4. The pair of cells that control the opening and closing of a stoma
7. The carbohydrate used to build plant cell walls
8. The loose layer of leaf cells with air spaces for gas diffusion
10. The process that releases energy from glucose in cells
11. The vascular tissue that transports sucrose and amino acids
