This lesson helps students understand the function of the nucleus, cell membrane, cell wall, mitochondria, and chloroplasts. Students will relate the structure of each organelle to its function, develop and use a model to explain the functions of organelles within a cell, identify differences between plant and animal cells, and synthesize information from images, investigations, and text. The investigations support the Next Generation Science Standards and the Common Core State Standards. This book selection includes the Table of Contents, About the Authors, Introduction, and Index.
