About This Chapter
1. Channel Protein: Definition & Function
In this lesson, you will learn the definition of a channel protein, as well as how those proteins assist in transporting material across the cell membrane. Afterwards, test your understanding with a quiz.
2. Aneuploidy: Definition & Disorders
This lesson will define aneuploidy, what it is and what it means. The lesson will also identify some of the disorders associated with aneuploidy and how they come about.
3. Gametogenesis: Definition & Concept
Birds do it, bees do it, even educated fleas do it. Let's do it, let's make some gametes. This lesson discusses how sperm and egg are produced and why these cell types are different from any other cell in your body.
4. The G0 Phase of the Cell Cycle
What are the parts of the cell cycle? In which part of the cycle does a cell spend most of its time? In this lesson you will learn about the G0 phase of the cell cycle and why it is so important to the overall health of an organism.
5. What is Apoptosis? - Definition, Pathway & Examples
This lesson will discuss apoptosis, giving a definition and overview of importance. It will also delve into a few of the pathways by which apoptosis occurs and give some examples of when apoptosis is induced.
6. Can a Cell Have More Than One Nucleus?
We often think of cells as having specific parts, and often times, they need to adjust their components to do their jobs properly. This lesson will discuss cells that have extra nuclei.
7. Do Cnidaria Have Germ Layers?
Like other animals, cnidarians have germ layers that develop into different tissues of the body. In this lesson you'll learn about the different germ layers of the animals in phylum Cnidaria.
8. Autosomes: Definition & Concept
An autosome is any chromosome that is not a sex-determining chromosome, so most chromosomes are autosomes. You can learn more about human autosomes in this lesson.
9. Exocytosis: Definition & Examples
Like a factory, cells make products. Some of these stay in the cell and others are exported. This lesson is about how cellular products are shipped out of the cell using a process called exocytosis.
10. Gametophyte: Definition & Explanation
Wouldn't it be weird if humans had entire generations in which individuals had half the normal number of chromosomes in their cells? Plants actually have this generation, and it is called a gametophyte. Learn more about gametophytes in this lesson.
11. Histones: Function & Types
Did you know that you have almost six feet of DNA in each of your cells? The diameter of the largest human cell is about the width of a hair. So, how does all that DNA fit inside a cell without spikes of DNA sticking out all over? The answer is histones.
12. What Are Platelets? - Definition, Function & Normal Range
Platelets are tiny cell fragments that circulate through our bloodstream. Their role is to help stop bleeding when there is an injury to our body. Learn more about the importance of platelets, and take a short quiz at the end.
13. Parent & Daughter Cells in Mitosis
How do cells grow? Why are you bigger than a newborn baby? This lesson helps answer those questions via an investigation into the parent and daughter cells of mitosis. A lesson summary and brief quiz are also included.
14. Polyploidy in Plants & Animals: Speciation & Cells
In this lesson, we'll go over what polyploidy is and what cells look like during polyploidy. We'll also cover specific examples of speciation in plants and animals.
