Ch 3: HiSET: Cell Biology

About This Chapter

Studying this HiSET Science test-prep chapter will give you a solid understanding of several cell biology topics, such as the functions of the endomembrane system. You can practice answering questions on this subject with the lessons' available self-assessment quizzes.

HiSET: Cell Biology - Chapter Summary

Plant cell structures and active transport in cells make up a few of the many main topics covered in the chapter's lessons that are designed to prepare you for the HiSET Science test. The effective combination of video and text lessons gives you multiple ways to become familiar with the material. You'll see these topics discussed in the chapter:

  • Phospholipid bilayer structure
  • The fluid mosaic model
  • Passive and active transport in cells
  • Endocytosis and exocytosis
  • Structure of ribosomes and the nucleus
  • Components of the endomembrane system
  • The cytoskeleton
  • Chloroplast and mitochondria structure
  • Plant cells
  • Viruses

Our professional instructors use a fun approach within the short videos and teach major concepts through animations and graphics. The video tags make navigating through these video lessons quick and easy.

HiSET: Cell Biology Objectives

The HiSET Science subtest has a time limit of 80 minutes and includes 50 multiple-choice questions. The information in this chapter will make you ready for any of the numerous questions that could be asked related to cell biology. These topics are part of the life science portion of the test, which makes up 50% of the total test questions. Prepare for questions on the structure and functions of cells through these engaging videos, and then practice answering questions that are similar to those you will encounter on the actual HiSET test.

How a Phospholipid Bilayer Is Both Hydrophobic and Hydrophilic

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?

The Fluid Mosaic Model of the Cell Membrane

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.

Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

3. Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis

A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and osmosis.

Active Transport in Cells: Definition & Examples

4. Active Transport in Cells: Definition & Examples

In this lesson, we'll learn how substances are transported across the cell membrane against the concentration gradient. This might seem like an uphill battle for the cell, but all it takes is a little chemical energy and a few integral membrane proteins to kick off some active transport!

Endocytosis and Exocytosis Across the Cell Membrane

5. 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.

Structure of the Nucleus: Nucleolus, Nuclear Membrane, and Nuclear Pores

6. 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.

The Ribosome: Structure, Function and Location

7. The Ribosome: Structure, Function and Location

The ribosome is the cellular structure responsible for decoding your DNA. In this lesson, we'll learn about ribosome structure, function and location - characteristics that make it a very good genetic translator.

The Endomembrane System: Functions & Components

8. 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!

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.

Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

10. Mitochondria Structure: Cristae, Matrix and Inner & Outer Membrane

If you want to make it through the day, you're going to need some energy. In this lesson, we'll learn about the organelle that supplies this energy, the mitochondrion, and why this cell structure appreciates the time you took to eat breakfast this morning!

Chloroplast Structure: Chlorophyll, Stroma, Thylakoid, and Grana

11. 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

12. 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

13. 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

14. 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.
