Demonstrating Osmosis practice exercise 4

A biology student places red blood cells into a beaker containing distilled water. After a while, the cells swell and burst. What explains this observation?

A doctor accidentally uses distilled water instead of a saline solution in an intravenous drip. Shortly after, the patient develops complications. Lab results show that the patient’s red blood cells have swollen and burst. What most likely caused this reaction?   (1 mark)

Study the image below showing two cassava sticks soaked overnight. Which one was placed in salty water and why?

During a home science activity, Achieng placed two identical cassava sticks into two bowls overnight. One bowl had salty water and the other had plain tap water. In the morning, one stick appeared soft and shrunken while the other remained firm. Study the image below and identify which stick was in salty water and explain why.   (1 mark)

During an experiment, a learner placed kale leaves in both plain water and salty water. One leaf was limp while the other remained crisp. What caused this difference?

During a kitchen experiment, Amani placed two fresh kale leaves into separate bowls—one with salty water and the other with plain tap water. After a few hours, one leaf became limp while the other remained crisp. What explains this observation?  (1 mark)

Why do mango slices become soft when stored in concentrated sugar solution for a long time?

A fruit vendor stores mango slices in a concentrated sugar solution to preserve them. After several hours, the mango slices become soft and shriveled. What is the most likely reason for this change?  (1 mark)
