Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:List the unifying characteristics of eukaryotesDescribe what scientists know about the origins of eukaryotes based on the last common ancestorExplain endosymbiotic theory
By the end of this section, you will be able to:Describe the structure of eukaryotic cellsCompare animal cells with plant cellsState the role of the plasma membraneSummarize the functions of the major cell organelles
By the end of this section, you will be able to:Describe the cytoskeletonCompare the roles of microfilaments, intermediate filaments, and microtubulesCompare and contrast cilia and flagellaSummarize the differences among the components of prokaryotic cells, animal cells, and plant cells
In this seminar you will use images to differentiate the structure of a chloroplast and mitochondria. You will follow an animation to learn about the two essential processes that take place in each cell organelle to accurately determine the importance of structure and function. You will also analyze data from mice to determine the effects of exercise and performance enhancing drugs on the presence of mitochondria in a cell, or extract chlorophyll from various levels to examine its function outside a chloroplast.StandardsBIO.A.3.1.1 Describe the fundamental roles of plastids (e.g., chloroplasts) and mitochondria in energy transformations.BIO.A.3.2.1 Compare and contrast the basic transformation of energy during photosynthesis and cellular respiration.BIO.A.3.2.2 Describe the role of ATP in biochemical reactions
This illustration from Biology by Kenneth R. Miller and Joseph Levine describes the steps of the electron transport chain, the second stage in the process of cellular respiration.
In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye. Learners will be surprised to discover the range of sizes in the microscopic world. This activity can be followed up with a second activity, "What's in a microbe?", located on page 3 in the same resource.
Often referred to as the powerhouses of the cell, mitochondria provide the energy that powers nearly every cellular process. This essay by John Ross describes in detail the structures and functions of these amazing organelles.

In this project, you will explore a real-world problem, and then work through a series of steps to analyze that problem, research ways the problem could be solved, then propose a possible solution to that problem. Often, there are no specific right or wrong solutions, but sometimes one particular solution may be better than others. The key is making sure you fully understand the problem, have researched some possible solutions, and have proposed the solution that you can support with information / evidence.Begin by reading the problem statement in Step 1. Take the time to review all the information provided in the statement, including exploring the websites, videos and / or articles that are linked. Then work on steps 2 through 8 to complete this problem-based learning experience.
