SC.912.L.14.7

1. SC.912.L.14.7 Relate the structure of each of the major plant organs and tissues to physiological processes.

2. Which of the structures in the diagram below identifies this cell as a plant cell rather than an animal cell?

3. Unlike animal cells, plant cells have a large central vacuole. How does a vacuole support plant structures? • It fills with liquid, creating pressure that helps to support the cell. • It releases materials into the air that decrease the weight of the cell. • It contains genetic information that controls the activities of the plant. • It forms a rigid substance called cellulose that supports the plant.

4. A sedge is a grasslike plant with fibrous roots, which are small, shallow roots that branch out from the base of the plant. Which of the following best explains how the structure of the roots helps the plant? • The plant gets its support from the roots, which serve as a kind of anchor. • The roots transport water between the stems and leaves of the plant. • The plant uses its roots to capture water that is close to the surface of the soil. • The roots allow for the exchange of gases the plant needs for photosynthesis.

5. Plants are composed of different organs, tissues and cells. Which are found only in vascular plants? • Gametes and leaves • Xylem and phloem • Stomata and guard cells • Flowers and spores

6. The drawing below shows a cross section of a plant leaf. How does the component marked “x” contribute to the survival of the plant?A. It allows the intake of minerals needed for plant growth.B. It allows the intake of gases needed for photosynthesis.C. It allows the intake of sunlight needed for ATP productionD. It allows the intake of sugars needed for plant reproduction

7. Which of these structures is responsible for transporting water from plant roots to the rest of the plant? • Chloroplast • Phloem • Stoma • Xylem
