MICROBIO pro-euk and bacterial structure Flashcards
prokaryotes came from the word
“pro - before” and “karyon - nucleus, nut or kernel”
organisms that do not contain true nucleus and membrane-bound organelles
prokaryotes
the functions of prokaryotes takes place in
cytoplasm or cytoplasmic membrane
components of prokaryotes
cell wall
plasma membrane
cytoplasm
dna
ribosomes
capsule
flagella
fimbriae
rigid structure that contains as peptidoglycan
cell wall
cell wall is also referred to as
murein layer
provides an extra layer of protection, helps the cell maintain its shape, and prevents dehydration
murein layer
outer covering that seprates the cells interior from its surrounding environment
plasma membrane
consists of a jelly-like cytosol indisde the cell, plus the cellular structures suspended in it
cytoplasm
the genetic material of the cell
DNA
molecular machines that synthesize protein
Ribosomes
sticky and helps the cell attach to surfaces in its environment
Capsule
whip-like structures that acts as rotary motors to help bacteria move
Flagella
numerous, hair-like structures that are used for attachment to host cells and other surfaces
Fimbriae
organisms whose cells have a nucleus enclosed w/n membranes, unlike prokaryotes, which have no membrane-bound organelles.
eukaryotes
parts of euk.cell
plasma membrane
cytoplasm
nucleus
chromosomes
nucleolus
ribosomes
mitochondria
peroxisomes
lysosomes
