Ch 6: Cell Size, Structure & Function

About This Chapter

Find out more about the size, function and structure of cells with these video and text lessons. These lessons can help you with test prep, homework or classwork assignments, or you can use them to increase your general science knowledge.

Cell Size, Structure & Function - Chapter Summary

In this chapter, you'll take an in-depth look at the organelles inside a cell and examine how to describe the volume, surface area and scale of cells. You'll also look at the differences between prokaryotic and eukaryotic cells and find out whether or not bacteria have organelles. By the time you've completed this chapter, you should be able to do the following:

  • Discuss biology as the study of living things
  • Explain what cells are
  • Compare and contrast prokaryotic and eukaryotic cells
  • Examine the structure and function of the cell
  • Describe the scale and size of cells with regard to volume, organelles and surface area
  • Identify the definition and functions of organelles and whether or not they're present in bacteria
  • Use microscopes and micrographs to identify organelles

This comprehensive study guide uses text and video lessons that are interesting and informative despite their short length. Lesson quizzes and a test at the end of the chapter allow you to check your retention of the material, and our experts are here to help you with any questions you might have.

Eukaryotic and Prokaryotic Cells: Similarities and Differences

1. Eukaryotic and Prokaryotic Cells: Similarities and Differences

In this lesson, we discuss the similarities and differences between the eukaryotic cells of your body and prokaryotic cells such as bacteria. Eukaryotes organize different functions within specialized membrane-bound compartments called organelles. These structures do not exist in prokaryotes.

The Cell: Structure & Function

2. 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.

Cell Size & Scale: Surface Area, Volume Ratio & Organelles

3. Cell Size & Scale: Surface Area, Volume Ratio & Organelles

In this lesson, we'll be explaining the limitations of cell size, specifically the surface area to volume ratio. Then, we'll look at organelles that help cells overcome these limitations.

Organelles in Cells: Definition & Functions

4. Organelles in Cells: Definition & Functions

This lesson will focus on the major organelles that are found inside eukaryotic cells. It will discuss their structures and functions. The differences in organelles found in plant and animal cells will also be covered.

Do Bacteria Cells Have Organelles?

5. Do Bacteria Cells Have Organelles?

Bacteria are inside of you, but what is inside of them? This lesson discusses the internal structure of bacteria and whether or not they have organelles.
