Fruits stored in a cold chamber exhibit longer storage life because

aexposure to sunlight is prevented
bconcentration of carbon dioxide in the environment in increased
crate of respiration in decreased
dthere is an increase in humidity
✓ Correct answer: c) rate of respiration in decreased
ExplanationAfter harvest, fruits and vegetables remain metabolically active, with respiration being a key manifestation of this activity.Respiration involves the breakdown of stored nutrients to release energy for cellular processes.This process can be effectively slowed by lowering the temperature, which decreases the metabolic rate.Since harvested fruits and vegetables are no longer connected to the plant’s roots, they cannot acquire additional nutrients.As a result, they rely entirely on their stored nutrients for energy.Once these reserves are depleted, the produce begins to degrade.Therefore, controlling the rate of respiration through proper storage conditions, such as refrigeration, is crucial to preserving fruits and vegetables for longer periods and maintaining their quality.190
