Question

A stream of water holds thriving bacteria. If drought conditions caused the stream to dry up, how would the bacteria mostly likely respond to survive?

1.They would learn how to photosynthesize.
2.They would produce more peptidoglycan.
3.They would secrete more polysaccharides.
4.They would produce endospores.

Answer 1

he answer is endospores

Answer 2

Ans.

The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions. During environmental stress, such as starvation, desiccation (extreme dry), radiation, and chemical treatment, many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.

Therefore, if drought conditions lead the stream to dry up, the bacteria that live there, would produce endospores to survive.

Thus, the correct answer is 'option 4).'
