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 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

This activity begins as a classroom investigation, but may extend to a field investigation where students will determine the effects of air temperature on seed germination. This is accomplished by developing investigative questions, recording, and analyzing data.

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]

Create experiments to test how abiotic factors impact soybean germination, go into the field and laboratory to determine the impact of aphid populations on soybeans, and experiment with aphid resistant genes (Rag genes) to determine their effectiveness against soybean aphids. This unit features 3 lessons and 10 files. Lessons are aligned to NGSS.

This article highlights hands-on or multimedia lesson plans about plant structures, growth and development, seed production, and dispersal. Science lessons are paired with suggested literacy lesson plans. All lessons are aligned to national standards.

How are prairie plants able to survive fires? This site will explain how seed germination takes place after a prairie fire.

Plants grow and change on a time scale that is too slow for us to observe in real time. Time-lapse photography is a simple technique that allows us to see the movements of plants and clearly demonstrates that plants are living and capable of some extraordinary things. This site is full of Quick-time movies that show various aspects of plant growth with textual explanations accompanying each movie and topic. Movie topics include Germination, Photomorphogenesis, Tropisms, Circadian Responses, General Growth, and more. Within each topic are more choices.

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.

Students plant sunflower seeds in plastic cups, and once germinated, expose them to varying light or soil moisture conditions. They measure growth of the seedlings every few days using non-standard measurement (inch cubes). After a few weeks, they compare the growth of plants exposed to the different conditions and make bar comparative graphs, which they analyze to draw conclusions about the needs of plants.

This article assembles free resources from the Polar Plants issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

All about plants has information on plant parts--seeds, flowers, fruits, roots, and spores--and plant processes--seed dispersal, germination, pollination, and photosynthesis. You can also take a tour of this Los Angeles-based conservatory, access a database of its plants, and add a plant to its digital garden.

A good description of the growth and changes in plants from the seed through the adult plant. College level discussion that includes the chemicals involved in the regulation of plant growth.
