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.

By the end of this section, you will be able to:Describe what must occur for plant fertilizationExplain cross-pollination and the ways in which it takes placeDescribe the process that leads to the development of a seedDefine 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 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.

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.

Students will spend weeks observing seeds prepared for germination in five ways:  control (no prep), sulphuric acid soak, hot water soak, filing/sanding seed coat, and cracking seed coat with a blow from a hammer.  By Aaron Magnuson, Branson High School

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"A new report in the journal Biochemistry and Molecular Biology Education describes a laboratory activity meant to help students understand allelopathy – a type of chemical warfare used by plants to secure the resources needed to grow. In this process, plants release biochemicals that affect the growth or development of neighboring plants. It is a common tactic of invasive plant species. The mechanism has also been used in agricultural production systems as a sustainable and organic way to manage weeds and soil fertility. For example, horseradish produces the molecule sinigrin, which is hydrolyzed in the presence of the enzyme myrosinase to generate allyl isothiocyanate, or AITC. AITC has been shown to have allelopathic effects on lettuce, including reduced and delayed seed germination rates, decreased root hair growth, and decreased root length. Mustard green also contains AITC and is widely utilized to control weed growth in current agriculture production..."
