Students will review:
This chapter helps students review the concepts in a plant biology unit of a standard AP Biology course. Topics covered include:
- Classification of plants
- Structures of plant leaves and stems
- Root growth and tissues
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. Monocotyledon Plants: Examples, Definition & Pictures
One way that botanists classify plants is by examining their structures. In this lesson, we are going to learn about a group of plants known as monocotyledons to gain an understanding of their characteristics.
14. C3 Plants: Definition, Types & Examples
Plants have evolved specific adaptations to allow them to survive in harsh climates. One of these adaptations is the way in which the plant undergoes photosynthesis. This lesson will focus on C3 plants, which use the most basic type of photosynthesis.
15. Herbaceous Plants: Examples & Types
Did you know that a plant is not just a plant? There are specific categories of plants that are based on their general structure. In this lesson, you will learn how to identify a herbaceous plant and be provided with examples that you can find in the real world!
16. NADPH: Definition, Structure & Function
This lesson will explore NADPH--where it comes from, what it means, what it looks like, and how it works. It will further delve into the name NADPH as well as distinguish it from its almost identical twin NADH.
17. Nitrogenase: Structure, Role in Nitrogen Fixation & Activity
This lesson will define and explore the activity, structure and importance of the enzyme nitrogenase. You'll also learn about the nitrifying bacteria found in some of the foods you eat every day.
18. Petiole: Definition & Function
In some plants, the petiole is the part of the plant that connects the leaf to the stem of the plant. In this lesson, learn what a petiole is, and is not, while becoming familiar with some petiole plants and trees.
19. Phylogenetic Tree: Definition & Types
We'll explore the ways taxa are categorized into a visual diagram, known as a phylogenetic tree, as well as what information these 'trees' tell us about the evolutionary relationship between organisms.
20. Upper Epidermis of a Leaf: Function & Definition
The epidermis of a plant is often overlooked, but it's an important barrier between the elements and the other tissues. Here you'll learn about the structure and functions of the upper epidermis of a leaf.
21. Vegetative Propagation in Plants: Definition, Methods & Examples
Have you ever wanted to start a garden, but didn't know how to start growing certain plants? In this lesson you will learn about a few methods to start growing plants that all depend on vegetative propagation.
22. Meristematic Tissue: Definition & Function
Have you ever wondered if a plant grows from the top or the bottom? Or how it gets bigger around? In this lesson, we'll explore the role of meristematic tissue in plant growth.
