of nonliving material that
surrounds the cells of plants
and some other organisms
The ____________
Cell Membrane controls

and out of a cell
Cell’s Doorway
Nucleus is the cell’s
The ____________
control center, directing all of
the cell’s activities
Brains of the Cells
The _____________
Mitochondria are called the
powerhouses of the cell because they
produce most of the energy the cell
needs to carry out its functions
Powerhouse
Endoplasmic Reticulum
The _________________
are
passageways that carry proteins
and other materials from one
part of the cell to another.
Freeway of the Cells
The ________
Ribosomes are small grain like
bodies which are attached to the
outer surface of the endoplasmic
reticulum. that act like factories to
produce proteins
Protein Factory
Golgi Bodies can be thought of as the
The ___________
cell’s mailroom. It receive proteins from
endoplasmic reticulum and distribute
them to other parts of the cell.
Mailroom
Chloroplasts are only found in
The __________
plants. It capture energy from
sunlight and use it to produce food
for the cell.
Solar Cells
The ________
Vacuoles are water filled sac floating
in the cytoplasm. It act as the storage
area of the cell.
Storage Area
Lysosomes are small round
The ________
structures that contain chemicals
that break down large food
particles into smaller ones
