About This Chapter

Use these lessons to get re-acquainted with the structure of plants and their functions. Our videos and quizzes can help you prepare for questions about these topics that you'll encounter on the ILTS Biology exam.

ILTS Biology: Plant Anatomy and Physiology - Chapter Summary

Use this chapter's lessons to review information about plant classifications, their structures and processes such as reproduction and transpiration. These videos present concepts you'll find on the ILTS Biology exam, including:

  • Classifying plants through phylogenetic diagrams
  • Comparing how male and female parts function in pollination
  • Describing root systems
  • Identifying the importance of nitrogen
  • Applying knowledge of transpiration in the xylem
  • Analyzing the flow of energy in the phloem
  • Differentiating between vascular and non-vascular plants
  • Exploring the importance of plant stems and shoots

You can watch these lessons anytime on a computer, smartphone or tablet. The lessons include video tags that let you jump back to specific points for review without having to re-watch the entire lesson. Lesson quizzes and a chapter exam test your knowledge, and you can print out a sheet of quiz questions to use for offline study.

ILTS Biology: Plant Anatomy & Physiology Chapter Objectives

Illinois requires passing the 125-question ILTS Biology exam as a condition of teacher certification in biology. The exam consists entirely of multiple-choice questions, so completing our multiple-choice lesson quizzes can give you experience taking a test in this format. There are six subareas on the exam, and questions on the material in this chapter are in the subarea that deals with life science.

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.
