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
