BIOLOGICAL CLASSIFICATION Flashcards
Earliest classification based on:
Human needs ( Food shelter clothes)
Cell wall of Monera
Polysaccharides and amino acids (non-cellulosic)
2 kingdom Classification by and on the basis of~
Linnaeus on the basis of Cw
Nuclear Membrane absent in only 1 kingdom?
Monera
Fungi Cell wall:
Chitin
3 kingdom Classification given by:
Ernst Haeckel
Order in which kingdoms were added:
Plantae and Animalia initially,
Protista Monera Fungi
Bacterias are sole members of:
Monera Kingdom
Oldest Moneras? Where are they found?
Archeabacteria.
Extreme habitats ( deep oceans, lava, deserts)
Criteria used by Whittaker for 5 KC:
Phylogeny
Reproduction
Cell structure
Body Organization
Nutrition
4 KC given by:
Copeland
Mode of Nutrition in Monera
Auto ( Photo and Chemo)
Hetero (Sapro and Para)
Mode of Nutrition in Protista:
Auto ( Photo)
Hetero
Mode of Nutrition in Fungi:
Hetero ( Sapro and Para)
Mode of Nutrition in Plantae:
Auto ( Photo)
Mode of Nutrition in Animalia:
Hetero ( sapro and holo)
Cell wall absent in:
Animalia
Drawbacks of 2 KC:
Did not differentiate b/w:
- Unicellular (chlamydomonas) and Multicellular (spirogyra)
- Prolaryotes and Eukaryotes
- Autotrophs (green plants) and Heterotrophs (fungi)
Who gave 6 KC:
- Carl Woose
- Divided kingdoms into 3 domains:
a) Archae
b) Bacteria
c) Eukaryo
Which kingdom’s boundaries are not well defined:
Protista
Flagella present in which shape of Bacteria?
Spirilla
Structure simple Behaviour Complex?
Bacteria
5 types of Protistas:
- Chrysophytes
- Dinoflagellates
- Slime Moulds
- Euglenoids
- Protozoan
Shape of Bacteria that causes cholera?
Vibrio
Nucleus and mb organelles present in:
Protista
Protistas have flagella or cilia?
Yes both
3 types of Archeabacteria?
- Halogens => extreme salty areas
- Thermo-acidophiles => hot molten lava, hot sulphur springs
- Methanogens => Gut of Ruminant animals and Marshy areas
Cw of Eubacteria?
Rigid made of Peptidoglycan
Smallest Living Organism:
Mycoplasma
Forms algael bloom in polluted waters?
Bg algae/cyanobacteria
Can pass through bacteria proof filters?
Mycoplasma
Heterocyst perform?
No² Fixation by nitrogenase enzyme
How have Heterocysts specialized?
Cells perform Co² fixation. HC specialize by:
1. Being thick Walled => O² inside ×
2. Losing Photo system 2 => H²O splitting ×
Anaerobic conditions created
Methanogens used in:
- Sewage Treatment
- Producing Biogas
Habitats of Cyanobacteria
