Diversity of Life and Biological Organization
This section delves into the classification of life and the hierarchical organization of living systems.
The diversity of life is organized into three domains:
- Bacteria: Single-celled organisms that are common and diverse
- Archaea: Simple, single-celled organisms that can survive in extreme environments
- Eukarya: Includes all eukaryotic kingdoms
Vocabulary: Taxonomy is the branch of biology that names and classifies organisms into groups.
The chapter then explains the hierarchy of life's organization, from the broadest to the most specific:
- Biosphere
- Ecosystem
- Community
- Population
- Organism
- Organ Systems
- Organs
- Tissues
- Cells
- Organelles
- Molecules
Definition: The biosphere encompasses all environments on Earth that support life.
This hierarchical structure helps students understand the interconnectedness of living systems and how they are studied in biology chapter 1: the science of life.
Scientific Method and Major Themes in Biology
This section introduces the scientific method and the five major themes that underpin biological studies.
The scientific method involves:
- Observations
- Hypothesis formation
- Predictions
- Experiments
- Data collection and analysis
- Formation of scientific theories
Highlight: A hypothesis must be testable, and experiments should include independent and dependent variables.
The chapter outlines five major themes in biology:
- Evolution
- Flow of information
- Structure and function
- Transfer and transformation of matter and energy
- Interactions within and between systems
Quote: "Technology Goal - apply scientific knowledge for some specific purpose"
This section emphasizes the interconnectedness of biology, technology, and society, highlighting how scientific discoveries can lead to practical applications and societal benefits.
Evolution: The Core Theme of Biology
This part of the chapter focuses on evolution as the central concept in biological sciences.
Definition: Evolution is the change in species over time, driven by natural selection and other mechanisms.
The chapter introduces Charles Darwin as the father of evolutionary theory and explains the key observations and inferences that led to the concept of natural selection:
- Overproduction of offspring
- Heritable variations
- Competition for resources
- Differential survival and reproduction
- Adaptation of populations over time
Vocabulary: Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of adaptations in populations.
The chapter also touches on artificial selection and how evolution connects to our everyday lives. It introduces the concept of cladograms as tools for visualizing evolutionary relationships.
Themes: Information Flow, Structure-Function, and Energy Transfer
The final section of the chapter explores three additional major themes in biology:
- Life depends on the flow of information DNA serves as the blueprint for proteins in all cells Genes contain the instructions for building and operating an organism
- Structure and function are related This relationship is observable at every level of life, from molecules to organisms Examples include hemoglobin's structure enabling oxygen transport and nerve cell extensions facilitating impulse transmission
- Life depends on the transfer and transformation of energy and matter Matter is recycled through ecosystems Energy flows in one direction Producers and consumers play different roles in energy transfer
Example: Photosynthesis is a key process by which producers like plants and algae create their own food, forming the base of many food chains.
The chapter concludes by emphasizing the two main types of cells:
- Prokaryotic cells: Small, simple cells without a true nucleus or membrane-bound organelles
- Eukaryotic cells: Larger, more complex cells with a true nucleus and membrane-bound organelles
This comprehensive overview of basic units of biology chapter 1 provides students with a solid foundation for understanding the fundamental concepts and themes that will be explored in greater depth throughout their biology studies.
What is Biology?
Biology is the scientific study of life, encompassing all living organisms and their interactions with the environment. This chapter introduces the fundamental concepts and properties that define life.
Definition: Biology is the study of life and living organisms, including their structure, function, growth, evolution, and distribution.
The chapter emphasizes that living things must have cells to be considered alive, and viruses are not classified as living organisms. It also highlights the importance of evolutionary adaptation and the seven properties of life biology:
- Reproduction
- Growth and development
- Response to the environment
- Energy processing
- Evolutionary adaptation
- Metabolism
- Homeostasis
Highlight: Cells are the basic unit of life, serving both structural and functional purposes in all living organisms.
The chapter also touches on the concept of evolution, defining it as changes in species over time. It provides examples of evolutionary adaptations, such as variations in bird beak sizes.
Example: The evolutionary adaptation of bird beaks demonstrates how species change over time to better suit their environment and food sources.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
