The human body is made of up trillions of cells! Without cells and their remarkable abilities, there would be no life. Layer by layer, you’ll journey into animal and plant cells to discover what these building blocks of life look like and how they function in this fact-filled life science book. From prokaryotes to eukaryotes, fifth-grade readers will learn all about cell theory, cell function, mitosis and meiosis, organelles in plant and animal cells, and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on “Think Like a Scientist” lab activity and a “Your Turn” page at the end of the book support STEM Education and provide young scientists with an opportunity to apply what they’ve learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
