What structure is found in viruses but not in cells?

• RNA

• Proteins

• Capsid

• DNA

In the table below read the description and choose whether it is describing a cell, a virus, or both.

Groups:

(a) Cell

,

(b) Both Cell & Virus

,

(c) Virus

• Does NOT need to maintain homeostasis

• Requires a host

• Contains genetic material

• Needs energy in order to function properly

Which statement describes the role of viruses in causing a disease?

• The virus enters into the host DNA and permanently stays there so that the viral DNA can be passed on to the next generation.

• The virus attaches to specific cells and forces the cell to make new viruses before destroying the cell.

• The virus attacks all the cells it comes into contact with and causes all cells to self-destruct.

• The virus enters into the host DNA and remains there until the host cell dies.

Cells and viruses are both microscopic. Which statement most accurately describes why cells are considered living and viruses are considered non-living?

• Both cells and viruses contain lipids.

• Cells have genetic material; viruses have proteins.

• Both cells and viruses are capable of homeostasis and energy conversion.

• Cells require energy; viruses do not require energy.
