viruses and prokaryotes

prokaryote

Unicellular organism that lacks a nucleus

bacillus

rod shaped prokaryote type

coccus

spherical shaped prokaryote type

spirillium

spiral shaped prokaryote type

flagellum

structure used by protists for movement

photoautotroph

photosynthetic organism that utilizes energy from light to synthesize organic minerals

chemoautotroph

derives energy from oxidization of organic compounds

photoheterotroph

an organism that depends on light for most of its energy

binary fission

asexual reproduction replicates DNA and divides it in half

conjugation

a process in which paramecia and some prokaryotes exchange genetic information

endospore

a structure produced by prokaryote types in unfavorable conditions

nitrogen fixation

a process of converting nitrogen gas into nitrogen compounds that plants can absorb and use

pathogen

a disease causing agent

antibiotic

compound that blocks the growth and reproduction of bacteria

virus

particle made of proteins, nucleic acids and sometimes lipids that can replicate only by infecting cells

capsid

protein code that surrounds the virus

lytic infection

a virus enters a cell, makes copies of its cell and then bursts

lysogenic infection

infection where a virus embeds its DNA into the DNA of the host cell and replicates

retrovirus

RNA virus that contains RNA as its genetic information

prion

protein particles that cause disease

bacterialphage

a kind of virus that infects bacteria
