Question

the tops of bulb producing plants should be allowed to continue growing until they die naturally because they ______. a. continue to manufacture food for storage in the bulb b. shade the bulbs and keep them cool c. grow larger and provide extra compost for the bulbs d. add beauty to the flower garden

Explanation:

To solve this, we analyze each option:

• Option a: Bulb - producing plants (like tulips, daffodils) use their green tops (leaves) to perform photosynthesis, manufacturing food (sugars) that is stored in the bulb for next year’s growth. Allowing leaves to die naturally ensures this food - storage process is complete.
• Option b: The main role of bulb tops isn’t shading; bulbs are underground, and shading isn’t their primary function here.
• Option c: The tops don’t primarily provide compost; their main job is food production for the bulb, not composting.
• Option d: While they may add beauty, the biological reason for letting them die naturally is related to the bulb’s survival (food storage), not aesthetics.

Answer:

a. continue to manufacture food for storage in the bulb
