VIRUSES
Bacteriophage
• A virus is a non-living particle
Influenza
Protein Coat
Nucleic acid
DNA
RNA
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!)

DEATH BY… WATER
• Read Chapter Mystery! Pg. 189
• Watch PearsonRealize Video: Fishing for the
Right Balance
• Form a Hypothesis (IN YOUR NOTEBOOK!)
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.
