Hi there. Welcome to our biology course. My name is Jason, and I'll be your instructor. If you have any questions about the content in our videos, feel free to post them in the comments section of each video, and we'll get back to you as soon as we can. Now that being said, let's go on and get started with our introduction to biology. And so, of course, we need to first define the term biology. And so biology can be defined as the scientific study of life, and we can tell simply by looking at the roots within the word biology. And so the prefix bio means life and the suffix -ology means the study of. And so if we take these two roots bio and ology, we can create the word biology and get a word that means the scientific study of life. And so notice down below in our image we have a reminder of this fact, and again the prefix bio means life and the suffix -ology means the study of. Now, we all know that life is incredibly diverse. We can tell simply by walking outside or going to a zoo. And we know that there's all kinds of ocean life and many different types of plants and animals. However, what you may not know is that most life on earth is actually way too small for our eyes to see. In fact, the smallest and the most basic fundamental unit of life is the cell. And moving forward in our course we're going to talk a lot more about the structure and function of Cells. Now, another term that you should be familiar with is the term organism. Now, organism is a very broad term that refers to any individual form of life And because it refers to any form of life, it can be applied to all forms of life. So this means that the term organism applies to single cell bacteria as well as you and me. And so, if we take a look at our image down below over here, you'll notice the diversity of life. From all of the different types of ocean life to fungi and polar bears, tigers, bacterial cells, plants, and insects. And so moving forward in our course we'll be able to talk about some characteristics that apply to all types of life. But for now, this here concludes our brief introduction to Biology and I'll see you all in our next video.
