Cellular Level of Organization Activity Name ____________ Date ___________ Period ____ 1. School systems are organized into levels just as the cells of higher organisms are. Arrange the following school groups in order, from the smallest to the largest unit: grade, school, school district, student, and team. Next fill in the second column with the corresponding level of cellular organization. Then define each level or cell organization.
