8 Lessons in Chapter 3: The Parts of Cells: Homework Help
Endocytosis and Exocytosis Across the Cell Membrane

1. 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.

Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

2. Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

In this lesson, we'll explore the parts of the chloroplast, such as the thylakoids and stroma, that make a chloroplast the perfect place for conducting photosynthesis in plant cells.

Plant Cell Structures: The Cell Wall and Central Vacuole

3. Plant Cell Structures: The Cell Wall and Central Vacuole

In this lesson, we'll talk about some of the things that make plant cells so different from our cells. In addition to being mean, green photosynthesizing machines, plant cells have cell walls and central vacuoles to make them unique!

Eukaryotic and Prokaryotic Cells: Similarities and Differences

4. 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.

Viruses: Bacteriophage Lytic and Lysogenic Cycles

5. Viruses: Bacteriophage Lytic and Lysogenic Cycles

Viruses are generally not only our enemy but also the enemy of many other organisms. Bacteriophages are viruses that infect specific bacteria. In this lesson, we'll discuss their basic structure and infection cycle.

Nucleoid: Definition, Function & Structure

6. Nucleoid: Definition, Function & Structure

The nucleoid is the region of a prokaryotic cell that houses the primary DNA. This lesson briefly discusses the nucleoid and its characteristics and how it compares to the nucleus of the eukaryotic cell.

Rhizoids: Definition & Function

7. Rhizoids: Definition & Function

Plants use their roots to take in water and minerals. If you have ever pulled a plant from the ground, you may not have noticed that its roots are made of many parts. In this lesson we will examine a critical part of roots known as rhizoids.

What Is Mitochondria? - Definition & Functions

8. What Is Mitochondria? - Definition & Functions

What does a little thing inside of your cells have to do with bacteria, energy, money, and your body's life sustaining processes? Well, in one word, 'mitochondrion' is the answer! In this lesson, you will learn about mitochondria and their function.
