Plant System

5. The plant's "solar panels" that capture sunlight and make food through photosynthesis.
7. When a plant keeps its internal conditions balanced and stable, like maintaining the right amount of water.
9. The above-ground parts of a plant, including the stem, leaves, and flowers.
11. The tissue that transports food (glucose/sugar) made in the leaves to all other parts of the plant.
12. Plant growth response to touch or physical contact.
14. Plant growth response to gravity (roots grow down, stems grow up).

1. The process where plants use sunlight, water, and carbon dioxide to make their own food (glucose/sugar) and release oxygen.
2. The plant's anchor that grows underground to absorb water and minerals from the soil.
3. The tissue that transports water and minerals from the roots up to the leaves.
4. Plant growth toward light.
6. The plant's transport system made of xylem and phloem that moves water and food throughout the plant, like highways inside the plant.
7. Plant growth toward water.
8. Tiny pores (like little doors) in leaves that open and close to let gases in and out and control water loss.
10. The plant's protective outer layer, including the leaf surfaces that guard against damage and water loss.
13. A plant's growth response or movement toward or away from something in its environment.
15. The plant's support structure and highway that holds the plant upright and transports water and nutrients between roots and leaves.
