Begin the lesson with an engaging question: 'How do plants transport water and nutrients from the roots to the leaves?' This will pique students' curiosity about plant structures.

Internal Structures – Vascular Tissue
Learning Objectives
- Identify the external and internal structures of plants and describe their roles in plant function.
- Explain the function of vascular tissue in plants and differentiate between xylem and phloem.
- Describe how the arrangement of vascular tissue in roots, stems, and leaves supports plant function.
- Compare vascular and non-vascular plants, highlighting the differences in their structures and nutrient transport mechanisms.
Introduction and Hook
Introduce the concept of vascular tissue using a simple analogy, like comparing it to a network of highways transporting essential goods across a country.
Direct Instruction
Explain the roles of xylem and phloem in vascular plants, emphasizing their functions in transporting water, nutrients, and sugars.
Use the 'Vascular Plants' video to visually demonstrate how vascular tissues function like super highways, enhancing understanding of plant biology.
Guided Exploration
Facilitate a discussion on the differences between vascular and non-vascular plants, using mosses as an example of non-vascular plants.
Encourage students to observe and compare the arrangement of vascular tissue in roots, stems, and leaves using diagrams or plant samples.
Hands-On Activity
Conduct an experiment to observe the function of xylem using celery and food coloring. This hands-on activity helps students visualize water transport in plants.
Independent Practice
Assign students to create a diagram illustrating the flow of water and nutrients through the xylem and phloem in a plant.
Check for Understanding
Use a quick quiz or exit ticket to assess students' understanding of the functions of xylem and phloem in vascular plants.
Try the QuizReview and Reflection
Have students reflect on what they learned about vascular tissue and its importance in plant survival and growth.
Assessment and Extension
Assign the 'External Structures of Weeds' assessment to explore how external structures support plant survival, encouraging critical thinking and application of knowledge.
For further exploration, use the 'Do Plants Need Roots?' assessment to investigate the role of roots in plant survival.
