Ch 17: AP Biology - Plant Biology: Homework Help

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. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. Nitrogen Fixation: Significance to Plants and Humans

Almost 80% of our atmosphere is nitrogen, but we can't use it. We will look at how this unusable nitrogen is converted into a form we can use and why nitrogen is important to plants and humans.

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. 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.

11. Flowers: Structure and Function of Male & Female Components

In this lesson, we'll look at the parts of a flower and learn their functions. These natural beauties provide indispensable services to the plants they adorn.

12. Methods of Pollination and Flower-Pollinator Relationships

Ever wonder why bees are attracted to specific flowers? We will look at why certain animals are drawn to certain plants and other methods of pollination in this lesson.

13. C4 Plants: Definition, Types & Examples

After exploring this lesson, you'll be able to define and identify C4 plants. Learn about what a C4 plant is and what makes C4 plants unique. Then you can test your knowledge with a quiz.

14. Cambium: Definition & Function

Do you know the definition of cambium? If not, this lesson is just for you! It defines and explains the importance and function of the cambium in plants, as well as identifies the various types of cambium.

15. Plant Meristem: Definition & Function

Plants and humans are more alike than you think! They both grow, for one thing. Find out how plants grow and learn where this process is similar to growth in humans.

16. Primary Consumers: Definition & Examples

Learn all about primary consumers and become familiar with some examples of them. After reading the lesson, the quiz will test your knowledge of primary consumers and your ability to recognize examples.

17. Rhizomes: Definition & Examples

Have you ever eaten a rhizome? Would you know if you had? In this lesson, learn more about what rhizomes are. You will also discover which common plants have rhizomes.

18. Short-Day Plants: Examples & Explanation

All plants require light to grow and develop, though some plants don't require as much light as others. In this lesson, we'll examine a group of plants known as short-day plants.

19. Turgor Pressure in Plants: Definition & Overview

In this lesson, you will learn about the structure of plant cells and how the pressure inside is crucial for the plant's ability to grow and stand tall.

20. What is Lichen Planus? - Causes, Symptoms & Treatment

Lichen planus is a skin condition that can look and feel uncomfortable. In this lesson, we will explore lichen planus, including the causes, symptoms, and treatment.
