Cells and Cell Theory
Which things are made of cells?
All living things are made of cells.
Are viruses alive? Explain.
No, viruses are not alive. They are DNA within a capsid (proteins)
How does a vaccine work?
Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick
Are bacteria alive? Why or why not?
Yes, they are unicellular organisms that reproduce and follow the characteristics of life.
What's larger: a virus or bacteria?
Bacteria are larger than viruses.
What are the major differences between a plant cell and an animal cell?
A plant cell has a cell wall and chloroplasts.
How are viruses treated?
Antiviral medicine can help your body fight off certain viruses or you can get a vaccine to prevent being infected with a viral disease.
Provide two different reasons why someone might refuse a vaccine.
Animal rights, veganism, religious objections, anecdotal evidence that vaccines are harmful...
How are bacterial infections treated?
They are treated with antibiotics.
Explain why a tree is alive, using the characteristics of living things.
Answers vary.
List 5 organelles and their function.
Nucleus, Endoplasmic reticulum, chloroplasts, vacuoles, cell membrane, cell wall, ribosomes, golgi apparatus, mitochondria, etc.
List at least three types of viruses.
Covid-19, the flu, measles, mumps, rubella, smallpox, tobacco mosaic virus, etc.
Explain how "herd immunity" works.
Herd immunity is when a large part of the population of an area is immune to a specific disease. If enough people are resistant to the cause of a disease, such as a virus or bacteria, it has nowhere to go. While not every single individual may be immune, the group as a whole has protection
List at least two types of bacterial infections
Strep throat, skin diseases, E. coli, Salmonella, Meningitis
List the 7 Characteristics of Living Things
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, Nutrition
What is the difference between a prokaryotic cell and a eukaryotic cell?
Prokaryotic cell does not have a membrane-bound nucleus. A eukaryotic cell does.
What are the three major types of viruses?
Animal virus, plant virus, and bacteriophages
How does an mRNA vaccine work?
It uses messenger RNA to code instructions for a protein located on the outer edge of the virus. When injected with the vaccine, we begin creating antibodies to fight the virus.
What kind of cells are bacteria made up of?
Prokaryotic cells
How tall is Ms.Hasbrouck?
