Cilia are relatively thinner when compared to Flagella actually extend from the interior of the cell body. In medical situations, they are major determinants of bacterial virulence because they allow pathogens to attach to (colonize) tissues and, sometimes, to resist attack by phagocytic white blood cells. Extracellular non-flagellar appendages, called pili or fimbriae, are widespread in gram-negative bacteria. They function to attach the cells to surfaces. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. Non-motile or primary cilia are found in the olfactory sensors located in the upper part of the nasal cavity.
