Question

what will happen to a bacterial cell with a damaged cell wall, if placed into a hypotonic solution?

what will happen to a bacterial cell ( with an intact cell wall) in a hypertonic solution?

what potentially medically- important genes might be on a plasmid?

What is an interesting feature of plasmids that enable the spread of antibiotic resistance?

Answer 1

1. Bacterial cell wall is Rigid and maintains the shape and doesn't allow to killing of bacterial cell when placed in hypertonic solution.

2. Bacterial cell without cell wall undergoes dehydration upto killing of bacterial cell when placed in hypertonic solution.

3. Potentially medically important gene are mainly antibiotics resistant genes which allows the bacteria to grow even in presence of antibiotics in the media and also provide the selectable markers for selection purpose.
