About This Chapter
Plant Structures & Function- Chapter Summary
The chapter's brief video components cover information about plant structures and function. The types of topics you will encounter in this lesson include the reproduction of plants and leaves. The chapter's content covers the following topics:
- Basic classification of plants
- What is inside roots
- Function of leaves
- Different ways plants reproduce
- The role of xylem
- How the environment affects plants
- Ways the plant responds to the environment
The professional instructors effectively cover the topics that were listed above. Our video lessons are engaging, informative and last no longer than 10 minutes. There is a video timeline feature that has video tags which allow you to jump around the lesson to specific areas you want to focus on. Every video is paired with transcripts if you would prefer to read your lessons instead of watching them.
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. 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.
6. 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.
7. 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.
8. 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 this kind of stress. This lesson gives some examples of how this occurs.
9. Plant Responses to Mechanical Stimuli
Did you 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.
