    The Effects of Temperature on Cellular Membranes Kean University: Biology 1300 Section 3 Liyet Iran Partners: Paoline Medina, Jennifer Yuen, Christian Gonzalez, D’wan McCrary, Nicole Piscatelli November 12, 2015 Abstract The cell membrane is an essential structure of any cell. It’s the structure that protects and support the cell. To determine whether this structure can withstand hot or cold environment, a beet specimen is put to test. Six consistent cylindrical beet will each be placed into different temperatures ranging from -5℃ to 70℃. When a beet cell has been damage, betacyanin, will leak out of the cell to turn the water that surrounds it red. A beet cell will exhibit some damages to their cell…

  • Functions, Role, And Structure Of A Cell Membrane

    up of cells. “Cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful.” (“Cells are the Starting Point,” 2016) There are two types of cells called eukaryotic and prokaryotic. In order for the cell to survive, it requires environmental materials to create metabolism and to dispose of waste products within the cell. “All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given…

  • The Four Components Of Cell Membrane

    that the cell is the basic unit of life. The cell provides structure for the body, takes in nutrients from food, convert those nutrients to energy and carries out specialized functions. The cell is composed of many parts, all with different functions. The cell is made up of two major parts which include the nucleus and the cytoplasm. The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is a bilayer membrane that encloses the contents of…

  • Factors Affecting The Permeability Of A Cell Membrane

    Introduction The cell membrane provides a boundary between the intracellular environment and the extracellular environment. The membrane is selectively permeable only allowing some substances to pass through while some can’t. The cell membrane consists of two phospholipid bilayers. Each layer has an electrically charged, hydrophilic head, while the tail is an uncharged hydrophobic. The electrically charged head of these layers face toward the water as the uncharged tails face each other. This…

  • The Cell Membrane: The Most Important Parts Of The Cell

    The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

  • Cell Membrane: The Two Main Components Of Cells

    INTRODUCTION TO THE CELL The cell is defined as the smallest unit of life. It is originated from a Latin word cella meaning ‘small room’ a word used by Hooke (in the year 1665 while observing a cell with the microscope he built by himself) to describe the cells. The cell is considered as a living thing because it has the ability to metabolize, grow and reproduce. Before the invention of microscope, it was difficult to talk about cells as they were tiny and so not visible with the naked eyes but…

  • Pyrimidines: The Basic Structure Of DNA And RNA

DNA and RNA are found in the nuclei of all cells and their job is to transmit the information needed for cellular growth and reproduction (Averill & Eldredge, 2007). 2. The number of carbons and the branching determines the boiling point, where the higher of either increases the boiling point. The reason behind this is hydrogen bonding (Clark, 2003). In ethanol there is an -OH group present. The oxygen pulls…

  • The Phospholipids: The Plasma Membrane

    The plasma membrane also known as the cell membrane is found in every cell. The cell membrane is around 7-10nm, making it difficult to view even with a transmission scanning electron microscope (it only shows a double black line), this means that no one knows exactly what the membrane looks like. All membranes have the same basic structure made up from phospholipids (fats). The membrane is made up of a phospholipid bilayer; consisting of a polar phosphate head and two fatty acid tails. The head…

  • Serratia Marcescens Research Paper

    or without molecular oxygen3. Serratia Marcescens is a gram negative bacterium. Gram negative bacteria have a thin cell of a single layer of peptidoglycan that is enclosed by an outer membrane. The outer membrane is surrounded by special phospholipids composed of fatty acids called lipopolysaccharides that are attached to a glucosamine…

  • Viral Pathogens Essay

    Viral pathogens use liver cells to replicate, then attach to their lipid droplets to to accumulate, assemble and bud off into the rest of the body. Liver produces and secretes LDL, VLDL and HDL which are taken up by every cell in the body that uses cholesterol, including the liver cells that take them up too.2 Viruses hijack these lipoproteins and use them to get into the liver cells, where they replicate, which opens up a gateway to the rest of the body. They replicate within the endoplasmic…
