SBI3UI – Unit 6: Plants: Anatomy, Growth, and Function – Lesson 6 Date:______________ Plant Structures Part I – The Shoot System Big Ideas in this lesson: Plants have developed specialized structures that allow them to obtain resources from their environment. The body plan of many flowering plants consists of two systems: the shoot system and the root system. Terminology in this lesson: _______________________________________________________________________________________________________ _______________________________________________________________________________________________________ _______________________________________________________________________________________________________ _______________________________________________________________________________________________________ Assignment for this lesson: a) Read and highlight the key information in the given passages, while colouring the structures being described. b) Read p. 535‐542 in your text. Add/integrate any new information or diagrams into your notes. c) List the important terminology learned in this lesson and answer the following questions! 1. List the important organs/structures of the shoot system. 2. What is a flower? 3. Which part of the plant is the terminal portion where growth occurs? 4. What will eventually become of the lateral bud? 5. What are the functions of the root system? 6. What is the structure and function of the leaf cuticle? Which cells are responsible for the production of the cuticle? 7. Describe the location, structure, and function of stomata (p.536 in your text gives more details). 8. Which cell types make up the mesophyll layer of the leaf? 9. Describe the cells of the palisade layer. How does the arrangement of the palisade layer maximize the energy and raw materials available to these cells? 10. Describe the cells of the spongy mesophyll. What gases can be found in the air spaces of the spongy layer? 11. What are the three “fluid‐conducting functions” performed by the veins of the leaf?
