Ch 23: Prentice Hall Biology Chapter 23: Roots, Stems, and Leaves

About This Chapter

The Roots, Stems, and Leaves chapter of this Prentice Hall Biology Textbook Companion course helps students learn essential biology lessons of roots, stems, and leaves. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Roots, Stems, and Leaves textbook chapter.

How it works:

  • Identify the lessons in the Roots, Stems, and Leaves chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the roots, stems, and leaves topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, re-watch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Plant cell structures
  • Root system growth
  • Structure of plant stems
  • Structure of leaves
  • Xylem
  • Phloem
  • Apical and lateral meristem

Plant Cell Structures: The Cell Wall and Central Vacuole

1. Plant Cell Structures: The Cell Wall and Central Vacuole

In this lesson, we'll talk about some of the things that make plant cells so different from our cells. In addition to being mean, green photosynthesizing machines, plant cells have cell walls and central vacuoles to make them unique!

Primary Root Tissue, Root Hairs and the Plant Vascular Cylinder

2. Primary Root Tissue, Root Hairs and the Plant Vascular Cylinder

Roots of plants can provide support, food and water. We will look at diagrams and photos to see the different parts of roots in order to explain these different functions.

Root System Growth: The Root Cap, Primary Roots & Lateral Roots

3. Root System Growth: The Root Cap, Primary Roots & Lateral Roots

It is easy to see some plants get taller, but it is important to know that plants must also have a strong support that we cannot always see. Root growth helps plants survive and can happen in two ways.

Structure of Plant Stems: Vascular and Ground Tissue

4. Structure of Plant Stems: Vascular and Ground Tissue

You can determine the age of a tree by looking at its rings. In this lesson, we will look at the basic structures of stems and explore what causes the rings in a tree trunk.

Apical Meristem & Primary Shoot System Growth

5. Apical Meristem & Primary Shoot System Growth

Just like humans, plants need to grow. In this lesson, you'll see how plant growth occurs at specific locations and how the height of the plant is increased.

Lateral Meristem & Secondary Shoot System Growth

6. Lateral Meristem & Secondary Shoot System Growth

Why do some plants experience a secondary growth? Why do some plants grow only in height but others grow in height and width? Discover the answers to these questions in this lesson.

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.

Xylem: The Effect of Transpiration and Cohesion on Function

8. 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

9. 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.
