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.

Ready to find out how plants are grown and function? Take a fantastic voyage through plants. From Growing to Biology: Plants 1e brings the latest information for understanding of traditional and modern plant growing, form, and production. Topics covered in 30 chapters include concise and up-to-date ‘big picture’ infographics, student learning outcomes (SLOs), key vocabulary, assessment, as well as identification of 120 species, and more. Moreover, author Dr. G. Hacisalihoglu emphasizes on leaning concepts, binding those concepts together with visuals approach to make learning faster and more memorable.

From Growing to Biology: Plants 1e is packed full of horticultural information that is ideal for both academia and industry growers. It is basic enough that if you are just getting started learning plants, you will be able to catch up. Always remember that practice makes permanent and keep going to take your learning plant bio to new levels.

This resource has been prepared for one semester of an introductory-level college biology course with foundational themes of evolution, ecology, and comparative body systems. The first unit explores the origins and defining characteristics of living things and compares the earliest and simplest life forms with more complex cellular life. One of the common features of all life is that it requires energy; the next section explores the why and how of energy acquisition and relationships between the metabolic pathways. After a primer on photosynthesis and energy production via respiration, the next few sections delve into the form and physiology of plants and animals, focusing on water and food transport in plants, and in the respiratory, circulatory, digestive and reproductive systems of diverse animals. These systems were selected to serve as an introduction to animal physiology because they can be easily interleaved with other core course concepts such as energy flow and nutrient cycling through ecosystems, population genetics, bioenergetics, or speciation. The final sections of the text provide a basis for understanding evolutionary change, biodiversity, and the history and relatedness of life on Earth.

Understanding Organisms is an adapted textbook remixed from a variety of openly licensed sources, with additional content introduced by the author. Throughout the chapters, embedded media and special content boxes linking a diverse collection of web-based resources (e.g., popular science articles, podcasts, interactive tutorials, simulations, etc.) promote engagement and independent learning. Many of these highlight the work of biologists from diverse backgrounds or make connections between the biology content and real-world concerns. Chapter content was adapted to improve accuracy and inclusivity in topics such as sexual reproduction, sex determination, and sexual selection. Each section includes interactive H5P content in the form of no-stakes practice activities with instant feedback that allows students to self-check their understanding while engaging with the text.

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..."
