study of microscopic
organisms
microbiology
exist are unicellular,
multicellular, or cell clusters
microorganisms
types of microorganism
- BACTERIA
- ARCHAEA
- FUNGI
- PROTOZOA
- ALGAE
- VIRUSES
classification of organisms
- PROKARYOTES
- EUKARYOTES
range from 0.1 to
5.0 micrometers in diameters(smaller)
prokaryotic cells
ranging from 10 to
100 micrometers in diameters
eukaryotic cells
prokaryotes cellsize
0.1-5 micrometers
eukaryotes cellsize
10-100 micrometers
outer covering
that separates the cell’s interior from its
surrounding environment
plasma membrane
- jelly-like cytosol inside the
cell
cytoplasm
genetic material of the cell
DNA
synthesize proteins
ribosomes
simple, single- celled
organisms that lacks a nucleus and
membrane-bound organelles
prokaryotes
- found in a central region of theprokaryotic
cell
nucleoid
what chromosome does prokaryotes have
single circular chromosome
what chromosome does eukaryotes have
multiple linear chromosome
rigid cell wall
- a polymer composed of linked
carbohydrates and small proteins
peptidoglycan
provides an extra layer of
protection
cell wall
outermost layer of
carbhydratess and helps cells to attach to surface in its environment
capsule
whip-like structures that act as
a rotary motors
flagella
hair- like structures that are
used for attachment to host cells
fimbriae
rod-like structures
pili
membrane-bound nucleus, a
central cavity that houses the cell’s genetic
material.
eukaryotes
little organs
organelles
