About This Chapter
Who's It For:
Anyone who needs help learning or mastering cell biology material will benefit from the lessons in this chapter. There is no faster or easier way to learn cell biology. Among those who would benefit are:
- Students who have fallen behind in understanding cell biology
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about cell biology
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How It Works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Cell Biology & Mitosis 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 Cell Biology & Mitosis chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any cell biology question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students Will Review:
This chapter helps students review the concepts in a cell biology unit of a mitosis course. Topics covered include:
- The hydrophobic and hydrophilic nature of a phospholipid bilayer
- Fluid mosaic model of a cell membrane
- Anatomy of the cytoskeleton and nucleus
- Structure and physical features of chromosomes
1. How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic
In this lesson, we will learn what gives phospholipids a dual personality. How can this molecule be both hydrophobic and hydrophilic, and why is this important to a cell?
2. The Fluid Mosaic Model of the Cell Membrane
In this lesson, we will discuss the components of the cell membrane and why the fluid mosaic model paints the best picture of its structure. We'll learn about the roles of the phospholipid bilayer, cholesterol, proteins and carbohydrates.
3. 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.
4. Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores
In this lesson, we'll discuss the organization and importance of the nucleus in your cells. This is the membrane-bound structure responsible for containing all the genetic material essential to making you who you are.
5. How is DNA Organized into Chromosomes? - Structure & Function
Explore the structure of chromosomes and see how DNA fits inside the nucleus of the cell. In this lesson, you'll learn about histones, chromatin and nucleosomes.
6. Parts of a Chromosome & Their Roles
Learn all about chromosomes, including the different parts of a chromosome and the types of chromosomes in diploid organisms like humans. Learn the vocab used with chromosomes.
7. Lymphocytes: Definition, Functions & Types
Our bodies contain numerous types of cells. In this lesson, you will learn about a type of cell known as a lymphocyte. You will also gain an understanding of the types of lymphocytes, as well as their functions in the body.
8. What is an Aster in Cell Division?
In this lesson, we'll discuss asters and their role in mitosis and meiosis. We'll talk about what asters are made of, and how asters help your cell nucleus to divide.
