- 3. leaves/stems grow toward light
- 4. a stimulus that comes from inside an organism (wilting in plants)
- 6. something that causes a response
- 7. a stimulus that comes from outside an organism (light, temperature, precipitation)
- 8. water in the cytoplasm exerts a force on the cell wall, pushing outward, this pressure in the cells allows the plant to stand upright
- 9. stems grow away from gravity, roots grow with gravity
- 11. plants stems and leaves responding to light
Down
- 1. roots grow toward water
- 2. plants roots responding to gravity
- 5. plant grows toward or away from pressure(a plants response to touch
