The plant kingdom contains more than 250,000 species. This colorful book describes the main groups of plants, including mosses, ferns, conifers, and flowering plants. Special sections highlight the role of plants in the environmentas producers in the food chain and producers of the worlds oxygenand their role in climate and the water cycle.
This interesting book features an examination of the four major groups of fungi: yeasts, toadstools, chytrids, and bread molds. Special sections explore varieties that feed on dead and decaying matter, parasites, and species that form relationships with other species. Case histories involving fungi include penicillin and the fight against disease, and genetically modified (GM) products in food technology.
This book examines bacteria that are found in virtually every environmentincluding those that are characterized by extreme heat, cold, and depthand, of course, bacteria that are found inside our bodies. Case studies examine the development of new vaccines against bacterial diseases and the use of bacteria to help fight pollution.
Taking information out of one living thing and putting it into another is what genetic engineering is all about. How do scientists do it? Why do they do it? What are the results of their experiments with these amazing genetic materials? Through colorful photos, diagrams, and stories, you can understand the basics of genetic engineering. You can even see what the future of this science holds, from Enviropigs to designer pets!
From a stalk of corn to a pine tree, every plant is made of plant cells. What material is in these cells? How do they hold together? How do growers use their knowledge of cell growth to create new plants? What's next in plant science? You can see the hidden secrets of cell life in the fascinating photos, diagrams, and text inside.
Who are we, really? We share traits with our parents, but our genetic makeup is unique. Each one of us is a one-and-only creation. Through colorful photos, diagrams, and text, you can learn about genetics. See how the simple pea plant taught us the rules of inheritance. Find out how our genetic code is unlocking the mystery of where we came from and our connections with all living things.
Graphic features are prominent in this book so readers can interpret maps and other weather graphics. The first half of the book describes atmospheric forces that affect weather while the second half depicts a fictional television newscast about severe weather.
