What questions would you like to ask your teacher to know about different shapes of Bacteria?

I would like to ask following questions about different shapes of Bacteria to my teacher:

● Do bacteria exist in different shapes?

● What advantages does the shape of bacteria confer to them?

● Why don’t all bacteria have one fixed shape?

● Does altering the shape of bacteria can help us to kill the bacteria or causing any harm to it?

● Does shape of bacteria is in some way related to its motility?

● Does in a different stage of their lives bacteria exhibit different shapes or they exhibit the same shape during their complete life cycle?

● Does their shape also contribute in their microscopic nature?
