Objectives of the MTEL Biology: Cell Biology Chapter
The MTEL Biology Exam is an assessment instrument that examines your comprehension of all elements of biology. A passing grade is necessary in order to obtain your teacher's license in the state of Massachusetts. The cell biology chapter is related to the Chemistry of Life and Cell Biology Objective of the exam, which includes 14% of the test questions. By taking the self-assessment quizzes, you can evaluate your level of comprehension and also experience the types of questions you will find on the actual exam.
The MTEL Biology Exam is a computer-based-test. There are 100 multiple-choice questions. These present you with a passage or question and ask you to select the correct response from several you are shown. There are also two open-response questions which evaluate your integration of knowledge and understanding in an essay format. The multiple-choice section counts for 80% of your score and the open-response for 20%.
1. Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane
If you want to make it through the day, you're going to need some energy. In this lesson, we'll learn about the organelle that supplies this energy, the mitochondrion, and why this cell structure appreciates the time you took to eat breakfast this morning!
2. Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores
In this lesson, we'll discuss the organization and importance of the nucleus in your cells. This is the membrane-bound structure responsible for containing all the genetic material essential to making you who you are.
3. The Fluid Mosaic Model of the Cell Membrane
In this lesson, we will discuss the components of the cell membrane and why the fluid mosaic model paints the best picture of its structure. We'll learn about the roles of the phospholipid bilayer, cholesterol, proteins and carbohydrates.
4. How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic
In this lesson, we will learn what gives phospholipids a dual personality. How can this molecule be both hydrophobic and hydrophilic, and why is this important to a cell?
5. Endocytosis and Exocytosis Across the Cell Membrane
In this lesson, we'll discover how some cells can eat, drink, and digest their dinner through the process of endocytosis and a structure called the lysosome. In addition, we'll learn how a cell can throw out the leftovers across the cell membrane during exocytosis.
6. The Ribosome: Structure, Function and Location
The ribosome is the cellular structure responsible for decoding your DNA. In this lesson, we'll learn about ribosome structure, function and location - characteristics that make it a very good genetic translator.
7. The Endomembrane System: Functions & Components
In this lesson, we'll learn about the endomembrane system, which consists of the endoplasmic reticulum and the Golgi apparatus. This system is important in making, packaging, and shipping all sorts of goodies for the cell to use!
8. The Cytoskeleton: Microtubules and Microfilaments
In this lesson, we'll learn about the cytoskeleton of your cells. This network of microtubules, intermediate filaments, and microfilaments helps different types of cells maintain a unique set of characteristics, including shape and movement.
