About This Chapter
Plant Biology and Structure - Chapter Summary and Learning Objectives
Demystify plant biology and structure in this series of lessons led by a qualified life science instructor. Learn about different kinds of plants and their parts. Find out more about how plants function, how they pollinate, and what their benefit is to other plants and people. At the end of this chapter, you should be able to:
- Define two kinds of classifications of plants
- Describe the structure of a leaf
- Describe the structure of roots and stems
- Explain nitrogen fixation and why it's important
- Describe how male and female flowers differ
- Explain how pollination happens
|Classification of Vascular, Nonvascular, Monocot, and Dicot Plants||Describe the physical characteristics that differentiate a vascular plant from a nonvascular plant, and a monocot plant from a dicot plant.|
|Structure of Leaves: The Epidermis, Palisade, and Spongy Layers||Identify the parts of a leaf, and discuss their characteristics.|
|Roots and Stems: Structure and Function||Describe what roots and stems are and how they work.|
|Nitrogen Fixation: Significance to Plants and Humans||Describe the process of nitrogen fixation and why the capture of free nitrogen matters matters to living things.|
|Flowers: Structure and Function of Male and Female Components||Discuss the parts of flowers, and identify the differences among male and female plants.|
|Methods of Pollination and Flower-Pollinator Relationships||Name the methods by which pollination can occur, and describe the relationship between typical pollinators and flowers.|
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 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.
3. 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.
4. 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.
5. 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.
6. 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.
