Ch 38: Understanding Plant Structures & Function

About This Chapter

We can help you fully understand plant function and structures with this chapter of helpful and user-friendly video lessons. You can study for an important exam or complete a challenging homework assignment with our mobile-friendly tools, accessible 24 hours a day.

Understanding Plant Structures & Function - Chapter Summary

Our informative chapter outlines topics related to plant structures and function. These lessons cover the classification of different kinds of plants, the function and structure of roots and stems and the structure of leaves, plus much more. Once you complete this chapter, you should be ready to:

  • Discuss the advantages and disadvantages of asexual plant reproduction
  • Outline the primary growth and secondary growth of plants
  • Analyze the fertilization of flowering plants
  • Explain the pressure flow hypothesis of food movement
  • Provide an explanation of and definition for xylem
  • Detail plant response and adaptation to environmental stress and stimuli
  • Describe how plants respond to mechanical stimuli

These video and text lessons have been created by expert instructors so they're easy to understand and thoroughly cover these topics. You can watch an entire video lesson for review or use the video tabs feature in the Timeline to skip to a specific section you'd like to see. The quizzes that accompany all the lessons, plus the chapter test, are a great way to prepare for an exam or ensure you're ready to move on.

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.

Roots & Stems: Structure & Function

2. Roots & Stems: Structure & Function

You have probably pulled a plant out of the ground by its stalk (stem) to reveal the jumbled mess of roots below, but do you know how roots and stems help a plant stay alive? Learn what is inside roots and stems and what they do.

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.

Asexual Reproduction in Plants: Advantages, Disadvantages & Types

4. Asexual Reproduction in Plants: Advantages, Disadvantages & Types

Plants are successful because they have evolved to have a variety of ways to reproduce. In this lesson, we will examine asexual reproduction in plants to learn the types, as well as the pros and cons of this means of reproduction.

Primary Growth of Plants

5. Primary Growth of Plants

In this lesson, you'll learn about how a plant grows taller and how this is different from a plant growing wider. You'll also learn about the types of tissues produced during primary growth and the functions of those tissues.

Secondary Growth in Plants

6. Secondary Growth in Plants

Secondary growth allows woody plants to grow very tall and strong. Growing outward as well as upward provides structure, support, and protection to these plants that they would not otherwise have.

Flowering Plants: Reproduction & Fertilization

7. Flowering Plants: Reproduction & Fertilization

Some plants use flowers to reproduce. The flowers contain all the parts needed for the reproduction process. This lesson explains how all of these parts are used to create the next generation of flowering plants.

Phloem: The Pressure Flow Hypothesis of Food Movement

8. 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.

Xylem: The Effect of Transpiration and Cohesion on Function

9. 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.

Environmental Stimuli & Stress: Plant Adaptations & Responses

10. Environmental Stimuli & Stress: Plant Adaptations & Responses

Plants get stressed out about a lot of stuff, like floods, droughts, high heat, and cold. And they have ways in which they deal with these kinds of stress. This lesson gives some examples of how this occurs.

Plant Responses to Mechanical Stimuli

11. Plant Responses to Mechanical Stimuli

Did you know that animals are not the only living things able to respond to touch? Plants have a sense of touch. Actually, plants respond to all sort of mechanical stimuli, as this lesson explains.
