Cell Flashcards
Bacteriophage
A virus that infects bacteria
Conjugation
Bacteria pass DNA from one cell to another through Pili
Capsule
Outer protein coat of a virus
Eukaryote
A cell that contains a nucleus and membrane bound organelles
Flagellum
A long, whiplike structure that helps a cell to move.
Host
An organism on which a parasite lives
Heterotroph
An organism that consumes food for energy
Multicellular
Consisting of many cells
Nucleoid
Unorganized DNA in a prokaryotic cell
Organelle
A tiny cell structure that carries out a specific function within the cell
Prokaryote
A unicellular organism that lacks a nucleus and membrane bound organelles
Pathogen
A microbe that causes disease
Pili
Hollow tubes used to exchange DNA between bacteria by conjugation
Plasmid
Small circular piece of DNA located in the cytoplasm of many bacteria
Unicellular
Made of a single cell
Virus
Nonliving pathogen that uses host to reproduce DNA. A tiny nonliving particle that invades and then reproduces inside a living cell.
Autotroph
An organism that makes its own food
Asexual
Process by which a single parent reproduces itself
Archaea habitat
Volcano, geyser, tundra, salty water, acid
Prokaryotic
Eubacteria, archaea
Name the three domains
Bacteria, archaea, eukaryotic
Bacteria shapes
rod, spiral, sphere
Bacteria
Helpful and harmful unicellular bacteria that live on and around us, prokaryote
Archaea
unicellular organism that lives in extreme conditions, prokaryote
binary fusion
reproduction of bacteria into two cells
Are Viruses living? Why?
No, because viruses do not eat grow, produce waste, or reproduce on their own.
