Primary differences between cilia and flagella are
Cilia and flagella are cell external structures that primarily aid in cell locomotion. Cilia are short, hair-like structures that cover the surface of some cells in large numbers. Flagella are long, thread-like structures that can only be found at one end of a cell.

R.H. Whittaker proposed the five-kingdom classification in 1969. This classification was based upon certain characters like mode of nutrition, thallus organization, cell structure, phylogenetic relationships and reproduction.

See lessGram staining was introduced by
Danish bacteriologist Hans Christian Gram introduced the Gram stain in 1882 to identify the organisms that cause pneumonia. The Gram stain is a common technique used in microbiology to differentiate between Gram-positive and Gram-negative bacteria.

See lessThe unifying feature of the archaea that distinguishes them from the bacteria is
The unifying feature of archaea (single-celled prokaryotes without a nucleus) that distinguishes them from bacteria is the lack of a layer of peptidoglycan in the cell wall. Peptidoglycan is a large molecule, or polymer, composed of amino acids and sugars.

See lessThe oldest eukaryotic organisms are considered to be
The oldest eukaryotic fossil is the multicellular alga, Grypania. Coiled Grypania is found as thin films of carbon in rocks as old as 2,100 Ma in Michigan and young specimens have been recovered from 1,100 Ma rocks in China.
