Cocci type bacteria include maximum resistant bacteria, smallest bacteria I.e dialister pneumosintes.
True. Dialister pneumosintes is smallest monococcus in shape.

No
K.Monera was introduced in _____kingdom classification
4-K classification by Copeland.
K.Protista was introduced in ___kingdom classification.
3-K classification by Ernest Haeckal (1866)
Long filamentous bacteria
Beggiatoa mirabilis.
Name the largest bacteria
Thiomargarita namibiensis.
Name the smallest bacteria
Dialister pneumosintes
Term monera was given by
Allen and Dougherty.
What is 3-domains of life and who gave it?
On the basis of 16s rRNA genes, Carl Woese suggested 3-domains:-
Domain archea- K.archeabacteria
Domain bacteria- K.eubacteria
Domain eukarya- K.protista, fungi, animalia, plantae.
What was the criteria for 5-K classification by R.H.Whittakar?
1) cell structure = pro/eukaryotic
2) Thallus organisation = body differentiated into root, stem and leaves OR not.
3) Mode of nutrition = auto/hetero
4) reproduction
5) phylogenetic (revolutionary) relationship.
