i-b Penicillium is an important genus of the phylum Ascomycota. Penicillin is an antibiotic that is obtained from the fungus Penicillium. It is the first antibiotic which is produced by Alexander Fleming in 1929. ii-c Bacteria are the most primitive, unicellular organisms.

A diplococcus is a round bacterium that typically occurs in the form of two joined cells. They are spherical shape bacteria. iii-a Bacteria are unicellular organism. Streptococci are Gram-positive, nonmotile, cocci that occur in pairs or chains. Streptococcus is a genus of bacteria that often occurring in chains of varying lengths.
