WRITE ABOUT A THEME: ORGANIZATION While virusesare considered by most scientists to be nonliving, they doshow some characteristics of life, including the correlationof structure and function. In a short essay (100–150 words),discuss how the structure of a virus correlates with its function.
The cell is the basic unit of all living things, and viruses which are generally not considered living but have the ability to infect cells.
Describe how the structure of a virus compares to the structure of a cell. You should explain (not list) at least two similarities and two differences between features of cells and viruses including a brief explanation of the function of those structures.
Explain why viruses need cells.
Students are debating about differences between viruses and cells. Which student’s argument is MOST correct using evidence from the diagrams?
A.
Diagram 1 represents a virus and Diagram 2 represents a cell because viruses do not have nucleic acids but cells do.
B.
Diagram 1 represents a cell and Diagram 2 represents a virus because a virus has nucleic acids and cells do not.
C.
Diagram 1 represents a cell and Diagram 2 represents a virus because viruses have a protein capsid while cells have a lipid membrane.
D.
Diagram 1 represents a virus and Diagram 2 represents a cell because cells have ribosomes to make their own proteins and viruses do not.
