Ch 3: The Parts of Cells: Help and Review

About This Chapter

The Parts of Cells chapter of this Middle School Life Science Help and Review course is the simplest way to master the parts of cells. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of the parts of cells.

Who's it for?

Anyone who needs help understanding middle school life science material will benefit from taking this course. You will be able to grasp the subject matter faster, retain critical knowledge longer and earn better grades. You're in the right place if you:

  • Have fallen behind in understanding organelles or the parts of cells.
  • Need an efficient way to learn about the parts of cells.
  • Learn best with engaging auditory and visual tools.
  • Struggle with learning disabilities or learning differences, including autism and ADHD.
  • Experience difficulty understanding your teachers.
  • Missed class time and need to catch up.
  • Can't access extra science learning resources at school.

How it works:

  • Start at the beginning, or identify the topics that you need help with.
  • Watch and learn from fun videos, reviewing as needed.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Submit questions to one of our instructors for personalized support if you need extra help.
  • Verify you're ready by completing the Parts of Cells chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Parts of Cells chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any relevant question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

In this chapter, you'll learn the answers to questions including:

  • What are the parts of cells?
  • How does active and passive transport occur in cells?
  • What are the definitions of diffusion, osmosis and saturation?
  • How do eukaryotic and prokaryotic cells differ?
  • How do the processes of endocytosis and exocytosis differ?

8 Lessons in Chapter 3: The Parts of Cells: Help and Review
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.

Cell Membrane: Functions, Role & Structure

6. 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.

Cell Membrane Functions List & Flashcards

Cell Membrane Functions List & Flashcards

This flashcard set will introduce you to the cell membrane and its structure and function. All cells have cell membranes, which act as the border patrol of a town, only allowing certain things in or out.

What is Cytoplasm? - Definition & Functions

8. What is Cytoplasm? - Definition & Functions

Did you know your cells are filled with a thick fluid? Cytoplasm is an important part of your cells and serves several functions that are key to cellular health and productivity.
