EXP. #1:
, Aseptic technique Procedures that prevent microbes from getting
where they do not belong (contamination). This
includes microbes from the environment contami-
nating your lab area as well as any microbes under
study contaminating you or your work area.
Bibulous paper Specially prepared blotting paper that contains a
minimum of loose paper fibers.
Eukaryotic Cells with a true nucleus and paired chromosomes.
Parfocal Feature of most microscopes that sets the focal point
of all objective lenses at the same location in space
Prokaryotic Cells with no true nucleus (membrane covered, paired
chromosomes), with only one circular chromosome.
Resolution The ability to see a small object clearly under the
microscope (technically, minimal distance at which
two adjacent small objects can be distinguished as
separate).
Rheostat Device that controls the amount of electrical current
and thus the amount of light emanating from a bulb.
EXP. #2:
Agar Solidifying agent used for growth media derived
from seaweed.
Agar deep Growth medium in a test tube allowed to solidify as
the tube sits in a test-tube rack.
Agar plate Solidified growth medium in a lid-covered, flat dish.
Agar slant Solidified growth medium in a test tube, allowed to
solidify at an angle, thus presenting a large surface
area to allow for growth.
