Ch 36: Praxis Middle School Science: Plant Structures & Functions

About This Chapter

Prepare for your Praxis Middle School Science test with self-paced video lessons and quizzes that allow you to study plant structures and functions at your own place. Plant growth, pollination, and reproduction are just some of the topics covered in this chapter.

Praxis Middle School Science: Plant Structures & Functions - Chapter Summary

Whether you'd like to take another look at the differences between monocot and dicot plants or practice identifying male and female flower components, this chapter has lessons aligned with the Praxis Middle School Science test's topics on plant structures and functions that you need to review. Topics of instruction include:

  • Plant classifications
  • Shoot and stem systems
  • Leaf structure
  • Root system growth
  • Nitrogen fixation
  • Xylem and phloem
  • Flower pollination
  • Cladograms and phylogentic trees
  • Plant growth and life cycles
  • Asexual plant reproduction
  • Plant hormones
  • Tropisms

This chapter's animated videos and illustrated transcripts make it easy to memorize the components of plant shoots, stems, leaves, and vascular systems as well as the vocabulary terms associated with plant growth and reproduction. Self-checking quizzes are also included to help track your progress and familiarize you with test-question formatting.

Praxis Middle School Science: Plant Structures & Functions Chapter Objectives

Some states use scores on this Praxis exam to measure the subject-area knowledge of prospective middle school science teachers. Lessons in this chapter can prepare you for test questions found in the life sciences content domain, which includes roughly 24% of the exam's multiple-choice questions and one of three constructed-response questions. Plant structure and function topics up for discussion include vascular and nonvascular plant characteristics; root, stem, and leaf structures; plant reproduction; nutrient and water transport; and plant growth.

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.

A Review of Plant Life Cycles & Alternation of Generations

10. A Review of Plant Life Cycles & Alternation of Generations

Plants have a unique system of passing on genetic information. In this lesson we are going to check out the alternation of generations used by plants to keep their gene pools strong.

Asexual Plant Reproduction: Vegetative Propagation and Bulbs

11. Asexual Plant Reproduction: Vegetative Propagation and Bulbs

Not all plants make attractive flowers in order to reproduce. Some plants will not make seeds and pollen either. These plants have other ways to create new offspring. We will look at a few key methods of vegetative propagation.

Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

12. Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

Animals aren't the only things that can respond to the environment. While plants may seem inanimate at times, they, too, can respond to the environment in order to better survive.

How Daily & Seasonal Cycles Affect Plants

13. How Daily & Seasonal Cycles Affect Plants

Plants live on a planet with days and seasons, and that affects their behavior. Learn about the daily and seasonal cycles of plants, and see how much you've learned with a quiz.

Plant Hormones: Chemical Control of Growth and Reproduction

14. Plant Hormones: Chemical Control of Growth and Reproduction

We most often think of hormones as things that control our actions and development. However, even plants have these chemicals to help regulate growth and reproduction.
