A single flagellum lies in the transverse groove between the cell plates.
A single flagellum lies in the longitudinal groove between the cell plates.
Two flagella, one lies longitudinally and the other transversely in a furrow between the wall plates.

only RNA.
only DNA.
RNA and DNA both
RNA or DNA i.e. one nucleic acid in a virus.
are small, microscopic which are not seen with naked eye.
cause serious diseases to human being, domesticated animals and crop plants.
produce endospores which are very resistant to adverse conditions.
possess incipient nucleus and show amitotic division.
They are archaebacteria.
They live in marshy areas.
Methane is their preferred carbon source.
They are present in guts of several ruminant animals (cow, buffaloes) and produce biogas (CH4) from the dung of these animals.

their nucleic acid must combine with host DNA before replication.
they cannot replicate.
there is no hereditary information.
RNA can transfer heredity material.
They are parasitic forms which cause diseases in animals.
They have a protein rich layer called pellicle.
They have indestructible wall layer deposited with silica.
They are commonly called dinoflagellates.
Viruses are obligate parasites.
Viruses can multiply only when they are inside the living cells.
Viruses cannot pass through bacterial filters.
Viruses are made up of protein and DNA or RNA (never both DNA and RNA).
