Worked Solution
Step 1: Plants produce food (sugary liquid/glucose) during photosynthesis.
Step 2: This food is transported throughout the plant via the food-carrying tubes (phloem).
Step 3: The aphid must piece these specific tubes to access the sugary liquid.
Correct answer: The food-carrying tube
