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