Ch 30: Plant Structure & Function

About This Chapter

The lessons included in this chapter are a great way to learn about the structure and function of plants. Watch these lessons to learn about different classifications and groups of plants as well see how plants grow, reproduce and respond to stimuli.

Plant Structure & Function - Chapter Summary

Plants are some of the most wide-spread and diverse organisms on Earth. If you would like to improve your understanding of the structure and function of plants, go through the online video lessons included here to review different aspects of plant anatomy, growth and reproduction.

As you progress though this chapter you can study how plant adapt and respond to stress and mechanical or environmental stimuli as well as see how they produce sugar. Learn how water moves up in a plant and see the reason some plants use flowers to reproduce. Some of the additional topics you can learn about include:

  • Vascular, nonvascular, monocot and dicot plants
  • Characteristics of gymnosperms and angiosperms
  • Structure and function of the roots, stems and leaves
  • Asexual reproduction in plants
  • Reproduction in flowering plants
  • Importance of the phloem and xylem
  • Primary and secondary growth in plants

Our lessons are taught by experienced instructors, all of whom having expertise in these specific topics from biology and botany. The chapter's online format provides you with an easy and convenient means of learning about these topics at your own pace and on your own schedule. When watching these videos, you can use the helpful video tags to keep track of the main points in each lesson. The chapter also contains complete transcripts of each video for you to print out and study on your own time. Your personal Dashboard can also be used to keep a track of your learning progress once you complete the chapter.

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.

Gymnosperms: Characteristics, Definition & Types

2. Gymnosperms: Characteristics, Definition & Types

In this lesson, we will explore gymnosperms, which are a unique group of plants that do not have bright flowers or seeds that are protected in fruit. We will examine types of them as well as their characteristics and the way they reproduce.

Angiosperms: Characteristics, Definition & Examples

3. Angiosperms: Characteristics, Definition & Examples

Flowering plants are also known as angiosperms. In this lesson, we will explore this vast group of plants to learn what sets them apart from other types of plants and how they survive.

Environmental Stimuli & Stress: Plant Adaptations & Responses

4. 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

5. 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.

Roots & Stems: Structure & Function

6. 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

7. 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

8. 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.

Flowering Plants: Reproduction & Fertilization

9. 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

10. 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

11. 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.

Primary Growth of Plants

12. 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

13. 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.
