Worked Solution

Step 1: Leaves produce food via photosynthesis; this food must be sent to all parts (up and down) for energy. Step [2-9]: Roots absorb water from the soil; this water is transported upwards to the rest of the plant. Step [2-9]: Therefore, food moves from leaves to all parts, and water moves from roots to all parts.

Correct answer: Food: From leaves to all parts; Water: From roots to all parts
