This document discusses cells and how they form tissues, organs, and organ systems. It provides examples of different types of animal and plant cells, including red blood cells, nerve cells, root hair cells, leaf cells, egg cells, and sperm cells. It also discusses how cells combine to form tissues, organs, and higher levels of organization like organ systems in the body. A few example images of cells at the microscope level and tissues like muscle tissue are referenced through included links.
