Viruses Vs. Cells Comparing the two.

Quickwrite!  Based on what you remember about viruses and cells from IPC: Differences between the two? Similarities? Examples of each? Be prepared to share.

QuickShare! Discuss what you wrote with your table partner.

Set up you notes as cornell notes Set up you notes as cornell notes. You are expected to write 3 questions that you may still have or need more understanding on in the left margin and provide a summary at the bottom. I will check tomorrow.

Create a Venn diagram comparing and contrasting virus/cells

Structure: Viruses: Cells: Central core of DNA or RNA surrounded by a protein coat Cell Membrane & cytoplasm Eukaryotes will have a nucleus and organelles

Size: Viruses: Cells: TINY! 5 – 300 nanometers Larger: 1 - 100 micrometers 1 meter = 1000 millimeters (mm) 1 millimeter = 1000 micrometers (µm) 1 micrometer = 1000 nanometers (nm)

Reproduction: Viruses: Cells: Dependent on host cell Independent Reproduction Asexual Sexual

Genetic COde: Viruses: Cells: DNA or RNA DNA only

Viruses continuously reproduce, but NEVER grow. Growth & development: Viruses: Cells: No Yes In multicellular organisms, cells increase in number and differentiate Viruses continuously reproduce, but NEVER grow.

Obtain Energy: Viruses: Cells: No Yes Viruses use their hosts’ energy. Therefore, when the host is too weak to produce energy for the virus, the virus moves on.

Respond to the Environment : Viruses: Cells: No Yes

Change over time: Viruses: Cells: Yes Yes

Examples: Viruses: Cells:

How to Stop: Viruses: Cells: Vaccines Antibiotics

QUICKWRITE!  CHOOSE ONE! (or two or three if you have the time) How has your knowledge of viruses and cells changed? What was most interesting? What applies to everyday life?
