About This Chapter
Cells & Organization - Chapter Summary
As you go through these lessons on cells, you can beef up your understanding of multicellular and unicellular organisms. You can also review how plant and animal cells are different. By the end of the chapter, you should be ready to:
- List the three main structures of all cells
- Recall four main tissue types of multicellular organisms
- Explain the hierarchical organization of multicellular organisms
- Discuss how organ systems work together in an organism
- Describe how plant cells are different from human cells
- List parts of the compound microscope and the light microscope
- Detail the process of preserving and staining microscope specimens
- Differentiate between an amoeba and a protist
- Recount how Euglena is classified by scientists
The engaging teaching style used by our educators can help you get up to speed on cells as living organisms in little time. A short quiz is available for each lesson to test your knowledge. You can also print the lesson quizzes and use them as convenient worksheets.
1. What are Cells? - Overview
All living organisms are made up of cells, but do you know what a cell is? In this lesson, you can learn about the three main structures that all cells contain and about the two major types of cells.
2. Multicellular Organism: Examples & Definition
Most organisms consist of only one cell and are invisible to the naked eye. Others, such as the rabbit, the bread mold and the pine tree, are made of many cells. Learn how to classify the multi-cellular organisms that inhabit our world.
3. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
4. Unicellular Organisms: Definition & Examples
Life takes a great variety of forms. This world is home to many simple organisms that live in a variety of environments. In this lesson, we will examine unicellular organisms to gain a better understanding of them.
5. The Hierarchical Organization of Multicellular Organisms
In this lesson, we'll be exploring the awesome organization of living things. If you've ever wondered how microscopic cells could possibly produce a living human being, this lesson is for you.
6. How Organ Systems Work Together
This lesson is going to discuss what an organ system is inside of an organism, such as an animal or plant. We will then look at a few examples of how organ systems work together inside of various organisms.
7. The Difference Between Plant and Animal Cells
While both plant and animal cells are eukaryotic and share many similarities, they also differ in several ways. Learn about the key differences between these two cell types in this lesson.
8. 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!
9. Introduction to the Compound Microscope: Parts & Uses
The compound light microscope is a useful tool in any biology laboratory. In this lesson, you'll be introduced to the parts of a compound microscope, as well as understand the function of each of those parts.
10. Light Microscope: Definition, Uses & Parts
Observation is an essential part of science, especially biology. Objects like bacteria, however, are too small to observe with the naked eye. For this reason, the light microscope has become an important and widely used tool for scientists.
11. How to Preserve, Stain & Mount Microscope Specimens
Microscopes are incredible tools for observing the tiniest of organisms. Here we will identify the types of slides that can be made and describe how to best preserve, stain, and mount specimens. At the end, you can test yourself with a brief quiz.
12. Amoeba Protist: Type & Description
In this lesson we will explore what makes a protist a protist and an amoeba an amoeba. We will also look at some unique characteristics of these organisms, such as their movement and their method of food consumption.
13. Euglena: Characteristics, Classification & Structure
This world is full of fascinating unicellular organisms. In this lesson, you will learn about a widely studied microorganism known as Euglena. We will examine its way of life and how it is classified by scientists.
