Correct option is D
The correct answer is: (D) the rate of respiration of Fruits is decreased
Explanation:
Fruits are preserved in cold storage because lower temperatures reduce the rate of respiration in fruits.
Respiration is a process in which fruits consume oxygen and release carbon dioxide, which causes ripening and decay.
By lowering the temperature, the metabolic processes (including respiration) slow down, which helps fruits stay fresh for a longer period.
Cold storage does not involve increasing humidity, oxygen, or darkness for preservation but mainly focuses on reducing the rate of respiration to delay the spoilage process.
Information Booster:
• Cold storage helps in maintaining the shelf life of fruits by slowing down the natural processes of ripening and spoilage.
• Respiration rate in fruits increases at higher temperatures, which speeds up the breakdown of sugars and other compounds, leading to quicker spoilage.
• Common fruits like apples, oranges, and strawberries benefit greatly from being stored in cold temperatures.
• Temperature control in cold storage ranges typically from 0 to 5°C for fruits.
• Cold storage also helps in preventing the growth of spoilage-causing bacteria and fungi.
Additional Information:
• Option A – Exposure to humidity is increased: Increased humidity can actually promote mold growth and spoilage rather than preserving the fruit.
• Option B – More oxygen is available: More oxygen would actually increase respiration and hasten ripening, which is counterproductive for preservation.
• Option C – Fruits are stored in a dark place: Darkness does not significantly impact the preservation of most fruits compared to the effects of temperature control.
