic because

substances across a semipermeable membrane to gain a better understanding of how cells move materials across cell membranes. The experiment was designed to exhibit Brownian Motion; the random movement and tendency of particles of a substance to move from an area of greater concentration to lower concentration via diffusion until equilibrium has been attained. In addition to observing the passive process of diffusion‚ the experiment demonstrated how a semipermeable membrane will only allow certain substances

A Venn diagram is a drawing‚ in which circular areas represent groups of items usually sharing common properties. The drawing consists of two or more circles‚ each representing a specific group or set. This process of visualizing logical relationships was devised by John Venn (1834-1923). Each Venn diagram begins with a rectangle representing theuniversal set. Then each set of values in the problem is represented by a circle. Any values that belong to more than one set will be placed in

called peptidoglycans. Just inside the cell wall is a less rigid envelope called the plasma membrane also known as the cytoplasmic membrane. In bacterial cells the plasma membrane has two primary functions: it serves as a selective barrier to molecules that are penetrating the cell wall allowing water and oxygen to flow easily into the cell but restricting other proteins from entering; secondly‚ the plasma membrane contains enzymes proteins that cause chemical reactions to occur that are vital to the

The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid
