Ch 17: MTEL Adult Basic Education: Life Science Concepts

About This Chapter

Make the information in our Life Science Concepts chapter part of your review process for the MTEL Adult Basic Education exam. You will find our video lessons and the accompanying quizzes to be excellent preparation for the exam.

MTEL Adult Basic Education: Life Science Concepts - Chapter Summary

Review the interrelationships between living things and their environmental surroundings through the information presented in these video lessons. From cell to organism to ecosystem, every aspect of life connects with and builds upon the next. If you want to prepare for the MTEL Adult Basic Education exam, you will find the following information in the videos useful:

  • The definition and explanation of living organisms
  • Ecosystems, trophic levels and food chains
  • Cells and the cell cycle
  • Genetics and chromosome theory
  • Evolution and natural selection
  • Definition and explanation of ecology

Pinpoint your review to the exact section of a video that you want to see by using the timeline. This handy feature allows you to proceed directly to any part of a video that you like without having to replay the lesson in its entirety. You can skip sections that you already know and concentrate directly on areas in which you require additional study. To further maximize your time, each of our lesson quizzes contains links that can connect you instantly back to the lesson.

MTEL Adult Basic Education: Life Science Concepts Objectives

The lessons in our Life Science Concepts chapter align with objective 0014 of Subarea V: Science on the MTEL Adult Basic Education exam, which is a required part of the teacher licensure process. There are from 9 to 11 questions on this part of the exam. Subarea V makes up 10% of the overall score on the test.

The MTEL Adult Basic Education exam is computer-based. You will have 100 multiple-choice questions to answer and two open-ended responses to write. You must complete both of the latter. You will be required to compose articles from the topics given, and each should be between 150 and 300 words in length.

The Defining Characteristics of Living Organisms

1. The Defining Characteristics of Living Organisms

A house is not a living thing, but the people, animals, and plants living inside it are. So how do we define 'life'? Learn about seven characteristics that all living organisms have in common, no matter how different they may look on the outside.

What Is an Ecosystem? - Definition & Explanation

2. What Is an Ecosystem? - Definition & Explanation

Similar to a car engine that is made up of multiple parts working together, an ecosystem has interacting parts that support a whole. But how do we define an ecosystem and what are the components they consist of?

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

3. Food Chains, Trophic Levels and Energy Flow in an Ecosystem

In this lesson, you'll learn about food chains, food webs, and the different roles that organisms play in an ecosystem. You'll also learn about how energy flows through an ecosystem.

The Cell: Structure & Function

4. The Cell: Structure & Function

The cell is a small, but complex structure. Take a look inside the outer plasma membrane of a cell and discover the functions of some common cellular components, including the nucleus, endoplasmic reticulum, Golgi apparatus and mitochondria, in this lesson.

The Cell Cycle: Definition, Phases & Sequence

5. The Cell Cycle: Definition, Phases & Sequence

Learn about the dividing and non-dividing states of the cell and discover the different phases of the cell cycle, including interphase, cytokinesis, and the stages of cell division.

Genetics: Heredity, Traits & Chromosomes

6. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

The Chromosome Theory of Inheritance: Segregation and Independent Assortment

7. The Chromosome Theory of Inheritance: Segregation and Independent Assortment

Mendel proposed the law of segregation and the law of independent assortment to explain the inheritance behind his pea plant traits. A hundred years later, Boveri and Sutton developed the chromosome theory of inheritance, which stated that chromosomes were responsible for the heredity Mendel observed. Learn about these men and their ideas in this lesson.

Theories of Evolution: Lamarck vs. Darwin

8. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

Natural Selection & Adaptation: Definition, Theory & Examples

9. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

What Is Ecology? - Definition & Explanation

10. What Is Ecology? - Definition & Explanation

From the largest animals to bacteria invisible to the human eye, the survival of any organism depends on its interaction with the environment. In this lesson you will learn the basics about ecology, the scientific study of these interactions.
