The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. Motility Test (Theory) - Amrita Vishwa Vidyapeetham Virtual Lab Brownian Motion was discovered in 1827 by the botanist Robert Brown. Explain how trace elements move from the environment into an organism's body. Motility is closely linked with chemotaxis, the ability to orientate along certain chemical gradients. Most rods and spirilla are motile by means of . The most widespread mechanism is flagellar movement which allows travel in a liquid medium and is mediated by special threadlike organelles extending from the cell surface called flagella. 0:00 / 3:16 .

In our lab, determining the presence or absence of flagella is done by indirect methods, as we detect whether or not motility is evident under growth conditions made as favorable as possible for the organisms. One must, of course, discount Brownian motion, the movement due to bombardment of submicrosopic particles in the liquid, where the cells (alive or dead) appear to remain in one position but shake somewhat.
