Smaller Things - Bacteria
A simple bacterium. The DNA is in the Nucleoid or the cell and is nor contained within a separate membrane. In this model representation, the Ribosomes are depicted as a granular texture along the cell membrane. Projecting from the walls of some bacteria are pili (singular: pilus) - shorter than flagella (singular: flagellum), which are concerned with cell-to-cell or cell-to-surface attachment. They are 'sticky'. Like all cells, the living material is surrounded by a partially permeable membrane, also the site of respiratory enzymes. Motile bacteria can move in response to certain stimuli, for example - aerobic bacteria will swim towards oxygen, whereas photosynthetic bacteria will move towards a light source.
