Cell structure - prokaryotes Flashcards
prokaryotic cells are … than eukaryotic cells
smaller
how does the cytoplasm of a prokaryotic cell differ from a eukaryotic cell
-no membrane bound organelles
how is DNA stored in a prokaryote
no nucleus
DNA free floats in cytoplasm
circular DNA, not associated with proteins
what is the cell wall made of in a prokaryote
murein
what is murein
a glycoprotein
that makes up prokaryotic cell wall
what is a glycoprotein
protein with carbohydrate attached
what can a prokaryote contain one or more of
Plasmid
flagella
capsule surrounding cell
plasmids are
small loops of DNA
a flagella is
long hair structure
that rotates
allowing movement
a capsule is
secreted slime
protects bacteria
viruses are
acellular
non-living
basic structure of virus
genetic material - a core
capsid - protein coat
attachment proteins - let virus cling onto host cell
what is a host cell
a cell a virus reproduces inside of
why are viruses acellular
not made of/ unable to divide into cells
why are viruses non-living
unable to exist/reproduce without host cell
how do bacteria divide
binary fission
how do viruses reproduce
bind onto host cell
inject genetic material into cell
use host cell’s ribosomes to reproduce
burst out host cell
