Outer boundary of the cell_ which regulates what Powered By Docstoc
					Outer boundary of the cell, which
regulates what enters and exits the
cell. It is selectively permeable.

   Cell membrane
This is the jelly-like fluid
matrix within the cell

    Cytoplasm
The organelle that releases
energy from stored food
molecules
  mitochondrion
Site of protein synthesis
(where proteins are made)

    Ribosome
Structures within the cell that
perform specialized functions

    organelles
Controls all cell activities,
especially growth and
reproduction
     nucleus
Porous double membrane that
separates the nucleus from the
cytoplasm
    Nuclear envelope
Network of protein filaments
that helps the cell to maintain its
shape
     cytoskeleton
Genetic material that is found in
the nucleus of a nondividing cell

    Chromatin
Compact form of DNA and
protein in the nucleus of a cell
about to divide
    Chromosome
Set of tubular passageways involved
with the transport of proteins; it has
many ribosomes attached and
connects the nucleus to the cell
membrane
  Rough endoplasmic reticulum
Non-living layer that surrounds
a plant cell and provides
protection and support
    Cell wall
Tubular structures found only in
animal cells that are involved in
cell division
    Centrioles
Storage sacs that store food,
water, salts and other materials

    Vacuoles
Stack of flattened membranes
that processes and packages
proteins to be secreted out of
the cell
     Golgi apparatus
Organelles that contain powerful
digestive enzymes that break
down substances to be used by
the cell as well as toxic materials
     Lysosome
Site of photosynthesis in the
plant cell

    Chloroplast
Tubular passageways that have
few or no ribosomes attached
and is the site of lipid synthesis
     Smooth endoplasmic reticulum
Tail-like structure found in
prokaryotes and some animal
cells; used for cell movement
    flagella
