THE PARTS OF THE CELL AND THEIR
FUNCTIONS
Nucleus- serves as
the
control center of the
cell.
Plasma membrane/cell membrane- permits
some substances but prevents others to pass
through it.
Cytoplasm- a clear, jelly-like fluid that fills the
inside of the cell and surrounds all of the internal
structures and where all the rest of the parts of
the
cell are found as well as the hosts of the
processes
taking place inside the cell.
Vacuoles - are storage bubbles found in cells. ACTIVITY 2: Tell me who I am! (12 Points
