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:

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:

Identify the parts of a typical leaf
Describe the internal structure and function of a leaf
Compare and contrast simple leaves and compound leaves
List and describe examples of modified leaves

This is an inquiry where students will be comparing and contrasting two different types of leaves with a partner.

This is an integration of science leaf observations with musical composition for early elementary students.

Site offers lessons and activities designed to supplement study of the environment and ecology. Concise explanations are presented on the importance of trees in our world. Also, problem solving and creative thinking is encouraged throughout this lesson. Ideal for grades 4-8.

This activity is takes place in nature and in the classroom. Students are gathering different types of leaves and naming characteristics of each then sorting them by those characteristics. Students then make a picture with leaves and writes 2-3 sentences about their picture using the characteristic words.

This activity gives kindergartners the chance to get outside collect, observe and sort leaves. They will also try to differentiate between MN native leaves and non-native leaves to MN.

In this biology lab extension, student will have already collected leaves from the playground and surrounding school areas and sorted them into categories according to leaf properties. Students will use the leave classifications/ sorts to graph the properties of the leaves.

Explore Benny's garden, and he will show how plants and trees are built. Join him to to learn about basic plant parts.

This activity is a field investigation where students collect leaf samples to be observed and compared monthly.

This activity is a field investigation where students collect leaf samples to be observed and compared monthly.

During the leaf activities the students will compare, contrast, classify, categorize, identify attributes, learn art techniques and learn about the importance of trees.

This activity is a group activity where students investigate leaves and sort them based on established criteria.

Heidi is going on a class trip with her class in Norway. Help her learn the functions of different parts of the plants found.

Take a journey inside a leaf of a redwood tree! Enter the stoma and view the inside of a plant cell, translucent enough to capture light from the sun. Fly by familiar structures like the nucleus and mitochondria, and settle into the chloroplast to watch photosynthesis at work. [3:00] The video is followed by three different classroom ideas.
