  4. 8. An environmental factor where increasing the brightness of a lamp causes a plant to produce food faster.
  5. 9. The tiny cell structure in a plant cell that contains the green pigment needed to make food.
  6. 10. The form of energy that flows through a closed circuit to operate appliances like fans or lamps.
  7. 15. A term used to describe any object or component that provides or gives out a form of energy.
  8. 19. Stored energy found in a stretched rubber band or a compressed metal spring.

  1. 1. The form of energy from a lamp or the sun that green plants need to carry out food production.
  2. 2. The green pigment found in leaves that is essential for absorbing light during food production.
  3. 3. The process where green plants use light, carbon dioxide, and water to produce sugar and release a gas.
  4. 5. Stored energy possessed by an object due to its high position above the ground.
  5. 6. The form of energy possessed by any moving object, like a running child or a rolling marble.
  6. 11. An object or material that takes in or absorbs a form of energy from its surroundings.
  7. 12. Chlorophyll is required in leaves to __________ from the sun so the plant can carry out photosynthesis.
  8. 13. The primary natural source of light energy that plants use to make food during the day.
  9. 14. The process where energy changes from one form to another, such as stored energy in food becoming movement energy.
  10. 16. A basic need absorbed by roots from the soil to be used as a raw material for food production.
  11. 17. Unlike fungi, green plants can __________ because they possess a specific green pigment to capture sunlight.
  12. 18. Tiny openings located mostly on the underside of a leaf that allow gases to move in and out.
  13. 20. The gas released by green leaves into the surroundings as a byproduct during food production.
