Question

This type of vegetable continues to grow after harvesting and it respires or ‘sweats’ in plastic bags.

• A. Pods
• B. Broccoli
• C. Fungi
• D. Tubers

Hint:

Tubers such as potatoes continue to respire after harvesting and require proper storage to prevent sprouting and sweating.

Answer 1

The Correct Option is D

The question asks which type of vegetable continues to grow and 'sweats' when stored in plastic bags. Let's analyze the options to understand why "Tubers" is the correct answer.

1. Pods: Pods, such as beans and peas, do not typically continue to grow after harvesting. They undergo a drying process when harvested for seeds.
2. Broccoli: Broccoli is a flower that doesn't continue to grow after being harvested. It may respire, but to a much lesser extent compared to tubers.
3. Fungi: Fungi like mushrooms do not grow after harvesting. They can decompose quickly but do not actively grow.
4. Tubers: Tubers, like potatoes and yams, continue to undergo metabolic activities after harvesting. They can sprout new growth points, hence showing growth activity. Tubers are known to 'sweat' or undergo respiration, releasing moisture and gases when sealed in plastic bags, which is a key point in the question.

Conclusion: Tubers are the type of vegetables that fit the criteria mentioned in the question. They grow after being harvested and show respiration activity that is evident when sealed in plastic. This continued metabolic activity is because tubers store energy in the form of starch, allowing them to sprout and grow under the right conditions.
