Smallest Cells?
viruses
Largest Cells?
Plant Cells
Are these units in the proper order for smallest to largest? (meter, micrometer, millimeter,
nanometer)
No, Nano, Micro, Milli, Meter
Among virus particles, bacteria, fungi, protistans, and plants which can be pathogens
Viral Particles, Bacteria, Fungi
What are the energy (H’s & electrons) sources used by bacteria?
Photoautotrophs are photosynthetic and use light
Photosynthetic
use light energy and get carbon by breaking down organic compounds in their environment
Chemosynthetic
get energy by removing electrons from inorganic molecules such as sulfides
heterotrophic
get carbon and energy by breaking down organic compounds assembled by other organisms
Spherical bacteria term
Coccus
Rod shaped bacteria
Bacillus
What is peptidoglycan, and where is it found?
Peptidoglycan is a network of polysaccharide molecules connected by polypeptide cross
links found in bacterial cell walls
Haploid bacterial chromosome description
circle of a double stranded Dna that reside in bacterial cytoplasm
What type of prokaryote would live typically in swamp muds and produce methane?
Methanogens
What are Archea
methanogens extreme halophiles extreme thermophiles
What is a retro virus
an RNA virus that is replicated in a host cell via the enzyme transcriptase to produce dna from
its Rna genome
Paramecium
a free living ciliate common in lakes and ponds;
plasmodium
a single celled apicomplexan, causes malaria
What bacterial structures would be found outside the cell membrane?
Bacterial flagglum , pilius, outer capsule
What are the smaller-than-the-chromosome, circles of DNA in bacteria called?
Plasmids
How are plasmids passed between cells?
passed through sex pilius
Which 5 common diseases have a viral cause?
adnenoviruses, gastroenteritis,HPV, herpes and chicken poxs
Which 5 common diseases have a bacteria cause?
lyme staphylococcus mycobacterium tuberculosis streptococcus and cibotulinum
Lytic pathway
bacteriophage replication pathway in which a virus immediately replicates in its host to
kill it
Lysogenic pathway
viral dna becomes a integrated into the host chromosomes and is passed to the hosts decendants
what items do viruses lack
viruses do not have organelles or a nucleus
Why isn’t a bacterium placed in the groups of protista?
its prokaryotic and protistas are eukaryotic
Describe the usual cell-number and nutritional mode of the protistans.
single cell and multi cellular heterotrophic and autotrophic
