About This Chapter
NJBCT: Multicellular Organisms - Chapter Summary
Multicellular organisms have deep structures that can change as a result of nature or other outside influences. The lessons in the NJBCT review guide examine these factors and other changes on a cellular level to give you a preview of what to expect on the actual exam that you will take at the end of your biology class. Topics in this chapter will include the following:
- Examples of multicellular organisms
- Epithelium and tissues
- Mutagens, irradiation and DNA damage
- Types of diabetes
- Causes of cystic fibrosis
- The definition of lactose intolerance
- Biotechnology apps in genetics
- Internal malfunction diseases

1. 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.
2. 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.
3. Causes of Mutation and DNA Damage- Mutagens
Mutations, or changes in DNA sequences, are incredibly important in biology, from evolution and diversity to cancer and genetic diseases. But how do mutations happen? In this lesson, you'll learn about mutagens, which are chemicals that can cause mutations.
4. Causes of Mutation and DNA Damage- Irradiation
By now, you know what mutations are and what effects they can cause, but how do mutations happen? In this lesson, learn about one important cause of mutations, irradiation.
5. What is Diabetes? - Types & Symptoms
Diabetes is a chronic condition that affects millions of people across the world today. This lesson explains more about the different forms of diabetes and how they may be treated in order for a person to live a healthier life.
6. Cystic Fibrosis: Cause, Progression, and Treatment
This lesson will discuss a genetic disorder called cystic fibrosis as well as it how it affects the respiratory and digestive system, the ways by which it can be diagnosed, and treated.
7. Lactose Intolerance and the Major Disaccharides: Definition, Structure & Examples
Disaccharides are a class of sugar created by the combination of two monosaccharides. The three major disaccharides in your diet are maltose, sucrose, and lactose. In this lesson, you will learn about these disaccharides and a common digestive system disorder called lactose intolerance.
8. Biotechnology Applications in Medicine & Genetics
The word DNA is most commonly associated with criminal investigations but the applications of genetics run well beyond this one field as this lesson explains. Test your knowledge by completing the quiz at the end of the lesson.
9. Diseases Caused by Internal Malfunction
Some think of the body as a temple. But what you must know is that this temple can actually destroy you through one of many ways. Find out how internal malfunction can cause disease.
