, Classification of organisms
Biologists use a binomial system to classify
Systematics
:
1 .
·
researches diversity of organisms + relationships
taxonomy
:
.
2
·
subdivision of systematics involved (nomenclature
organisms are classed in this way
:
genus +
species
Eg : hano sapien
Classes of Organisms :
King Philip Came Over For Good Soup
Kingdoms :
Porganelles are
membrane bound
1 .
Plantae (multicellular eukaryotic) ,
a . animalia (multicellular eukaryotic ,
3 . Sungi (multicellular ,
eukaryotic
9 . Protista (unilmulticellular ,
eukaryotic)
.
5 Monera (unicellular ,
prokaryotic
↳ no membranes
Monera :
·
includes all bacteria
prokaryotic no true nucleus no membrane-bound organelles
·
:
,
autotrophic (chemicals + sun - food) or parasitic (feed on host)
reproduce via mitosis
Eg cocci bacilli spirilli
·
:
, ,
Protista :
·
consists of protozoans
+
algae
·
eukaryotic ; con be micellular/multicellular
live in aquatic environments
can be autolheterotrophic
·
·
reproduce via mitosis
Eg algue water slime fungi
·
: +
,
Fungi :
non-photosynthesising organisms ; feed by that digest food" absorb nutrients
·
secreting enzymes
eukaryotic ; multicellular
·
saphrophytes (decomposers) or
parasites
hyphae body ; sparagia =
spares
·
=
reproduce via spares
·
Eg :
yeast ,
mold ,
mushroom
,Plantae
autotrophic organisms that form base of food chains
·
·
eukaryotic ; multicellular
contain chlorophyll + cellulose
·
reproduce via spores ; gametes or vegetative propagation
6 categories
:
mosses , ferns, gumnosperms anglosperms etc
, ,
Animalia
heterotrophic animals that directly indirectly depend on autotrophs for energy
·
·
vertebrae + invertebrae
reproduce sexually
·
, Viruses
·
micro-organisms can be pathogeniclion-pathogenic
pathogens spread by
respiratory tract
-
GI tract
-
urogenital openings
broken skin
-
Characteristics of Viruses
very small
not living
·
obligate intracellular parasites
-relies on host to reproduce
2 phases :
virion : dormant
-
active
-
virus :
causes diseases like influenza HIV , ebola
,
Structure
no nucleus >
-
not a cell
has DNA or RNA
·
nucleic acid surrounded by protein coat (capsid)
only Reproduce inside a host
Shapes
·
:
1) Polyhedral (cubical)
2) helical (spiral)
3) complex (tadpole
Types of Viruses
virus which parasitises
bacteria
by reproducing
Inside It
