Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Explain how angiosperm diversity is due, in part, to multiple complex interactions with animals
Describe ways in which pollination occurs
Discuss the roles that plants play in ecosystems and how deforestation threatens plant biodiversity

By the end of this section, you will be able to do the following:

Identify the new traits that first appear in seedless tracheophytes
Discuss how each trait is important for adaptation to life on land
Identify the classes of seedless tracheophytes
Describe the life cycle of a fern
Explain the role of seedless plants in the ecosystem

By the end of this section, you will be able to do the following:

Compare the mechanisms and methods of natural and artificial asexual reproduction
Describe the advantages and disadvantages of natural and artificial asexual reproduction
Discuss plant life spans

By the end of this section, you will be able to do the following:

Understand the nutritional adaptations of plants
Describe mycorrhizae
Explain nitrogen fixation

The dark reactions of photosynthesis (Calvin Cycle) are presented in this learning experience to show where these processes take place in the plant as well as the specific reactions involved.

This activity is a lab activity where students grow two radish seeds, and manipulate a variable that may affect the germination time and growth of the radish seed.

Drawings and visualizations are used to help participants conceptualize the location and steps involved in the light reactions of photosynthesis. The drawsing include light reactions of photosynthesis including location and steps for non-cyclic and cyclic photophosphorylation.

This is a totally online lab teaching the use of the microscope and basic structure of the cell.

Tissues and cells of root, stem, and leaf anatomy in both dicots and monocots are investigated in this learning activity.

The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of photosynthesis and internal diffusion of water, minerals, and nutrients. At the largest scale are the processes of plant development, seasonality, dormancy, and reproductive control. Major subdisciplines of plant physiology include phytochemistry (the study of the biochemistry of plants) and phytopathology (the study of disease in plants). The scope of plant physiology as a discipline may be divided into several major areas of research.

Plant growth regulators, including auxin, gibberellin, cytokinin, abscisic acid, and ethylene, are investigated in this learning activity to demonstrate how these chemicals (hormones) affect plant growth and development.

Plant water relations are presented in this learning activity to help participants understand the components of water potential, explain how water moves through plants, provide examples of plant adaptations to water stress, and have a general understanding of how water potential can be measured.

In this case, students use lab techniques to determine how the protagonist of the story, a student in a plant pathology class, can find out what is wrong with his mother's roses. The case introduces students to sources of information for the proper diagnosis of plant diseases as well as methods of controlling plant diseases. Developed for the introductory laboratory in a basic upper-level undergraduate plant pathology course, the case could also be used in other courses such as introductory agriculture, horticulture, botany, and biology, where there is an interest in the diagnosis of plant diseases.
