Question

a plant is placed near a window. instead of growing straight up, the plant grows toward the window. what is this plant demonstrating? (1 point)
dormancy
thigmotropism
gravitropism
phototropism

Explanation:

1. Analyze each option:

• Dormancy: A period of inactivity in plants, not related to growth direction. Eliminate.
• Thigmotropism: Response to touch (e.g., vines wrapping around a pole). The plant is growing toward light, not touch. Eliminate.
• Gravitropism: Response to gravity (e.g., roots growing down, stems up). The plant is growing toward the window (light), not gravity. Eliminate.
• Phototropism: Plant growth in response to light. The plant grows toward the window (source of light), so this matches.

Answer:

D. phototropism
