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.

What is Bacteria? - Definition, Characteristics & Examples

2. What is Bacteria? - Definition, Characteristics & Examples

This lesson will introduce the Bacteria, a large and diverse group of microorganisms. We will examine several key characteristics, as well as a few commonly known examples of bacterial species.

Cyanobacteria: Definition, Characteristics & Species

3. Cyanobacteria: Definition, Characteristics & Species

Cyanobacteria are a phylum of Bacteria that produce oxygen during photosynthesis. This lesson will examine cyanobacteria and the role they played in establishing our oxygen-rich atmosphere.

Archaea: Definition, Characteristics & Examples

4. Archaea: Definition, Characteristics & Examples

There is an entire domain of life that is made up of single-celled organisms without nuclei. We're not referring to the Bacteria domain, however. In this lesson, we will examine the main characteristics of the least commonly known domain, the Archaea.

Kingdom Protista: Definition, Characteristics & Examples

5. Kingdom Protista: Definition, Characteristics & Examples

Learn about the requirements to enter Kingdom Protista, one of the five kingdoms of life. Discover and read about the organisms that can be found there.

What are Protozoa? - Definition, Characteristics & Examples

6. What are Protozoa? - Definition, Characteristics & Examples

Taxonomy is the realm of science that attempts to group similar organisms together, which is not always an easy task. In this lesson, we will examine the protozoa, a diverse group of organisms that didn't really fit anywhere else.

Contractile Vacuole: Definition & Function

7. Contractile Vacuole: Definition & Function

Contractile vacuoles are membrane-bound organelles that exist mainly in the cells of the kingdom Protista. In this lesson, we will examine their role and see some examples of organisms that have contractile vacuoles.

What is Algae? - Definition, Characteristics & Examples

8. What is Algae? - Definition, Characteristics & Examples

Plants are not the only organisms capable of carrying out photosynthesis. In this lesson we will look at algae and how an algal species can be differentiated from other organisms and microbes.

What are Fungi? - Types and Characteristics

9. What are Fungi? - Types and Characteristics

In this lesson, we will examine the group of organisms known as the fungi. This group includes the familiar organisms mushrooms, yeasts and molds. We will look at several major characteristics of fungi, as well as a few disease-causing fungi.

Nutritional Requirements for Cells: Elements & Roles

10. Nutritional Requirements for Cells: Elements & Roles

Cells need nutrition in order to get the required elements. Which specific foods provide specific elements, and what do those elements do in the cell? Read on to learn how cells use their food.

Growth Requirements for Microorganisms

11. Growth Requirements for Microorganisms

All living organisms have requirements in order to live, and this includes microbes. In this lesson, we discuss the physical, chemical, and gaseous growth requirements of microorganisms.
