B Cell Structures Building Models Reinforce abstract concepts of cell structure by creating large models with everyday objects. Far more engaging than textbook images, students create large models of animal and plant cells with paper plates, pipe cleaners, and more. Models illustrate the relationship between cellular organelles and their ability to support life.
