This is Division 563. We are 5th and 6th grade students at the school of Cesar Chavez in Chicago, and we are going to teach you about cells. Every living thing on earth is constructed of cells.
Some organisms are many celled and some are one celled.
Cells are very small. They are so small you need a microscope to see them. Every cell is alive. It has organelles in it. There are different kinds of organelles and there are different purposes for each of them.
