Biology is the exploration of the living world, from the bacteria that live on your skin to the green plants that cover the land to the majestic blue whales that swim through the ocean.

Have you ever taken a look at the single-celled creatures in a drop of pond water? Or have you ever thought about the many different ways your life depends on the actions of plants and bacteria?

A living organism can be as simple as a single cell or as complex as a human being, but no matter how different they may seem, all living things on Earth have fundamental similarities: Theyre made of cells that contain DNA, and they all grow, move, get energy, use raw materials, make waste, and reproduce. These similarities among all living things illustrate how all life on Earth is part of the same big family tree. And the differences in how each type of living thing achieves these same goals well, the differences are what make biology fascinating.

Beyond increasing your appreciation for other kinds of life, the science of biology can help you understand your place in the living world. At first glance, you may think that people can do everything for themselves get food from the grocery store, build their homes, and make their clothes but a closer look quickly shows how dependent people are on the rest of the living world. People depend on plants and green bacteria to make the food that supports food chains that include agricultural species. These green organisms also make the oxygen that people need to sustain life. Bacteria and fungi in the soil break down dead organisms, recycling matter so that other living things can reuse it. Clearly, people cant survive on planet Earth alone.

Understanding our place in this world, and our connections to other organisms, is both fascinating and essential to our survival as a species. Developing your understanding of biology may be challenging, but it will definitely be worth it, and this book can help you by giving you many opportunities to practice as you learn.

Biology Workbook For Dummies, 2nd edition is designed to help supplement your learning in a biology class or to use as a companion for your self-guided exploration of biology using Biology For Dummies, 3rd edition (Wiley). This workbook isnt intended to replace a textbook but rather to highlight essential information in an easy-to-understand format and then reinforce that information by giving you frequent opportunities to practice. I provide many straightforward lists of the fundamentals you need to know about the various subjects youd typically encounter in a biology class, along with problems on which you can practice and reinforce your understanding. I provide answers to all the practice questions and include explanations of why some answers are right or wrong.

If youre taking biology, your instructor may present material in a different order than the organization I use here, so be sure to take advantage of both the table of contents and the index to navigate where you need to go.

In order to explain topics as clearly as possible, I keep scientific jargon to a minimum and present information in a straightforward, linear style. I break dense information into main concepts and divide complicated processes into series of steps.
