Ch 2: Structure & Function of Cells

About This Chapter

Study.com experts put together this chapter using short video lessons to discuss the subject of structure and function of cells. Studying these lessons will improve your understanding of multicellular organisms, cell membranes, proteins, the cytoskeleton, and other specific aspects of cells.

Structure & Function of Cells - Chapter Summary

We put together this chapter to enhance your knowledge of structure and function of cells. Look at information about major biological molecule elements, unicellular organisms, eukaryotic versus prokaryotic cells, and more. Improve your knowledge about topics covered in these lessons about:

  • Life's foundational elements
  • Nucleic acids, carbohydrates, proteins and lipids
  • Examples of multicellular organisms
  • Structure and function of the cell
  • Functions, role, and structure of the cell membrane
  • Cell organelles
  • Cytoskeleton
  • Functions and components of the endomembrane system

Each lesson comes with a quiz to assess your understanding of the material just covered. If you need to review anything, use the video transcript or use the timeline tool to go right to the section you want to replay. A test at the end of the chapter will verify you understand the important concepts.

The Foundational Elements of Life

1. The Foundational Elements of Life

Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.

Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

2. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.

Multicellular Organism: Examples & Definition

3. Multicellular Organism: Examples & Definition

Most organisms consist of only one cell and are invisible to the naked eye. Others, such as the rabbit, the bread mold and the pine tree, are made of many cells. Learn how to classify the multi-cellular organisms that inhabit our world.

Unicellular Organisms: Definition & Examples

4. Unicellular Organisms: Definition & Examples

Life takes a great variety of forms. This world is home to many simple organisms that live in a variety of environments. In this lesson, we will examine unicellular organisms to gain a better understanding of them.

Eukaryotic and Prokaryotic Cells: Similarities and Differences

5. 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

6. 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 Membrane: Functions, Role & Structure

7. Cell Membrane: Functions, Role & Structure

You are made up of trillions and trillions of cells, and each one is separated from its surroundings by a cell membrane. Learn about the structure and functions of the cell membrane in this lesson.

Organelles in Cells: Definition & Functions

8. 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.

The Cytoskeleton: Microtubules and Microfilaments

9. 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.

The Endomembrane System: Functions & Components

10. 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!
