  1. 4. The process of water evaporating from the stomata of leaves, helping to cool the plant and maintain moisture levels.
  2. 5. Vascular bundles within leaves that transport water, minerals, and sugars, providing support and structure to the leaf.
  3. 6. Small openings on the surface of leaves through which gases like carbon dioxide and oxygen are exchanged during photosynthesis.
  4. 7. The inner tissue layer of a leaf where most photosynthesis takes place, containing chloroplasts and a high concentration of cells.
  5. 9. The biochemical process in which plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen.

  1. 1. cells: Specialized cells surrounding stomata that control their opening and closing to regulate gas exchange and minimize water loss.
  2. 2. Organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures sunlight energy.
  3. 3. layer: The upper layer of mesophyll cells in a leaf adapted for photosynthesis due to its high density and exposure to light.
  4. 6. layer: The lower layer of mesophyll cells in a leaf with air spaces for gas exchange and interconnected for efficient circulation.
  5. 8. The outermost layer of cells in a leaf, often coated with a waxy cuticle to reduce water loss and protect against external threats.
