Cardboard comes from processed trees and plants, which are turned into wood chips that are then reduced to cellulose fibers, a main structural component of plant cell walls.
What biomolecule is cellulose, the structural component that 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 .
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?

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?
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.
What structure in a eukaryotic cell has the same function?
Decide whether each item below belongs to

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.
H1N1 flu is a highly contagious viral infection caused by the influenza A (H1N1) virus. It is transmitted rapidly though airborne droplets with infected particles. When exposed to the flu virus, people develop symptoms within days of exposure. The symptoms of H1N1 flu are listed below.
H1N1 Flu Symptoms
Acute respiratory illness
Fever
Cough
Sore throat
Body aches
Headaches
Chills and fatigue
Diarrhea and vomiting
What type of replication cycle does the H1N1 virus follow?
Is it Lytic or Lysogenic?
(See hint!)
Lytic | Lysogenic | |
|---|---|---|
Symptoms occur within days of exposure to the virus. | ||
You get sick later, months to even years after exposure to the virus. | ||
Long incubation period | ||

The diagram below represents the two replication cycles of viruses. Use the diagram to complete the sentences. NOTE: a bacteriophage is a virus that infects bacteria.
Cycle A represents the cycle because .
Cycle B represents the cycle because .
Varicella-zoster virus (VZV) is a unique virus that causes multiple illnesses in humans. After the first exposure to VZV, individuals develop itchy rashes and bumps within 14-16 days. This infection is commonly referred to as chicken pox.
The itchy rashes and bumps fade for most humans after 7-10 days. Which viral replication cycle does the varicella-zoster virus complete for this infection?
Varicella-zoster virus (VZV) is a unique virus that causes multiple illnesses in humans including chicken pox. Symptoms of chicken pox fade for most humans after 7-10 days, however the virus stays in their body for many more years without showing symptoms.
Individuals who have had chicken pox can develop shingles later in life which produce skin sensitivity, itchy patches, and red spots which may blister.
For most individuals who have had chicken pox, the symptoms of shingles do not develop for an average of 20-35 years later in their life.
Which viral replication cycle does the varicella-zoster virus complete for this infection?
Human papilloma virus (HPV) is a virus most commonly spread through physical contact. It causes skin or mucous membrane growths (warts), and has also been found to cause cancer in humans. Most individuals do not show any symptoms, but will continue spreading the virus for their entire life. While there is no cure, the most common way to prevent contracting HPV is by getting three doses of the vaccine.
Once infected with HPV, an individual has the disease for life.
Which replication cycle does the virus follow?
Which of the following best explains why plants can be affected by TMV while humans are unaffected?
Which of the following best explains why humans can contract HPV, but your pet dog cannot?
HPV is the most commonly spread STI (sexually transmitted infection), with about 1 million new cases reported each year.
Which of the following best explains why someone HPV cannot pass on the virus if they sneeze or cough?
