About This Chapter
Functions & Processes in Reproduction - Chapter Summary
If you're looking for resources to help you better understand functions and processes in reproduction, this chapter can help! Review fun lessons to gain greater insight into asexual plant reproduction, bacterial endospores, vegetative propagation in plants, spermatogenesis and additional topics. Once you've finished this chapter, you will be ready to do the following:
- Differentiate between asexual and sexual reproduction
- Define binary fission
- Explain the function and size of ovaries
- Detail how the male and female reproductive systems produce eggs and sperm
- Discuss the basics of embryo implantation and placenta formation
- Describe the neonatal period
- List types of reproduction technologies and share ways infertility is treated
- Identify and describe contraception methods
Take advantage of the flexibility this chapter offers as you study functions and processes in reproduction. Review the lessons in any sequence and as many times as you'd like using any computer or mobile device with an Internet connection. Before, during or after reviewing the lessons, test your comprehension by taking accompanying self-assessment quizzes. When ready, you can get a broader review of the lessons using the practice chapter exam.
1. Asexual vs. Sexual Reproduction: Comparison & Characteristics
Did you know that some organisms can reproduce without a mate? Check out this video lesson on asexual versus sexual reproduction to discover the different ways organisms can reproduce and the main differences between mitosis and meiosis.
2. Asexual Plant Reproduction: Vegetative Propagation and Bulbs
Not all plants make attractive flowers in order to reproduce. Some plants will not make seeds and pollen either. These plants have other ways to create new offspring. We will look at a few key methods of vegetative propagation.
3. Binary Fission: Definition, Steps & Examples
Bacteria are all around you, some make you sick, some are helpful. This lesson will examine one way bacteria reproduce called binary fission. It will also give you some examples of bacteria you may encounter.
4. Bacterial Endospores: Definition & Formation
Some bacteria have the ability to enter a state of suspended animation when conditions are unfavorable. In this lesson, we will examine the bacterial endospore and learn how and why bacteria produce these structures.
5. Vegetative Propagation in Plants: Definition, Methods & Examples
Have you ever wanted to start a garden, but didn't know how to start growing certain plants? In this lesson, you will learn about a few methods to start growing plants that all depend on vegetative propagation.
6. What Are Ovaries? - Definition, Functions & Size
Ovaries are the female gonads, and they play a major role in the female aspect of reproduction. This lesson discusses the functions of the ovaries and their basic characteristics.
7. Oogenesis: How the Female Reproductive System Produces Eggs
Did you know that a human female already has all of the oocytes that she will make in her entire life before she is even born? In this lesson, you'll learn how the human body produces an ovum through the process of oogenesis. You'll also learn how polar bodies help to ensure that female gametes are of high quality even though they are not produced in high quantities.
8. Spermatogenesis: How the Male Reproductive System Produces Sperm
In this lesson, you'll learn the series of steps necessary to produce a fully functional sperm cell. You'll also look at the structure of a sperm cell and see how it's equipped to venture forth into new territory.
9. Embryo Implantation and Placenta Formation
This lesson will cover the journey the mammalian embryo first makes after it has been fertilized. Learn how maternal blood moves through the embryo, and how the placenta is formed.
10. The Neonatal Period: Lactation and Nursing
Ever wonder how the mother's body knows when to produce milk for her coming baby? Learn about the hormones and cells involved in milk production and release in this lesson on lactation and nursing.
11. Reproductive Technologies: Definition, Examples & Risks
If a man and woman cannot naturally conceive a child, they have many options at their disposal to try and become pregnant. All of them are a form of assisted reproductive technology.
12. Contraception Methods: Types & Examples
Watch this video lesson to learn about the different types of contraception that are available. Learn what they are and discover which method is 100% effective.
13. Treatment for Infertility
There are quite a few different kinds of treatment options for both men and women. They include drugs, surgery, hormone therapy, and more advanced techniques this lesson will describe.
