Ch 41: TExES Science 7-12: Plant Biology

About This Chapter

Gain insights into the secret life of plants while you prepare for the TExES Science 7-12 exam. Take a closer look at how plants grow, the processes involved in food and water intake and more in the Plant Biology chapter of this study guide.

TExES Science 7-12: Plant Biology - Chapter Summary

The lessons in this chapter examine the biology of plant life with emphasis on plant structure and processes, tissue systems and growth, and evolutionary classification diagrams. As you study for the TExES Science 7-12 test, you can incorporate this material into your body of knowledge so that you are better prepared for the types of questions you may encounter on the exam. You will review the information shown in the list below:

  • Monocots, dicots, vascular and nonvascular plants
  • Plant systems: roots, stems and shoots
  • Composition and structure of leaves and roots
  • Importance of nitrogen fixation
  • Role and properties of xylem and phloem
  • Processes and structures involved in pollination
  • Evolutionary classification charts: cladograms and phylogenetic trees

The transcripts that mirror each of our video lessons include key vocabulary such as scientific terminology, taxonomic terms and more in boldface type so that you can see and refer to it immediately. The short duration of each lesson enables you to move through the study guide quickly, while readily accessible instructors and subject-matter experts are available to answer questions or provide such assistance as you may require.

Classification of Vascular, Nonvascular, Monocot & Dicot Plants

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.

Plant Stems & Shoot Systems

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.

Structure of Leaves: The Epidermis, Palisade and Spongy Layers

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.

Root Tissue & System Growth

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.

Nitrogen Fixation: Significance to Plants and Humans

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.

Xylem: The Effect of Transpiration and Cohesion on Function

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.

Phloem: The Pressure Flow Hypothesis of Food Movement

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.

Pollination Process: Male & Female Flower Components

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.

Cladograms and Phylogenetic Trees: Evolution Classifications

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.
