					Parts of the Cell
   Plant and Animal
          The Nucleus
• Almost all cells have a nucleus. The
  nucleus directs all of the cell’s activities,
  including reproduction.
      Cell Membrane
• Since an animal cell does not have a cell
  wall, the cell membrane forms a barrier
  between the cytoplasm and the environment
  outside the cell; however, plants have a cell
  membrane as well. The cell membrane
  protects the cell and regulates what
  substances enter and leave the cell.
              Cell Wall
• In a plant cell a stiff, rigid wall surrounds
  the cell membrane, giving the cell its box-
  like shape.
          Cytoplasm
• The cytoplasm is the area between the cell
  membrane and the nucleus. It contains a gel
  like fluid in which many different
  organelles are found.
           Golgi Body
• The golgi bodies receive materials from the
  endoplasmic reticulum and send them to
  other parts of the cell. They also release
  materials outside the cell.
         Endoplasmic
          Reticulum
• This network of passageways carries
  materials from one part of the cell to
  another.
           Ribosomes
• These small structures function as factories
  to produce proteins. Ribosomes may be
  attached to the outer surface of the
  endoplasmic reticulum, or they may float
  free in the cytoplasm.
          Lysosomes
• These small organelles are found in many
  animal and plant cells and contain
  chemicals that break down food particles
  and worn out cell parts.
              Vacuole
• Most mature plant cells have one large
  vacuole, while animal cells have a smaller
  vacuole. This sac within the cytoplasm
  stores water, food, waste products, and
  other materials.
         Chloroplasts
• These organelles capture energy from
  sunlight and use it to produce food for the
  cell.
       Mitochondria
• Most of the cell’s energy is produced within
  these rod-shaped organelles.
