gram staining
What stain stains the gram negative bacteria?
safranin
cells in a cluster arrangment
staphylo-
key component bacteria cell wall
peptidogylcan
single celled eukarya
protozoa
2 basic forms fungi
yeasts and molds
What stain stains the gram positive bacteria?
crystal violet and gram iodine
coccus
function to promote bacterial survival in nutrient depletion
sporulation
two parts of protozoan cytoplasm
ectoplasm and endoplasm
long, threadlike cells in filamentous cells
hyphae
distinguishing features of gram negative bacteria
lipopolysaccharides, outer membrane (double membrane), thin layer peptidoglycan
rod shaped cells
bacillus
surface coating of repeating polysaccharide/glycoprotein units
glycocalyx
3 manners of protozoa locomotion
ameoboid movement, ciliary movement, flagellar movement
symbiotic association roots and fungi
mycorrhizae
distinguishing features of gram positive bacteria
thick layer peptidoglycan, just a cytoplasmic membrane
cells in a "cone" arrangement
palisade
bacterial extensions for adhesion
axial filaments
main limiting factor protozoan habitat
moisture
mycoses
gram positive vs. acid fast
acid fast: subset gram positive bacteria with a high lipid content (waxy)
cells in a linear arrangement
strepto-
flagellar arrangement of whole cell covered with flagella
peritrichous
motile feeding stage of protozoa
trophoziote
main structures of molds
mycelium (woven mass hyphae that makes up body/colony of molds), septa (solid partitions or parital walls with small pores to allow flow organelles between compartments)
