The two classifications was first proposed by Aristotle two kingdoms are plantea (plant) and animilia (animal) animal can make their own food on their day while animal cannot make their own food own their body.
What is 2 and 3 kingdom classification?
In 1866 erast hackle he proposed third kingdom i.e protista
He accommodate euglena like organisms in this kingdom
Bactria is also place in kingdom protasta but this system fungi placed in kingdom plenty
Who gave the five kingdom classification system?
E
In 1937 e chat ton used the term of precarious to describe bacteria cell excoriation to describe animal cell and plant cell
ROB ART WHITTIER
In 1967 Robert Whittier proposed five kingdom classification
system
this system based on
level of cellular
organization prokaryotic unicellular eukaryotic and malts cellular eukaryotic
mode of nitration i.e photosynthesis observation and ingestion
in 1988 masculism and Schwartz on modified five kingdom classification
level of cellular organization mood of nutrition
defect of two kingdom classification system
many unicellular organisms like euglena have plant like pressure of chlorophyll and animal like absence of cell wall characteristics
so there should be a separate group for such organisms
this system also ignore different between prokaryotic cell and eukaryotic cell
five kingdom
monera
are unicellular prokaryotes
sometimes these unicellular organisms from chain,clusters or colonizes
they be heterogeneous e.g Bactria
they may be autographs e.g cyanobacteria
protista
it include unicellular ,colonial or simple multicullalur organisms
algae
unicellular ,colonial or simple multicellular organisms
thay have chlorophyll present in they have chlorophyll present in chloroplast presence of cell wall
simple multicellular mean they do not have sex organs so no embryo formed during life cycle
protozoans
they are animal like organisms lack cell wall and chlorophyll
fungi like organisms
some protista are fungi like
fungi kingdom
multicellular eukaryotic absorptive heterotrophs
cell wall is made up of chitin
most fungi are decomposed
they release digestive enzymes on body of death organisms these enzymes convert in to smaller pics
kingdom plan tea
multicellular eukaryotic autotroph
they can proposed their own food due the presence of chlorophyll
they have sex organs and from embryo during their life cycle
plants have cell wall made up of cellulose
they do not show any movement
kingdom animalia
multicellular eukaryotic consumer
they get their food from producers
they-ingest ford and digest their food within specific carves
they lack cell wall and show movement
