  18. CELL MEMBRANE __________________________________________________________________________________________________ __________________________________________________________________________________________________ The outer most side of an animal cell, that gives the cell shape and holds in cytoplasm. (Also contains pores to allow some particles to move in and out of the cell.) CELL MEMBRANE _______________ _______________
