Biological Classification Flashcards
…………… was the earliest to attempt a scientific basis of classification
Aristole
Aristole classifed plants into ………….. , …………….. and ……………
Trees , shrubs and herbs
He divided animals into ……………. no. Of groups , one with………….. and one thoses did not
Two groups ,
Red blood
Monera cell wall is made up of
Polysaccharide and amino acids
All protist don’t contain cell wall T/F
F
+nt in some
Loose tissue body organisation is present in
Fungi
Monerans cannot be saprophytic T /F
F
Holozoic mode of nutrition is present in which kingdon
Animalia
The animalia kingdom contains saprophytic animals T/F
F
Whittaker five kingdom classification in which year
1969
Criteria’s use by whittaker for classification was
Cell structure body organisation mode of nutrition reproduction and phylogenetic relationship
Earlier chlamydomonas and spirogyra where place together under
Algae
Kingdom ………….. has brought together …………. and ………….( having cell walll ) with ………… and …………. ( lacking cell wall )
Protista , chlamydomonas and chlorella , paramoecium and amoeba
Phylogenetic means
Base on evolutionary relationships
…………….. are the sole members of Kingdom Monera
Bacteria
Bacteria 4 classification on the basis on shape
Cocus bacillus vibrium spirullion
Bacterial structure is very complex yet they are very simple in behaviour true or false
False
The ………….. shows the most extensive metabolic
Bacteria
Vast majority of bacteria are autotrophs true or false
False
…….. bacteria live in most of the harsh habitats
Archaebacteria
Name the three divisions of archaebacteria and their habitat
Extreme salty areas halophils , hot springs (thermoacidophils ) amd marshy areas ( methanogens)
Archaebacteria differs from others by having
Different cell structure , branched chain lipids
The reason for survival of archaebacteria in extreme condition is
Different cell wall structure and absence of peptidoglycan is responsible for survival in extreme conditions
…….. are present ingut of ruminants
Methanogens
Methnogens are chdmoautotrophs or chemoheterotrophs
Chemoautotrophs
Eubacter have rigid cell wall true or false
True
Eubacteria if motile contains cilia true or false

Heterotrophs
Nostoc is a filamentous/unicellular cyanobacteria
Filamentous
…………are helpful in making curd from milk, production of antibiotics
