Question

a plant or animal that is phototropic grows or moves toward or away from light. what does the root trop mean? break or burst light turn or move carry

Explanation:

The term "tropism" in biology refers to the growth or movement of an organism in response to a stimulus. A root tropism would involve the root turning or moving in response to a particular stimulus (like gravity, water, etc.). The word "turn or move" best fits the concept of what a tropism (in this case root tropism) entails as it describes the directional change in growth/movement. "Break or burst" is more about physical rupture, "light" is a stimulus (but not the action of the tropism itself), and "carry" is about transporting something which is not relevant here.

Answer:

turn or move
