- Eukaryotic and prokaryotic cells
- Membrane-bound organelles
- The transformation of energy within living organisms
- The components of a plant
- Animal reproduction and development
- Multicellular organisms, epithelium and tissues
The dashboard feature can serve as an organizational home for your learning, displaying your progress through the chapter and recent studying activity. You'll also find links there to relevant practice quizzes and additional courses you can check out as a way of supplementing your studies.
1. What is Cell Theory? - Definition & Parts
Cell theory is a fundamental theory in biology that makes generalizations about cells. This lesson will help you understand the three main principles of cell theory.
2. Eukaryotic and Prokaryotic Cells: Similarities and Differences
In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.
3. Membrane-Bound Organelles in Eukaryotic Cells
Eukaryotic cells have several types of organelles working inside them. In this lesson, we will examine the various types of membrane-bound organelles and their functions.
4. What is Respiration? - Definition, Process & Equation
Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration. At the end, you can test your knowledge with a short quiz.
5. Photosynthesis: Definition & Reactions
Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.
6. Energy and Life: The Transformation of Energy in Living Organisms
While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.
7. Maintaining Homeostasis: Importance & Examples
Have you ever heard of the term 'homeostasis'? In this lesson you will learn the definition of homeostasis and discover why maintaining it is so important to the life of any organism.
8. What are the Parts of a Plant?
Ever look at a plant and wonder what each specific part is? A plant has two basic plant parts: the shoot and root systems. In this lesson, you'll learn and be able to identify each individual plant part within the shoot and root systems.
9. Overview of Animal Reproduction and Development
At this stage in life, you likely know where babies come from. However, did you know that some animals can make clones of themselves and reproduce sexually too? In this lesson, you'll learn more about sexual reproduction and early vertebrate development.
10. 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.
11. What Are the Types of Diseases?
This lesson will focus on the different types of diseases that a person may develop or contract. We'll discuss the differences between acute, chronic, primary, secondary, local, and systemic diseases.
12. Disease Control & Prevention
This lesson will discuss the many different ways by which people can control disease. Everything from vaccination to sterilization and beyond will be mentioned so that you can better appreciate the large arsenal of tools at our disposal.
