7th grade
3.1.7.A1:
Describe the similarities and differences of physical characteristics in diverse organisms.
Monday HW Biology4kids quiz on cells use Cornel Method or No Credit
Classwork
Period 1 will be working on PJAS in the computer lab Mon. and Tues.
Period 8 will be going to the computer lab Thursday and Friday.
If you finish and have a procedure in the drop box then you are to start this class work.
You will be assigned a group to work within, but until we can group, you may start your
homework.

In your notebook create the table below…title it bacteria to virus…update your table of
contents…. using information presented

Contrast
Bacteria
Reproduction
Binary Fission chromosomes
replicate cell divides into two
identical cells
No nucleus
No membrane bound
organelles
Circular DNA
Destroyed by antibiotics
Have a plasmid
Alive
Conjugation or when DNA is
exchanged between two
bacteria makes genetic
variation
Can grow on any surface
Can die
More bacteria in body than
cells
98% of bacteria are good
bigger
Can cause diseases
Destroyed by antibiotics
Need certain bacteria in your
gut always everyone
Virus
Taking over the host cell and
either takes over ribosomes
and metabolic process
forcing it to make copies of
the viral RNA/DNA or lays
dormant
No Nucleus
Capsule like Protein with a
surrounding envelope
Double stranded or single
stranded DNA or rNA
Antibiotics do not work to
destroy or have any affect
Vaccines stops the spread
and antiviral slows
reproduction
No plasmid
Not Living
Genome is inserted into the
host so the same in the
beginning when dormant
Needs a host
Only dies by killing host cells
smaller
Can cause diseases
Vaccines stops the spread
and antiviral slows
reproduction
Not really helpful recent
research shows may be
useful in genetic engineering
or in fighting certain brain
Flagellum
Cell wall
Strep throat
tumors but not accepted yet
Tail Fibers
Protein coat
flu
