Question

Assume you are growing a bacterial culture in a glucose medium. your lab partner adds more glucose in hopes of speeding up the experiment. the bacteria suddenly die. the best explanation for this result is that __________.

Answer 1

Bacterial cells died because they plasmolyzed. when higher amount of glucose was added in the medium, the medium became hypertonic in comparison to plasma of the bacterial cells. As a result, water moves from the cells to medium by osmosis making the cells to shrink and lose their normal functioning which cause their death.
