About This Chapter

Brush up on plant biology concepts with the short and engaging video lessons in this chapter. Reviewing this subject area can enhance your studies for the ORELA Middle Grades General Science assessment.

Plant Biology: ORELA Middle Grades General Science - Chapter Summary

You can gain the insight you need to answer questions related to plant biology on the ORELA Middle Grades General Science assessment. Upon completion of this chapter, you will be ready for the following:

  • Understanding the classification of vascular, nonvascular, monocot and dicot plants
  • Describing the structure of leaves, including the epidermis and spongy layers
  • Examining nitrogen fixation and its significance to plants and humans
  • Sharing knowledge of xylem and the effect of transpiration and cohesion on function
  • Discussing phloem and the pressure flow hypothesis of food movement

Use the lessons to create a study guide specifically dedicated to plant biology, or add to your existing general science guide. Along with watching the videos, you can take advantage of lesson transcripts you can print and use for taking notes and highlighting key concepts.

Plant Biology: ORELA Middle Grades General Science Objectives

The ORELA Middle Grades General Science assessment is a computer-based test that gauges your comprehension of the subject area to ensure you're prepared to secure licensure and teach it in the middle grades classroom. It consists of 150 multiple-choice questions that are broken into four content domains. This chapter's topics are found in the life science content domain, which constitutes approximately 25% of the total assessment.

Ease the process of preparing for the exam by watching the lessons in this chapter. You can also access full video transcripts if you'd prefer a written version of the lessons. Self-assessment quizzes and a chapter exam are available to test your readiness to take the exam. All of these resources can get you closer to your goal of earning a passing score of 228 or higher on the assessment.

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.

Structure of Leaves: The Epidermis, Palisade and Spongy Layers

2. 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.

Nitrogen Fixation: Significance to Plants and Humans

3. 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

4. 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

5. 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.
