He called them “CELLS” because they looked like the small rooms that monks lived in called Cells

They have different kinds of cells doing different jobs

Cells in a multi-cellular organism become SPECIALIZED by turning different genes on and off Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg
Cell Specialization =DIFFERENTIATION
