PLANT TRANSPORT SYSTEM

1. Tiny openings on the leaf surface that allow gas exchange.
5. The plant system responsible for transporting water, minerals, and food throughout the plant.
6. Essential nutrients absorbed by the roots from the soil.
7. The vascular tissue found inside the phloem.
10. The gas released by plants during photosynthesis.
14. Supports the plant and transports water, minerals, and food.
17. The plant organ that usually contains chlorophyll.
18. The gas absorbed by plants for photosynthesis.
19. The upward movement of water from the roots to the leaves.
20. The simple sugar produced during photosynthesis.
21. The process by which water evaporates from the leaves.
23. The movement of water across a selectively permeable membrane.
24. The movement of food from the leaves to different parts of the plant.
26. The attraction between water molecules.
29. The arrangement of xylem and phloem within a plant stem or leaf.
30. Tube-like structures in the xylem that conduct water.

2. The attraction between water molecules and the walls of xylem vessels.
3. The continuous flow of water from the roots to the leaves.
4. The green pigment that absorbs light energy for photosynthesis.
8. Anchors the plant to the ground and absorbs water and minerals from the soil.
9. The process by which roots take in water and minerals.
11. The force that helps pull water upward through the xylem.
12. The movement of gases into and out of the leaf.
13. The vascular tissue found outside the xylem.
15. The vascular tissue responsible for transporting water and minerals.
16. The primary site where plants make their own food.
22. The process by which plants produce food using sunlight, water, and carbon dioxide.
25. Specialized cells that regulate the opening and closing of stomata.
27. The vascular tissue that transports food throughout the plant.
28. The source of energy needed for photosynthesis.
