This OER is a quick, hands-on lab that helps students explore the anatomy and function of angiosperm seeds. Topics such as seed anatomy and function, seed dormancy, and seed germination are addressed in this lab. This lab is intended to be used as instructional materials for biology teachers.Within this resource are instructions on required lab materials,an introduction to seed anatomy and function, an explanation of seed dormancy and germination, a seed diagram to label, and student exercises to assist in content mastery.

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.
