- Learn the functions of the male and female components of flowers.
- Take a look at some different methods of pollination.
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. Collenchyma Cells: Function, Definition & Examples
Plants contain numerous types of cells. All of these cells carry out specific functions. In this lesson, you will learn about the structure and function of collenchyma cells.
14. Conifers: Species, Types & Characteristics
Conifers are types of trees that produce pinecones as their reproductive structures. Learn more about the large variety of conifers in this lesson, after which you'll have the chance to take a short quiz.
15. Dicot: Cross Section, Definition & Plant Examples
Dicots are one of the two major types of flowering plants and are characterized by having 2-seed leaves, or cotyledons. In this lesson, you'll learn how to identify a dicot and explore some common examples.
16. Gibberellins in Plants: Definition & Function
Plants have hormones just like humans. Many plant hormones regulate growth and development. In this lesson, we will learn about hormones known as Gibberellins.
17. Parenchyma in Plants: Definition & Function
Plants contain numerous types of cells and tissues. In this lesson, you will learn about the function of a type of cell known as parenchyma that is commonly found in plants.
18. Sclerenchyma Cells: Function & Location
Plants contain a variety of cells that perform specific functions. In this lesson, you will learn about a type of cells known as sclerenchyma to gain an understanding of their function and location.
19. Taproot: Definition & Examples
Ever wonder why a plant or a tree doesn't just fall over in the wind? It is because a plant has a taproot. This lesson will explore the function and importance of a taproot.
20. Terminal Bud: Definition & Function
Plant growth can be very complex when you get into all of the cycles that occur during it. Like humans, a lot of the plant grows at once. In this lesson, we will discuss the terminal bud and what occurs there.
21. Amyloplast: Function & Definition
In this lesson, you will learn what an amyloplast is and its purpose in a plant cell. You will also learn a bit about its structure, what's inside it, as well as where it can be found. In addition, you'll learn about types of plastids and how they develop.
22. Balanced Chemical Equation for Photosynthesis
This lesson will go over the basics of photosynthesis and its chemical reaction, explaining how the chemical equation is formed and how it can be balanced.
23. Alfalfa: Definition, Uses & Benefits
This lesson is on the plant alfalfa. In this lesson, we'll go over what alfalfa is, how people use it, and some of the benefits to both other plants and humans.
