Module 4 Flashcards
Plant cell walls are made of
cellulose
Blocking ribosomes blocks
protein synthesis
A researcher found new cells growing in his tissue culture. How could he rapidly determine if the cells were bacteria and not human cells?
look for plasmid
How would a researcher differentiate between two different cells in the same organism that look similar to each other?
Examine the proteome of the cells
In Tay-Sachs disease, lysosomes accumulate lipids and burst. How will this affect the cell?
Digestive enzymes will break down the cell
Mitochondria and chloroplast have their own DNA, replicate separately from the nucleus and they can synthesize ATP. Can they survive outside of the cell?
no
Dental plaque is formed when bacteria adhere to the surface of your teeth. Which bacterial structure allows for the adherence?
pilli
Which of these cells would have the largest surface area to volume ratio?
A long skinny cell with many extensions
You are interested in counting the number of ribosomes on the rough endoplasmic reticulum of a cell. To do this you should use
a transmission electron microscope
A new disease has been discovered where the individual’s proteins are often folded incorrectly. This means it is likely that they have a defect in which cellular component?
Rough endoplasmic reticulum
The word prokaryote means
before nucleus
Based on evidence from the fossil record, which type of cells came first?
prokaryotic
I am looking at a cell under the microscope and it contains ribosomes, a nucloid, cytosol and a plasma membrane. This cell is most likely
a bacterial cell
When examining lettuce under the microscope, which of these would be used to stain the cells?
IKI
The bacteria in the genus Streptococcus get their name based on their overall shape. From this you can determine that all members of the genus Streptoccus
are spherical
