Biological Classification Flashcards
The arrangement of organisms into group(taxa) based upon their distinctive characteristics reflecting their similarities and dissimilarities is?
Classification
How many system of classification do we have?
Name them?
3
- Artificial system of classification
- Natural system of classification
- Phylogenetic system of classification
The system of classification based on habitat and external features is?
Artificial system of classification
The system of classification based on natural affinities among the organisms and also based on the consideration of the morphology, ultrastructure, anatomy, embryology and physiochemistry is?
Natural system of classification
In the study of Taxonomy under system of classification
1. ________ is based on the study of chromosomes number, structure behavior during cell division
2. _________ is based on the different chemical constituents of the organisms?
3. ___________ is based on number and codes ?
4. ___________ is based on morphological features?
5. ___________ is based on morphological, anatomical, cytological, embryological features and biochemistry?
6. ____________ is based on experimental, genetic and evolutionary evidences
- Cytotaxonomy
- Chemotaxonomy
- Numerical taxonomy
- Alpha Taxonomy
- Beta Taxonomy
- Gamma Taxonomy
The system of classification based on evolutionary relationship between different organisms is?
Phylogenetic system of classification
The system of classification that assumes that organisms belonging to the same taxa may have a common ancestor is?
Phylogenetic
How many kingdom did Linnaeus classify?
Name them?
What year?
- 2 Kingdoms
2a.Kingdom plantae
b. Kingdom Animalia - 1758
Who founded the kingdom Monera
And what year
Lynn Margulis and copeland in 1956
Who founded the kingdom prostista?
Ernst Haeckel
Who founded the kingdom fungi? And what year?
Robert Harding Whittaker in 1969
Who proposed the three domain of life and six kingdom classification?
And what did he propose?a
Carl Worse and this domains are, Archaea, Bacteria and Eukarya
He proposed that on the basis of differences in 16S rRNA genes, each domain arose separately from an ancestor called progenote
Name the types of archaebacteria we have
- Methanogens
- Halophiles
- Thermoacidophiles.
The type of bacteria that is strictly anaerobes, and are present in gut of several ruminants, and also found in marshy areas is?
Methanogens
The type of bacteria that is mostly anaerobes, and are found in salty environments likes marshes, salt lakes, and also convert light energy to ATP is?
Halophiles
Halophiles contains what?
Halorhodospin
Temperature and acid loving bacteria are known as?
Thermoacidophiles
The type of bacteria that can occur in hot sulphur springs and can live in extreme temperature and acidic PH is?
Thermoacidophiles
Thermoacidophiles survive in extreme temperature and acidic pH why?
Because there is presence of special branched chain lipids in their cell membrane which reduces cell fluidity
Unicellular organisms call wall are made up of
Peptidoglycan l
The cell wall of plants is made up of?
The cell wall of fungi is made up of?
Fungi store their foods in form of?
Cellulose
Chitin
Glycogen, also animals
The protective coat which surrounds a virus is known as?
And is made up of
Capsid
Capsid is made up of protein
What causes potato spindle tuber disease?
What disease do prions cause
Viroids
They cause; bovine spongiform encephalopathy(BSE) commonly called mad cow disease in cattle
And also Cr-Jacob disease (CJD) in himand

- The level of taxonomy which deals with intraspecific and evolutionary sequence and also a casual interpretation of organic diversity is ______?
- Alpha Taxonomy
- Beta Taxonomy
- Gamma Taxonomy
__________ is the methodology and principles of systematic botany and zoology and sets up arrangements of the kinds of plants and animals in hierarchies of superior and subordinate groups?
Taxonomy
