| |
Archaebacteria |
Kingdom of unicellular prokaryotes whose cell walls do not contain peptidoglycan |
| |
Prokaryote identification |
Identified by shape, cell walls, movement, ways to obtain energy |
| |
Bacilli |
rod shaped |
| |
cocci |

| |
cell wall (gram stain) |
gram positive- violet gram negitive-pink |
| |
flagella |
long whip like structure |
| |
lash |
snake, spiral |
| |
slime |
they secrete |
| |
photoautotroph |
photosynthisize similar to plants |
| |
chemoautotroph |
energy(sulfer) form inorganic molecules |
| |
heterotrophs |
use energy from ofganic molecules |
| |
photoheterotroph |
need food and sunlight |
| |
Binary Fission |
a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size- prokayotes |
| |
process of binary fission |
1) DNA replicates 2) DNA attaches to membrane 3) cell elongates by water uptake 4) cell splits |
| |
conjunction |
form of sexual reproduction where cells share/exchage genetic info through a hollow bridge |
| |
decomposer |
eats and breaks down dead matter |
| |
Nitrogen fixers |
convert nitrogen into nutrients |
| |
legumes |
symbiotic relationship with nitrogen- fixing bacteria |
| |
biotechnology |
food, medicine,industry |
| |
disease |
any change,other than injury, that disrupts the normal functions of the body |
| |
pathogens |
disease-causing agent such as bacteria or fungus two or more ways- virus, amoeba |
| |
Damage tissue |
tuberculosis, tooth decay, pneumonia |
| |
other disieses (bacteria) |
strep throat, salmonella, tetnus, botulism |
| |
antibiotic |
blocks growth and reproduction of bacteria |
| |
sterilization |
destroys bacteria using high heat or chemical: no bacteria left 212 F |
| |
disinfection |
chemicals that kill bacteria |
| |
dehydration |
remove water |
| |
satling |
chemical treatment: hinders growing condition |
| |
pasturization |
flash heat to lower population: kills pathogens |
| |
other ways of controlling bacteria |
preseves and cooling |
| |
Viruses |
particle made up of nucleic acid (DNA,RNA), protein, and in some cases lipids that can replicate only by infection living cells |
| |
Viruses (living) |
Viruses are not alive |
| |
Bacteriophage |
virus that infects a bacteria |
| |
Lytic infection |
virus enters cell, make copies of itself, causes cell to burst |
| |
Lysogenic Infection |
virus embeds its DNA into the DNA of the host and is replicated along with the host DNA. |
| |
Human protection |
vaccines- injection with weakened virus that triggers human immune system to make antibodies |
| |
examples of viruses |
polio, measels, AIDs, Mumps, Influenza, yellow fever, rabies and common cold |
