About This Chapter
TExES Life Science: Cell Communication - Chapter Summary
Take a look at how cells in living organisms communicate as you examine this chapter. Brush up on this and other biology topics while you get ready to take the TExES Life Science 7-12 test. At the end of this chapter, you should feel better equipped to answer questions related to the following:
- The entire cell communication process
- Signal reception
- How cells respond to signals
Many of you learned about cell structure quite some time ago during your introductory biology classes, so you may have forgotten parts of the process or specific key terms. Let our study guides shake up the receptors in your brain so that you can remember those lessons learned so long ago. Our instructors use entertaining visual effects combined with clear and concise audio voice-overs, producing an enhanced learning experience. You can even assess how well you are doing by taking the quizzes available at the end of each lesson. If you want to run some question-answer drills before taking the TExES Life Science 7-12 test, try your luck with our chapter exam questions.
TExES Life Science: Cell Communication Objectives
Before you can start teaching in the state of Texas, you must prove that you possess the proper training and field knowledge to teach students successfully. Life science teachers can verify their experience through the passing of the TExES Life Science 7-12 test. On this particular assessment, the 100 questions are all in the multiple-choice format, and individuals take these tests completely by computer at designated test locations. Questions on this comprehensive examination will address six key areas within the life science field. Most of the questions about cell communication will be found in the area about the processes and structures of cells. Questions within this major area contribute 20% to your final test score.
1. An Overview of Cell Communication
Cellular communication is an important process that allows cells to pass signals to one another. In this video lesson, you will be introduced to the process of cellular communication, identifying the three steps of cellular signaling in organisms.
2. Signal Reception in Cells
Our cells 'talk' to each other all the time through chemical signals. The first step of this process, reception, is a critical component. In this video lesson you will learn about this step in cell communication as well as understand its overall importance.
3. Transduction in Cells
Once a cellular signal is received, a chain of events begins that helps the receiving cell decode the signal. In this video lesson you will learn about this second step of cellular communication and its importance to the overall process.
4. Cellular Responses to Signals
After reception of a signaling molecule and movement of that signal through transduction, the cell can now respond. There are different types of cellular response as well as different mechanisms the cell uses to make this process more efficient.
