RE-Do NOW 1. A virus consists of: 3. Which of the following is smallest? preventing replication of the virus 5. What happens after the virus has been taken up by the cell? RNA or DNA & a cell membrane eukaryote cell RNA or DNA & a protein coat bacteria it begins making protein RNA and DNA & a protein coat bacteriophage it divides cell membrane protein proteins, cell membrane & RNA it inserts into the host DNA it switches to infectious mode 4. Vaccines can be used to prevent viral infection by: 2. How do viruses reproduce? creating an immune response in the host they divide by mitosis sexually- external fertilization destroying any viruses that enter the host replication outside the host creating a blocking protein on the cell inserts DNA into the host cell

Viruses A virus is a non-living particle made up of a nucleic acid and Bacteriophage Influenza Protein Coat Nucleic acid DNA RNA Viruses A virus is a non-living particle made up of a nucleic acid and either a protein or lipid-protein coat. They cause many diseases in living organisms and are useful tools for genetic research Viruses are extraordinarily small- smaller than prokaryotic cells!

Viruses Viruses do not have cytoplasm or organelles and thus cannot carry out cell functions such as metabolism They cannot grow by dividing To reproduce, viruses must enter a living cell and use that cell’s (the host cell’s) ribosomes, enzymes, ATP (energy), and other molecules to reproduce

Common viruses Influenza (the flu) Chickenpox West Nile Virus Zika Virus Ebola Hepatitis Smallpox (conquered!)

Cell Transport Read Chapter 7 sections 3 and 4. Create a concept map to organize chapter 7 section 3, in your notebook that uses the following terms: cell transport, osmosis, diffusion, active transport, passive transport, facilitated diffusion, molecular transport, bulk transport  Your concept map must show how the terms are related (similarities and differences) to each other and define them. 

Create notecards for all cellular transport methods from the concept map Front: Name of Transport type Back: Definition, Picture
