Viruses, Bacteria and Eukaryotic Cells

Fill in the blanks to make the statements correct. 1. Viruses are considered nonlivingbecause they can not perform the characteristics of life without a host2. Viruses are made of only 2 organic compounds, nucleic acids such as DNA or RNA and a capsid that is made of protein.3. A virus infects a cell by injecting DNA a cell.4. The cold, the flu and HIV are caused by a virus.5. Antibiotics are typically used to fight bacterial infections. The word antibiotic literally means againstlife. Because viruses are considered nonliving,antibiotics don’t work against viruses.6. Vaccines are used to help organisms make antibodiesto build immunity. Vaccines are made from destroyed or weakened forms of a virus. Virus Functions Unable to pass inherited traits on to offspring on their own Dependent on other organisms to replicate Incapable of undergoing biochemical reactions Unable to maintain a stable internal environment Cell Functions Ability to reproduce Can maintain homeostasis Ability to metabolize and obtain energy Capable of passing on traits by heredity 1. The virus is attaching to a host cell in stage A2. New virus particles are assembled in stage D3. Virus injecting its nucleic acid into the host cell. This is shown in stage B4. The host cell breaks open, and the new virus particles are released. This is shown in stage E5. The host DNA is destroyed and the viral genes are copied in stage C Word Bank:Lytic Infection Lysogenic Infection Lysogenic Infection Lytic Infection Use the pictures below to answer the questions below. Looking at the two above viruses (Bacteriophage and Influenza), they both have nucleic acid (DNA or RNA) and which other structure in common? capsid What is the order of the following from smallest to largest in size? bacterial cell>animal cell>virus bacterial cell>virus>animal cell virus>bacterial cell>animal cell animal cell>bacterial cell>virus What structure does viruses and bacteria have in common? nucleic acid cytoplasm cell wall capsid What structures do bacteria and animal cells have in common? Select all that apply DNA (nucleic acid) cell membrane cell wall membrane-bound organelles nucleus ribosomes What type of cells are animal cells? Prokaryotic Eukaryotic What type of cells are bacterial cells Prokaryotic Eukaryotic What bacterial cell structure is most likely used for movement? flagella Which bacterial structure protects it and provides support for the cell? cell wall What ONE structure do viruses, bacteria and animal cells have in common? nucleic acid
