Question

What are the ways bacteria can move through their world? Describe some mechanisms of motility. Come up with at least 2 possible alternative explanations for the amazing redistribution of the etpum on the lycra-sealed slide. Both of your explanations should consider how the microbes sensed the presence of polyurethane. One of your answers should not involve flagella?

Answer 1

Bacteria use a number of ways to move from one place to another. For example, other than flagella they can use gliding movement or twitching movement as mode of transportation.

Further explanation

Bacteria

They are single-celled living creatures and they are not included in plants or animals. They usually measure several micrometers in length and exist together in systems of millions. A gram of soil generally contains around 40 million bacterial cells.

Motility in bacteria

They use different patterns of movement.  

Gliding movement

This kind of motility is found in an enormous number of phylogenetically different bacterial organisms. It offers an approach to life forms to go in conditions with low water content, for instance, possibly found in biofilms, microbial tangles, and soil. Floating is described as the improvement of a cell on a surface toward the long turn of the cell. Mycoplasma uses gliding movement.

Twitching movement

It is a kind of crawling bacterial motility used to move over surfaces. Twitching is interceded by the development of hair-like filaments got type pili which connect from the body cells, bind to incorporating solid substrates and pull back, pulling the cell progresses in a manner like the action of a catching snare. It has been found in various bacterial species, nonetheless, is most all-around packed in Pseudomonas aeruginosa.

Answer 2

The bacteria can move by the means of swimming, pushing, twitching and gliding. They can also move randomly. They do not need any specific structures for their movements. Taxis, pilli, flagella and actin helps in their movement. The bacterial cell have the ability to move via taxis and can also use their pilli in order to move together. That is the reason the ETPUM on the Lycra-sealed slide is redistributed. The bacterial cells using taxis can gain energy from the polyurethane.
