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:
Describe the two major innovations that allowed seed plants to reproduce in the absence of water
Explain when seed plants first appeared and when gymnosperms became the dominant plant group
Discuss the purpose of pollen grains and seeds
Describe the significance of angiosperms bearing both flowers and fruit
What are the state symbols of Colorado? Find them here, along with the date of their adoption, and links to pictures and more information.
In this video [3:12], when Donkey gives her new flower too much water, it grows so big that it disrupts her garden and her pals' fun. She must find a way to make it right. Explore with your class how, "being wrong can help you learn something new." Student materials are available; the video is available in English and Spanish,
This site has a colorful display of information about Oregon. It contains a map, pictures, a list of state symbols, and links to related information.
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 phases of the process using time-lapse photography. Footage from NOVA: "The Shape of Things."
Explore Benny's garden, and he will show how plants and trees are built. Join him to to learn about basic plant parts.
Understand the characteristics and ecology of angiosperms.

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.

Heidi is going on a class trip with her class in Norway. Help her learn the functions of different parts of the plants found.
What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or the release of moisture to the atmosphere by plants.
Students gain an understanding of the parts of a plant, plant types and how they produce their own food from sunlight through photosynthesis. They also learn about transpiration, the process by which plants release moisture to the atmosphere. With this understanding, students test the effects of photosynthesis and transpiration by growing a plant from seed. They learn how plants play an important part in maintaining a balanced environment in which the living organisms of the Earth survive. This lesson is part of a series of six lessons in which students use their evolving understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
