  2. 1. What Biome would this plant be able to handle?_______________ Desert Tropical rainforest Taiga Tundra

  3. 2. Which of these organelles in a leaf is most likely to appear green under a microscope? • A. Chloroplast • B. Mitochondria • C. Ribosomes • D. Lysosomes

  4. 3. Which statement is true and demonstrates plant systems working together? • a. Roots grow in all directions • b. A plant bends toward the coldest side of a room • c. Xylem cells contract and expand to allow oxygen to enter a leaf • d. The glucose created in the leaves is transported by the phloem to store energy

  5. 4. A good way for a plant to reduce water loss is • keep their stomata closed when possible • Stop producing the waxy cuticle on the upper leaf surface • Limit the upward flow of water through their xylem by allowing air in through the roots

  6. 5. The specialized leaf cells which close when there is limited available water are called • A. gradient cells • B. glucose cells • C. guard cells • D. Golgi cells

  7. 6. According to the diagram, plants seem to respond by producing flowersa. during short periods of darknessb. during long period of darknessc. light has no effect on flowering

  8. 7. Sometimes, tiny plastic particles can enter the ocean ecosystems due to negligent garbage disposal by humans. • How do these pellets affect marine organisms? • a. these pellets spoil the natural beauty of the ecosystem. • b. They sink to the bottom of the seafloor and raise the sea level • c. They can block the digestive systems of these organisms. • d. They dissolve and change water quality.

  9. 8. Which of the following is a description of an environmental change • A. goats eating to much grass from a field • B. above normal rainfall in an desert ecosystem • C. The ocean tides rising and falling • D. A small creek dries up every summer

  10. 9. The functional xylem and phloem transport systems in an oak tree are located in the perimeter of the tree , just under the outer bark. Deeper wood in the center of the tree has the remains of nonfunctioning xylem and phloem which has become hardwood. Cutting a ring approximately 6 inches deep into the perimeter of the tree would have which effect listed below? • A. The oak would not be able to stand up anymore. • B. The oak would use the hardwood to transport water and sugar. • C. The oleander would die due to loss of water. • D. The root would take over photosynthesis
