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:
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:
Describe what must occur for plant fertilization
Explain cross-pollination and the ways in which it takes place
Describe the process that leads to the development of a seed
Define double fertilization
By the end of this section, you will be able to do the following:
Describe the two stages of a plant’s lifecycle
Compare and contrast male and female gametophytes and explain how they form in angiosperms
Describe the reproductive structures of a plant
Describe the components of a complete flower
Describe the development of microsporangium and megasporangium in gymnosperms
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.

Explore a few of the ways plants pollinate each other in this video segment from Sexual Encounters of a Floral Kind.
Watching plants grow is like watching paint dry: It happens so slowly that the changes are imperceptible from one moment to the next -- and yet the end results are dramatic. This video segment shows just how amazing plant development can be by depicting various plants "in action". [1:07]
This ZOOMSci video segment teaches you how to germinate seeds in a plastic bag and helps you understand some of the factors that influence the germination process. [2:19]

Angiosperms, in the phylum Anthophyta, are the most successful phylum of plants. Angiosperms evolved the structure of the flower, so they are also called the flowering plants. Angiosperms live in a variety of different environments. Learn more about angiosperms in this learning module produced by CK-12.

The life cycle of a plant is very different from the life cycle of an animal. Humans are made entirely of diploid cells (cells with two sets of chromosomes). Our only cells that are haploid cells (cells with one set of chromosomes) are sperm and egg cells. Plants, however, can live when they are are at the stage of having haploid cells or diploid cells.

Smithsonian Education presents a series of three lesson plans whose focus is plants and animals in their role as partners in pollination. Each lesson comes complete with clear learning objectives, materials list, subjects covered, detailed procedures, and downloadable accompanying activity sheets. A list of additional resources is also provided.
In this video segment adapted from NOVA, learn about the critical role of flowers in seed plant reproductive biology. [4:01]
