Goal To review the concepts from Chapter 2. Reviewing Key Terms Fill in the blanks using a word from the list below. organs shoot differentiation gall epidermis root system meristem 1. The protects the inner tissues of the leaf. 2. Specialized cells form during, which is a stage of development in an organism s body. 3. cells can give rise to various specialized cells in an organism s body. 4. Roots, stems, and leaves are all plant. 5. A plant can be compared to a tumour in an animal. 6. An organ co-ordinates the functions of organs to do a complex job for an organism. 7. Plants have two organ systems: the system and the system. Knowledge and Understanding Fill in the blanks. 8. Multicellular animals can sometimes replace or repair tissues, but they cannot replace or repair. Plants are different; periodically they can replace or repair new leaves, stems and roots. 9. Like multicellular animals, plants are made up of organs, and those organs are divided into. In plants, the three main organs are made of tissues, including dermal, ground and tissue. 10. The cells in actively growing areas give off a chemical called, which is a plant. If there is an actively growing terminal bud, the chemical will lateral growth. 11. Match the terms on the left with the most appropriate terms on the right. xylem vessel leaf fibrous root epidermis root hair cell part of a cell tissue organ system
12. Name the structures in this sketch of a leaf cross section. A. D. B. E. C. F. 13. Which of the structures in question 12 is responsible for gas exchange and transpiration? 14. a. Fill in the missing components to complete the photosynthesis reaction. carbon dioxide + + light energy glucose + b. Which plant organelle is responsible for photosynthesis? 15. There is something wrong with the following sentence. Re-write it to make it correct. Root cells transport minerals from the soil to the xylem, which also helps to transport sugar from the soil.
16. Use the Venn diagram below to compare and contrast tap roots and fibrous roots. Consider their structures and functions, and where you are likely to find them. Thinking and Investigation 17. Your friend labelled the following graph incorrectly. What is the correct match of results and environmental conditions? Friend s graph analysis: A = control plant B = plant placed in front of fan C = plant placed in clear plastic bag Correct graph analysis: A = B = C =
18. This graph shows the number of stomata in the leaves of daisies collected in four different provinces. In which province would you expect the least and the greatest amount of rainfall? Write your answers directly above the correct provinces. 19. Why might a houseplant wilt if it is planted in a pot that is too small? 20. Using the table, compare and contrast the two specialized places where water passes through a plant. Organs where they are located Root Hairs Stomata Systems that they are associated with Direction that water flows (into the plant/ out of the plant) Other processes associated with structure
21. a. Describe the following tissues: Dermal: Ground: Vascular: b. You place a celery stalk in a beaker filled with water and food colouring. The strings on the outside of the stalk begin to take up the coloured water. What type of tissue do you think the strings are composed of? Communication 22. In this chapter, you learned to explain the links between specialized cells, tissues, organs, and systems in plants. Using your textbook and/or your notes, fill in the following table to help you visualize the organization of a typical flowering plant.
23. In this chapter, you learned how plants cells specialize to form different kinds of plant tissues. You also learned: 1. how water and nutrients enter a plant, and 2. how these substances are transported from the roots to the leaves. Find the best figure in chapter 2 to illustrate EITHER of these points. Identify the figure, sketch what it shows with your own drawing, and re-write a new, but accurate caption for the figure that illustrates the point. Figure: Illustrating: Point 1 Point 2 (circle one) New Sketch: New Caption: 24. A company is trying to market a new outdoor plant watering device. The device allows gardeners to directly add water to the soil. Why would the company claim that this method is more desirable than spraying plants with a hose? 25. Which of the following plants might you have to water more often? Explain why.
Application 26. In this chapter, you learned to describe how plant organs work together to meet the needs of a plant. Discuss the interactions and processes that are common to the four organs by filling in the chart. Need of the plant Captures sunlight for photosynthesis Obtains carbon dioxide for photosynthesis Obtain water for cellular functions Obtains minerals for cellular functions Provides structural stability Releases oxygen from photosynthesis Makes sugar to supply energy to all cells Stores excess sugar for future use Transports substances to where they are needed Organ(s) involved in meeting need Explanation of how it meets need Fill in the blanks. 27. When plants are overwatered, they may die, as the water takes the place of molecules that roots also take up in order to perform cellular respiration in the root cells. 28. Your friend has an unripened peach that he would like to eat as soon as possible. You tell him to put it in a paper bag because the peach will then be surrounded by the hormone that it produces, which will ripen it faster. 29. Humans are not the only organisms that consume fruits and seeds. Other organisms, like fungi such as molds, also require them. What can be done to store seeds and fruits for future consumption, and prevent mold rot? Where have you seen this practice? 30. You know that the best time to collect maple sugar sap is in the early spring. You insert a tap into a tree, but no sap flows. What could be wrong?
