Biology 104 Chapter 3 Cell Structure and Function 0 An is a chemical or substance that can slow or even stop the growth of bacteria produced by living organisms Example Penicillin treats pneumonia syphilis gonorrhea and meningitis 0 Formation of Penicillin 1 A single 2 Nutrients on the 3 Cell division bacterial cell I plate support the occurs and lands on a growthdivision of now the mold culture plate the cells is visible 0 Antibiotics kill bacteria because they target What s unique about bacteria cells 0 The concept that any living thing is made from cells and that those cells are made by reproduction of other cells cells come in all shapessizes o are cells Without internal membranebound organelles smaller simple internally o are cells that contain membrane bound organelles membranes internally compartments delineate functions YOU are EUkaryotic o are membranebound compartments of eukaryotic cells that have specific functions 1 Cell membrane on the outside made of phospholipids 2 Cytoplasm 3 Ribosomes Prokaryotic and Eukaryotic are different in structure 4 Have DNA 0 Parts of a Cell a phospholipid bilayer with embedded proteins that forms the boundary of all cells a complex of RNA and proteins that carries out protein synthesis in all cells the gelatinous aqueous interior of all cells a complex of RNA and proteins that carries out protein synthesis in all cells the organelle in eukaryotic cells that contains the engetic material NOT in prokaryotic cells a ridged structure enclosing the cell membrane of some cells that attributes to keeping its shape the structure allows bacteria to survive in watery environments such as blood intestines or pond water is the diffusion of water through a semipermeable membrane from an area of low to high concentration means that a solution has a low concentration means a solution has a high concentration Hypertonic 9 Hyper high energy means that the same solution concentration of the surrounding cell is a polymer made of sugars and amino acids that link to form a chainlike sheath around the cell only bacteria refers to bacteria with a cell wall that includes a thick layer of peptidoglycan that retains the Gram Scale refers to bacteria with a cell wall that includes a thin layer of peptidoglycan surrounded by an outer lipid membrane that does not retain the Gram Scale are split into two categories and the tail cluster together away from water 9 hence the phobic part is the movement of small hydrophobic molecules across a membrane of high to low concentration does not require an input of energy are proteins involved in the movement of molecules across the cell membrane cells of the body contain hundreds of different transport proteins is movement of large hydrophilic solutes moving across a high to low concentration with the help of transport proteins energy input not required is the energy requiring process by which solutes are pumped from low to high concentration with the help of transport proteins is the double membrane surrounding the nucleus of a eukaryotic cells More parts of a cell membrane bound organelles responsible a network of membranes in eukaryotic cells where proteins and lipids are synthesized an organelle made up of stacked membrane enclosed discs that packages proteins and prepares them for transportation an organelle in plant and algal cells that is the site of photosynthesis an organelle in eukaryotic cells filled with enzymes that can degrade womout cellular structures a network of protein fibers in eukaryotic cells that provides structure and facilitates cell movements o is the scientific theory that freeliving prokaryotic cells engulfed other freeliving prokaryotic cells billions of years ago forming eukaryotic organelles such as mitochondria and chloroplasts Basically cannibalism for prokaryotic cells but instead of the cells being Vicious and just engulfing other cells they made a positive With a new organelles References Works Cited Shuster Michele Janet Vigna Matthew Tontonoz and Gunj an SinhaBiology for a Changing World with Physiology New York City WH Freeman 2014 Print
