Ebook Biology (2nd edition): Part 2

(BQ) Part 2 book "Biology" has contents: An introduction to flowering plant form and function, muscular skeletal systems and locomotion; nutrition, digestion, and absorption; control of energy balance, metabolic rate, and body temperature; circulatory systems, endocrine systems, animal development, immune systems,.and other contents. | Chapter Outline An Introduction to Flowering Plant Form and Function 35.1 35.2 35.3 35.4 35 From Seed to Seed—The Life of a Flowering Plant How Plants Grow and Develop The Shoot System: Stem and Leaf Adaptations Root System Adaptations Summary of Key Concepts Assess and Discuss a flowering plant—from seed germination to reproductive maturity. A survey of major plant structural features and growth processes will follow. Finally, we will consider diverse stem, leaf, and root adaptations. These topics provide essential background for subsequent chapters in this unit, which focus on flowering plant behavior, nutrition, transport, and reproduction and development. 35.1 Representatives of two major groups of flowering plants. These corn and soybean plants display similar architecture common to flowering plants, yet differ in other structural and reproductive features. C orn, more formally known as Zea mays, soybean (Glycine max), and the common bean (Phaseolus vulgaris) are among the world’s most important agricultural crop plants. Farmers grow corn for food and production of ethanol, a gasoline additive. The seeds of beans and related plants are extraordinarily rich sources of protein in the human diet and therefore of particular importance to vegetarians. Because both are flowering plants, corn and beans have many features in common, including stems, roots, leaves, flowers, fruits, and seeds. However, corn and soybean plants also display differences in these features, as you can see in the chapter-opening photo. In fact, the hundreds of thousands of modern flowering plants display an amazing variety of forms that represent adaptations to diverse habitats. This chapter provides an introduction to the flowering plants, focusing on fundamental principles of structure and function. These principles will help to explain why flowering plants resemble each other in many ways, yet differ in features that influence plant roles in nature and agriculture. We will begin by .
