Students created note cards comparing characteristics of eukaryotic and prokaryotic cells.
Which set of note cards most accurately compares these cells?
Viruses can be transmitted through air, water, food, insect bites, and direct skin contact. Once a virus gains entry to the body, it invades a in order to .
The table below indicates which structures are present in two cells. The X indicates structures that are present in each cell.
Identify the cells below based on their structures.


Based on the diagram, which organism evolved first?
The organelle that produces energy for the cell () was once a cell that was engulfed by a eukaryotic cell. This theory is called the .
Due to a recent infection, the cells in your body need to synthesize (make) more enzymes, which are made of proteins, to break down the bacteria that your immune system has been killing off.
Which cell organelle will make these new enzymes?
Steven finished with his Tiger Tutorials and heads to the cafeteria for his lunch. Once he eats, his body will digest his quick carbohydrates!
Which organelle will help Steven produce energy?
The wax palm tree, native to Colombia and Peru, can grow up to 200 feet tall.
The cell wall which is high in cellulose provides the structure that the trees need to grow tall. What biomolecule makes up the cell wall?
Water is the most abundant molecule inside of a cell, however too much water entering a cell can cause the cell to burst (pop).
Which cell organelle is responsible for controlling how molecules, such as water, enter and leave the cell?
Eukaryotic cells are on average 10x larger than prokaryotic cells. Due to their larger size, eukaryotic cells are more complex and have many processes occurring within the cell.
Which cell organelle produces ATP energy to power these processes within the eukaryotic cell?
The table below displays three cell samples (X, Y, and Z). Us the information in the table below to determine which cell is represented for each sample.
Cell X is a while Cell Y is a . Cell Z is a because it lacks a mitochondria and chloroplast.
Observe the diagram below and complete the sentence.
The cell above is an example of a . This is because the cell .
Miguel would tell you that the following statement is TRUE about VIRUSES?
The difference between viruses and bacteria cells is that a virus while a bacteria .
Pathogens such as bacteria and viruses have extensions as shown in the diagrams below.
In bacterial cells, these extensions are used for motion. What are the extensions from a pathogenic virus used for?
Below is a picture of SARS-CoV-2, the virus that causes COVID-19.

Match each structure to its name.

Below is a picture of SARS-CoV-2, the virus that causes COVID-19.

Match each structure with its function (job).
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Protects the genetic material | arrow_right_alt | Structure A |
Attachment and entry into host cell | arrow_right_alt | Structure B |
Information for making viral proteins | arrow_right_alt | Structure C |
A typical virus consists of glycoproteins on the outside (keys) that match receptor proteins (locks) on host cells.
The role of these glycoproteins is to…
In order to spread, Tobacco Mosaic Virus (TMV) must infect healthy plant cells. Which statement below is true?
What does a virus need from the host cell in order to reproduce?
Select TWO correct answers.
Viruses are which means they are not alive. They require a because they reproduce on their own.
Once a virus attaches onto the host cell, it injects its into the host cell. The virus then tricks the host cell into making particles.
Observe the diagram below and complete the sentence.
The cell above is an example of a . This is because the cell .
Which statement is true of both viruses and cells?
Hector would tell you that prokayotic and eukaryotic cells are similar to Viruses, because...
A student is making a Venn diagram comparing eukaryotic cells, prokaryotic cells, and viruses
What will be in the middle of the venn diagram?
In a virus, the job of the capsid is to protect the genetic information for the virus.

A student was taking notes during class on comparing cellular structures, however they forgot to put the cell labels on their Venn diagram! Can you help them figure out their missing cell labels?
From the information provided in the Venn diagram, Cell A should be labeled as a cell and Cell B should be labeled as a cell.
Use the diagram below to complete the sentences.
RESPOND TO ALL THREE PARTS.
Structure A is a because it has and .
Structure B is a because is has and .
Structure C is a because it has a and .
Viruses have a capsid ("protein shell") which protects the . This is similar to the of a eukaryotic cell.
Which statement is best supported by the diagram?
