MCAS STE Biology: Classification & Evolution - Videos & Lessons

About This Chapter

The video lessons in this chapter will help you prepare for questions on the MCAS STE Biology exam by exploring the evolution of living organisms and the classification of living things.

MCAS STE Biology: Classification & Evolution - Chapter Summary

Prepare for the MCAS STE Biology exam by studying biological evolution and how we identify and classify living organisms and species. By the end of this chapter you will have explored:

Taxonomy: the classification of living things
How prokaryotes evolved including archaebacteria and eubacteria
Evolution of protists
How animals, plants and fungi have evolved over time
Methods of nutrition in the six kingdoms

The video lessons have been developed by professional educators to help you retain the information easily and effectively. Use the timeline below each video to help you quickly find a particular section of the lesson that you would like to review. Take the self-assessment quiz at the end of each lesson to apply your knowledge.

MCAS STE Biology: Classification & Evolution Chapter Objectives

The MCAS STE Biology exam is a standardized test given to high school students in Massachusetts. The exam assesses students' ability to meet the educational learning standards in biology established by the Massachusetts Curriculum Framework. The exam is scored based on five main content areas. The lessons in this chapter will prepare you for questions related to evolution and biodiversity, which account for 20% of the final score.

The exam contains 40 multiple-choice questions and 5 open-ended questions. The MCAS STE Biology exam is one of four Science and Technology/Engineering exams taken by high school students in Massachusetts. A score of 220 or higher is required on one of the four STE exams to qualify for graduation.

1. Taxonomy: Classification and Naming of Living Things

The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.

2. The Evolution of Prokaryotes: Archaebacteria and Eubacteria

The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.

3. The Evolution of Protists: Importance & Evolutionary History

Some organisms are very familiar. However, there are some that play vital roles in our lives that we don't even think about. We will look at a group of one of these unfamiliar kingdoms - protists.

4. The Evolution of Plants and Fungi: Characteristics & Evolutionary History

In early classification systems, plants and fungi were grouped together. While there are some similarities between these two kingdoms, there are some key differences that we will explore.

5. The Evolution of Animals: Importance & Evolutionary History

The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.

6. Modes of Nutrition in The Six Kingdoms

Learn about the six kingdoms that make up life on earth, and the different ways that they create energy to live. See how productively you've used your energy by taking a quiz.
