"A graphic nonfiction volume that introduces plant and animal cells and their cycles, including cell diagrams, meiosis, mitosis, and disease"--

What are cells made of? Biologists have been studying cells since the mid-1600s, when Robert Hooke viewed a slice of cork through a microscope and coined the word "cell" to describe the walled-in spaces he saw. Most cells are invisible to the naked eye. Yet they carry out the many complex processes that make life possible. As microscopes have improved, scientists have learned more and more about cells and their organelles-the structures within cells....

Cells are the building blocks of life and diversify in amazing ways to create every form of living thing. This authoritative guide covers the basics of what a cell is and how cells reproduce and change in order to form different life forms and perform specialized functions. It also covers how scientists have learned to manipulate and regenerate cells, leading to advances in medicine. The controversy surrounding cloning technology is discussed, as...

A cell is the smallest unit of living matter that can exist by itself. Some organisms, such as bacteria, are made up of only one single cell. As for other organisms, such as humans and redwood trees, billions of cells are required. That means that those multitudinous cells have to work together to enable people to do things such as walk, talk, and eat, and for trees to send down roots, sprout branches, and grow leaves. Readers of this authoritative...

It's usually pretty easy to tell if an organism is an animal or a plant at a single glance. Interestingly enough, plant and animal cells are also easy to tell apart. Readers will learn the organelles-cell parts-that are particular to animal or plant cells. They will be exposed to the wide variety of plant and animal cells, as well as the characteristics that makes specialized cells so perfectly suited to their functions. Special attention is paid...

Bacteria, archaea, algae, fungi, protozoans, animals, and plants consist of one or more cells. DNA controls how the cell reproduces and functions, and determines which traits are inherited from previous generations. In eukaryotes, the DNA is contained within a nucleus. Plants, animals, fungi, and many microorganisms are eukaryotes. Readers discover that in eukaryotic cells, a variety of organelles, including the nucleus, ribosomes, Golgi apparatus,...

"The human body is an amazing machine made up of many fascinating systems. This fun, fact-filled book features a series of questions and answers about how the human body works. Readers will learn what hormones do and how blood travels through the body. Colorful images and clear diagrams make it easy to understand these important biology and health concepts. A further information section provides additional resources for readers who are interested...

Explores the various cells in the human body and describes how each is best suited to carry out its particular function.
