About This Chapter
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
