Flagella is the tail-like piece connected to the Cell Body of certain prokaryotic and eukaryotic cells and it functions in locomotion. The Cilia is an organelle found in eukaryotic cells that also project from the cell body. In Eukaryotic Cells the Cilia and Flagella make up a group of organelles called the undulipodia and the Cilia and Flagella are structurally similar.
flagella stain Purpose: To determine the presence/absence and location of flagella on various microorganisms Principle: Because bacterial flagella are very thin and fragile a special stain (flagella stain) is prepared that contains a mordant. This mordant allows piling of the stain on the flagella, increasing the thickness until they become visible. Various arrangements of flagella are seen on different cells.
Flagella are the locomotory organelles of many species of bacteria. They are located at the posterior end of the bacterium and carry out either a spiral or lashing movement. This process is able to propel the bacterium to a region where nutrition is present. Flagellar movement is an active process, which means it requires energy.
