In the leveled reader The Cell: A Tiny City, fundamental science concepts of cell biology are explained through easily understood text and colorful illustrations and photographs. Young readers discover that atoms make up everything we touch, taste, smell, and see. Atoms link together to make molecules. Frogs, plants, rocks, and stars are all made of molecules, but frogs and plants are different from rocks and stars because frogs and plants have cells. Cells are made of atoms and molecules organized into special molecules, such as proteins and DNA. Proteins are molecules that do different jobs in cells and are made of long strands of linked atoms that fold into many different shapes and sizes. DNA is a long strand of linked atoms that contains a code that tells cells what to do. Proteins and DNA work together like a tiny city. In a cell, just like in a real city, different jobs must be performed to make it function.
A pronunciation guide of scientific terms is included. 24 pages. Reading Level 1-3. Interest Level 2-5. Lexile measure 440L.
