About This Chapter
Below is a sample breakdown of the Plant Biology chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Plant classifications; plant stems; leaves||Dicot, vascular, nonvascular and monocot plants; vascular and ground tissue and tree rings; spongy, epidermis and palisade layers of leaves and functions of leaves|
|Tuesday||Primary and secondary shoot system growth; root system growth||Apical and lateral meristems, terminal buds, nodes, internodes and cambium; root cap, lateral roots and primary roots|
|Wednesday||Root tissue and nitrogen fixation||Root hairs and plant vascular cylinder; importance of nitrogen to plants and humans|
|Thursday||Xylem and phloem||How water travels through plants, cohesion and transpiration; cycle of how leaves use sugar for energy and a review of the pressure flow hypothesis|
|Friday||Flowers and pollination||Floral structure and purpose, male and female components; flower-pollinator relationship and pollination methodology|
1. Classification of Vascular, Nonvascular, Monocot & Dicot Plants
Plants may not seem like the most interesting things around, but they are definitely useful. In this lesson, we will explore the basic classification of plants and the unique characteristics of each group.
2. Structure of Plant Stems: Vascular and Ground Tissue
You can determine the age of a tree by looking at its rings. In this lesson, we will look at the basic structures of stems and explore what causes the rings in a tree trunk.
3. Apical Meristem & Primary Shoot System Growth
Just like humans, plants need to grow. In this lesson, you'll see how plant growth occurs at specific locations and how the height of the plant is increased.
4. Lateral Meristem & Secondary Shoot System Growth
Why do some plants experience a secondary growth? Why do some plants grow only in height but others grow in height and width? Discover the answers to these questions in this lesson.
5. Structure of Leaves: The Epidermis, Palisade and Spongy Layers
Leaves may look pretty in the fall when they are changing colors, but they also provide many necessary functions for plants. In this lesson, we will explore the structures and functions of leaves.
6. Primary Root Tissue, Root Hairs and the Plant Vascular Cylinder
Roots of plants can provide support, food and water. We will look at diagrams and photos to see the different parts of roots in order to explain these different functions.
7. Root System Growth: The Root Cap, Primary Roots & Lateral Roots
It is easy to see some plants get taller, but it is important to know that plants must also have a strong support that we cannot always see. Root growth helps plants survive and can happen in two ways.
8. Nitrogen Fixation: Significance to Plants and Humans
Almost 80% of our atmosphere is nitrogen, but we can't use it. We will look at how this unusable nitrogen is converted into a form we can use and why nitrogen is important to plants and humans.
9. Xylem: The Effect of Transpiration and Cohesion on Function
Roots absorb water and leaves release water, but how does water move up a plant? In this lesson, we will look at how this happens in vascular plants, including the importance of xylem, cohesion and transpiration in the process.
10. Phloem: The Pressure Flow Hypothesis of Food Movement
Leaves produce sugars and stems; roots and fruits use these sugars for energy. In this lesson, we will look at how these sugars move throughout vascular plants, including the importance of phloem and the pressure flow hypothesis in the process.
11. Flowers: Structure and Function of Male & Female Components
In this lesson, we'll look at the parts of a flower and learn their functions. These natural beauties provide indispensable services to the plants they adorn.
12. Methods of Pollination and Flower-Pollinator Relationships
Ever wonder why bees are attracted to specific flowers? We will look at why certain animals are drawn to certain plants and other methods of pollination in this lesson.
