Across 2. The movement of sugars and other food materials through the phloem. 8. A plant that has two seed halves. 9. The movement of water from an area of high concentration to an area of low concentration through a partially permeable membrane. 12. Shrinking of animal cells due to loss of water. 13. When a plant cell is held in shape by the water pressure in the vacuole. 15. The waxy layer on the top surface of leaves that reduces water loss. 17. The tissue that transports dissolved food substances up and down the plant. 18. The shrinking of plant cells that have lost water and the cell membrane has come away from the cell wall.

Down 1. Large rectangular cells in the leaf where most photosynthesis takes place. 2. The loss of water from plant leaves. 3. The green pigment produced by plants that traps light energy. 4. Part of a leaf that carries water to the cells. 5. Bursting of an animal cell due to water gain. 6. When a plant cell loses shape due to a drop in water pressure in the vacuole. 7. What happens to a plant that does not take in enough water. 10. A small pore on the underside of a leaf. 11. Two cells that control the opening and closing of a stoma. 14. The tissue that transports water and dissolved minerals up a plant. 16. A central hollow cavity allowing passage of water in the xylem.
