The rod shape(bacilus) and the sphiral(sphirily) have flagella. They both have same structure of flagela but there is a difference between gram positive and gram negative,s flagellum structure.
Some methanogenic bacteria (which are anaerobic) do have flagella. You can read more in the related link
The two organelles that help bacteria move are flagella and pili. Flagella are long, whip-like structures that help bacteria move in a fluid environment, while pili are shorter, hair-like structures that help bacteria attach to surfaces and move along them.
Bacteria can be classified based on the number and arrangement of flagella. Monotrichous bacteria have a single flagellum, amphitrichous bacteria have a flagellum at each end, lophotrichous bacteria have multiple flagella at one or both ends, and peritrichous bacteria have flagella distributed all over the cell surface.
Flagella help bacteria to move and navigate through their environment. They allow bacteria to swim towards nutrients or away from harmful substances. Flagella also help bacteria to colonize surfaces and form biofilms.
Flagella on any cell (including bacteria) move it towards some goal.
A penicillum does not have flagella, it is a drug, or antibiotic
Flagella
Some bacteria have a whip-like tail called aflagellum. This structure is essential for locomotion, or motility.
The role of a flagella in a bacterial cell is motility. Through the back and forth movements of the flagella bacteria can propel themselves through their environment. The flagella also help bacteria undergo chemotaxis, the ability to move away from some stimuli and move towards others.
Some bacteria have flagella, some only have one flagellum, and some just float around like a leaf in a river
No, flagella are used for movement, not for conjugation in bacteria. Conjugation involves the transfer of genetic material between bacteria through a pilus, a specialized appendage.
