Pdf Structure Of Cell

Act as lubricants on outer surface of cell membrane. Act as receptors for extracellular components. Prevent immune system from attacking cell. Provides recognition signals to immunesystem proteins. Cell Membrane Anatomy and Physiology for Engineers Slide 320 Membrane Transport Permeability of cell membrane determines which substances enterleave cell. Essentials of Cell Biology the cellular structures responsible for cell function, the signals that cells use to communicate with one another. about the gross structure of cell mem branes. We suggest that an analogy exists between the problems of the structure of mem branes and the structure of proteins. The latter are tremendously diverse in composition, function, and detailed structure. Each kind of protein mole cule is structurally unique. Membrane Structure and Function All cells have a plasma or cell membrane, which contains the cell. Scanning electron micrograph (SEM) of adipocytes (Ad) Lab Exercise: Cells, An Introduction to Cell Structure and Function (Revised Spring, 2012) page 3 Activity 2: Diffusion Experiment Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. The movement is due to the inherent kinetic energy of the particles of the substance. 2 Cell Structure Lesson Summary Cell Organization Eukaryotic cells contain a nucleus and many specialized structures. Inside the Cell I An Owners Guide to the Cell 7 Nucleus: The Cells Brain Look down. Youre stand ing on a somewhat spherical structure about 50 feet in diameter. Its the nucleus basically the cells brain. PARTS OF THE EUKARYOTIC CELL The structures that make up a Eukaryotic cell are determined by the specific functions carried out by the cell. Thus, there is no typical Eukaryotic cell. Nevertheless, Eukaryotic cells generally have three main components: A cell membrane, a nucleus, and a variety of other organelles. Plant cell pictures Animal cell pictures Diagram of cells labeled Worksheet Process: Have students take notes on PowerPoint presentation of animal cells. Show diagrams of cells on PowerPoint and ask students to identify the pictures at end of class.
