WebJul 20, 2024 · Most microbes are made of only one or a few cells. Every microbial cell is surrounded by a cell membrane. The membrane controls the movement of material in and out of the cell. This allows the cell to bring in important material, like nutrients, while expelling waste. Some microbes are also surrounded by a cell wall. WebMany types of bacteria have extra cell structures to help them to survive. For example, they may have: Flagella - tail-like structures that allow bacteria to move through liquids;
WebFlagella (singular: flagellum) are tail-like cellular structures used for locomotion by some bacteria, archaea, and eukaryotes. Because they are so thin, flagella typically cannot be seen under a light microscope without a specialized flagella staining technique. WebNational Center for Biotechnology Information

Flagella can only be observed directly by electronic microscope or by light microscope after special staining (Figure 1.7(C)). The flagellum is involved in the pathogenesis of some diseases and is antigenic (for example, antigen H).
WebSep 9, 2024 · Pili and flagella perform crucial actions on the bacterial cell surface such as motility, adhesion and the uptake and excretion of proteins and DNA. These structures can grow to many times the size of the cell, withstand and generate high forces and form and disassemble rapidly in response to environmental cues. Do bacteria have pili?
