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:Describe the basic structure of a typical prokaryoteDescribe important differences in structure between Archaea and Bacteria
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
By the end of this section, you will be able to:Understand how electrochemical gradients affect ionsDistinguish between primary active transport and secondary active transport
By the end of this section, you will be able to:Describe endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosisUnderstand the process of exocytosis
By the end of this section, you will be able to:Understand the fluid mosaic model of cell membranesDescribe the functions of phospholipids, proteins, and carbohydrates in membranesDiscuss membrane fluidity
By the end of this section, you will be able to:Explain why and how passive transport occursUnderstand the processes of osmosis and diffusionDefine tonicity and describe its relevance to passive transport
In this seminar you will create images of the biologically important structures of the cell membrane. The pictures will be translated to function. You will practice the terminology of these structures to associate their importance in the function of the cell membrane. The inquiry lab will allow you to design a model of the limitations of cell growth due to the cell membrane using water balloons.StandardsBIO.A.2.2.3 Compare and contrast the structure and function of carbohydrates, lipids, proteins, and nucleic acids in organisms.BIO.A.4.2.1 Explain how organisms maintain homeostasis (e.g., thermoregulation, water regulation, oxygen regulation).BIO.A.4.1.3 Describe how endoplasmic reticulum, Golgi apparatus, and other membrane-bound cellular organelles facilitate transport of materials within cells.BIO.A.4.1.2 Compare and contrast the mechanisms that transport materials across the plasma membrane (i.e., passive transport -- diffusion, osmosis, facilitated diffusion; active transport -- pumps, endocytosis, exocytosis).BIO.A.4.1.1 Describe how the structure of the plasma membrane allows it to function as a regulatory structure and/or protective barrier for a cell.
