1665-______________________used a microscope to examine a thin slice of cork and saw “little boxes”
He called them “CELLS” because they looked like the small rooms that monks lived in called Cells
Robert Hooke

MULTICELLULAR ORGANISM don’t just contain MANY 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
