Adv. Bio Test:2 Flashcards
(32 cards)
RNA virus, such as HIV, with reverse transcriptase in its core
Retrovirus
lives in hot acidic environments, including hot springs and deep sea vents
Thermoacidophiles
live in salty environments
Halophiles
obligate anaerobes-won’t live in the presence of oxygen, obtain energy through fermentation
Methanogens
submicroscopic hair like structures
Pili
make proteins
Ribosomes
genetic structure
Chromosomes
tough layer protecting the cell
Capsule
protect cell
Cell Wall
longer tail-like structure for movement
Flagella
smaller piece of DNA, circular arrangement
Plasmid
dark purple, large amount of peptidoglycan
Gram-positive
light pink, small amount of peptidoglycan
Gram-negative
division of cells into 2 genetically identical cells
Binary Fission
2 prokaryotes attach and exchange genetic information new gene combinations
Conjugation
2 prokaryotes attach and exchange genetic information new gene combinations
Conjugation
similar to plants, need light, were called blue-green algae- renamed to cyanobacteria, ecological important
Phototrophs
cannot make own food, many are saprobes- live off of decaying matter
Heterotrophs
do not require light, relate inorganic compounds
Chemoautotrophs
do not require light, relate inorganic compounds
Chemoautotrophs
structure produced when conditions are harsh
Endospores
the way bacteria provides energy
Chemosynthesis
bacteria that lives in or on you
Normal Flora
nonliving strand of genetic material with a protein coat; smallest disease causing structure
Virus
