Across
  1. 3. provides support for the leaf and transports water, minerals, and food energy to the rest of the plant
  2. 4. aids to prevent water loss and provides an extra layer between the outside and inside of the leaf
  3. 8. transports water and nutrients from the soil to the stems and leaves. Also provides mechanical support and storage
  4. 9. reduce the amount of required energy for the breathing process and helps the plant save energy in extreme conditions
  5. 10. produces energy through photosynthesis which aid plant growth
  6. 12. protects plants against drought, extreme temperatures, UV radiation, chemical attack, mechanical injuries, and pest infection
Down
  1. 1. allows carbon dioxide to enter the leaf and for oxygen and excess water to leave the leaf
  2. 2. leaf cell type that forms a tight layer around the veins. It makes photosynthesis more efficient.
  3. 5. most of photosynthesis occurs here. these cells are close together to increase light absorption
  4. 6. regulate gas exchange and water loss between the plant and environment
  5. 7. allows for the interchange of gases needed for photosynthesis
  6. 11. control gas diffusion by regulating the opening and closing of stomatal pores
