______6. Cellular organelle in which photosynthesis takes place

______7. Products of photosynthesis

______8. Storage form of glucose in plants

______9. Lower, middle portion of leaf that contains loosely packed cells to allow for gas exchange

______10. Specialized vascular tissue that transports glucose in plants

______11. Vascular plant with fruit and flower

______12. Epidermal cells that regulate the size of the opening to allow for for the exchange of O2 & CO2.

______13. Type of root that has many secondary branching roots close to the surface of the soil

______14. Name of the structure that attaches a leaf to the main stem

______15. Means “naked seed”; seeds not protected in fruit

______16. Tiny extensions of epidermal cells that increase the surface area for absorption of water

______17. Waxy covering on the outside of leaves to prevent water loss

______18. Upper, middle portion of leaf that contains columnar cells with an abundant number of chloroplasts for photosynthesis

______19. Openings in the underside of the leaf that allow for gas exchange

______20. Organism that produces its own food

______21. Large main primary root that extends deep into the soil

IV. Fill in the Blank & Multiple Choice

40. ______Hormone that stimulate ripening of fruit.

41. ______Plant response of growing toward light.

42. ______Hormone that produces a dramatic increase in size, particularly in fruits and stems.

43. ______Plant’s response to gravity – makes roots grow down and stems grow up.

44. ______Hormone that stimulates cell division in roots and developing seeds.

45. ______Plant response that allows an ivy plant to attach to the side of a house and grow on it.

______46. Copper is a micronutrient that can be found in soil. Copper is important for reproductive growth in plants and plays an

indirect role in chlorophyll production. Which statement correctly describes the interaction that occurs between the root and

the shoot systems of plants to allow reproduction to occur?

  1. Copper is produced in the roots when copper-containing compounds are hydrolyzed.
  2. Copper that is absorbed by the roots is transported to reproductive tissues by the shoot system.
  3. The shoot system stores copper for later use by the roots and the reproductive structures.
  4. The shoot system transports copper to the roots after it is taken in through stomata in the leaves.

______47. Changes in water pressure within guard cells cause the cells to open or close the stoma. This response helps the plant

maintain homeostasis by —

  1. stabilizing the plant’s temperature through the evaporation of water
  2. regulating the amount of water the plant loses during transpiration
  3. allowing oxygen needed for photosynthesis to enter the plant
  4. enabling the plant to release more carbon dioxide at night for photosynthesis
