Review: Viruses and Cells, Spread and Disease

1. Comparing Structures of Viruses and Cells

• Viruses are much smaller than cells.

• Cells have many parts like a nucleus, cytoplasm, and a cell membrane, while viruses mainly have genetic material (DNA or RNA) inside a protein coat.

• Unlike cells, viruses cannot live or reproduce on their own; they need to infect a host cell.

Sentence Starters:

• "A virus is different from a cell because..."

• "Cells have ____ while viruses have ____."

• "Viruses cannot reproduce by themselves because..."

2. How Viruses Spread

• Viruses spread through contact with infected people, animals, or surfaces.

• They can be transmitted by coughing, sneezing, touching, or through bodily fluids.

• Once inside a host, the virus attaches to cells and takes over their machinery to make more viruses.

Sentence Starters:

• "Viruses spread from one host to another by..."

• "A virus enters the body when..."

• "The virus attaches to the host cell by..."

3. How Viruses Cause Disease

• Viruses cause disease by damaging or killing the cells they infect.

• The infection can trigger the immune system to respond, causing symptoms like fever and fatigue.

• Some viruses cause mild illnesses, while others can cause severe diseases.

Sentence Starters:

• "Viruses cause disease because they..."

• "When a virus infects a cell, it..."

• "The body reacts to a virus by..."

Viruses vs. Cells: Structures and How Viruses Cause Disease

Viruses and cells are both important in biology, but they have very different structures and functions. Cells are the basic units of life; they have organelles, a cell membrane, cytoplasm, and carry out all the activities needed to live. Viruses, on the other hand, are much simpler. They are not considered living things because they cannot reproduce or carry out life functions on their own. Viruses consist of genetic material (DNA or RNA) inside a protein coat, and sometimes a lipid envelope.

Viruses spread by entering living cells and using the cell’s machinery to make more viruses. This often destroys the cell and causes disease in the organism. When viruses multiply, they can spread to other cells and even to other people, causing outbreaks of illnesses.

Below you will find sentence starters and Spanish translations for key vocabulary words to help you with this worksheet.

Vocabulary with Spanish Translation:

• Virus — virus

• Cell — célula

• Protein coat — cápsida proteica

• Genetic material — material genético

• Envelope — envoltura

• Reproduce — reproducir

• Host — huésped

• Spread — propagarse

• Structure — estructura

Sentence Starters:
