What if you could build a machine that could make it's own fuel, adapt to changing conditions, and generate priceless products like air and water? Over millions of years, vascular plants have developed roots, stems and leaves that work together to perform these feats, as well as provide energy for every living thing on Earth! In Plant Structure and Growth, students will discover how plant cells are organized to form specialized tissues like xylem and phloem as they follow the movement of water, minerals and food through a plant's "plumbing system." Diagrams and microscopic photography illustrate how plant structures form systems that support plant growth. In a hands-on activity suitable for the classroom, students investigate geotropism and observe how plants react to their environment. This program is based on the concepts outlined in the National Science Education Standards for Life Science: Structure & Function in Living Systems, Reproduction & Heredity, Regulation & Behavior, Populations & Ecosystems and Diversity & Adaptations of Organisms. A teacher's guide is included. (ASK)
