About This Chapter
TExES Life Science: Plant Biology - Chapter Summary
Each of this chapter's videos explore the life and characteristics of plants as well as their classifications and root systems. Get a fresh perspective on topics you studied in college, and perhaps learn something new. For instance, rediscover the role of nitrogen in plant development and learn to interpret cladograms. Review these and other subjects as you get ready to take the TExES Life Science examination. This chapter could assist you with:
- Classifying plants, and understanding the structure of stems and leaves
- Describing the apical meristem and the lateral meristem
- Understanding the structure of leaves, and identifying various kinds of roots and clades
- Discussing the importance of root growth and the significance of nitrogen to humans
- Explaining the processes of xylem and phloem
- Understanding the components of flowers as well as the processes of pollination and fertilization
This chapter's videos can serve as an extra study resource that prepares you to answer plant biology questions on the TExES Life Science examination. Instructors who have years of experience present the above concepts to help you remember facts you studied in college. If you have Web-ready technology, you can study anywhere and anytime it's convenient for you. Make use of the video tags to locate specific information or refer to the written transcripts. Your questions on plant biology may be submitted so that experts can answer them. The self-assessment quizzes will evaluate your progress.
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. Plant Stems & Shoot Systems
In this lesson, we'll explore plant stems, what their functions and structures are, and why they are important to a plant. We'll look at how stems grow and what shoots are.
3. 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.
4. Root Tissue & System Growth
Roots are out of sight and out of mind, but they are essential to plants. We'll explore the functions and structures of roots, and how they grow in this lesson.
5. 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.
6. 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.
7. 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.
8. Pollination Process: Male & Female Flower Components
In this lesson, we'll learn about the pollination process and the components in plants that make this possible. We'll also learn about the various forms of pollination and how they work.
9. Cladograms and Phylogenetic Trees: Evolution Classifications
Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.
