					The Parts of the Cell
Organelles
   Organelles are the small structures
    within cells that perform specific
    function.
   Organelles are composed of proteins
    and lipids.
The Nucleus
   Double-layered membrane.
   Contains the genetic material (DNA) of
    the cell.
   Deoxyribonucleic Acid exists as
    chromatin scattered in the nucleus.

The Nucleolus
   Darker area within the nucleus
   Manufactures ribosome parts.

Ribosomes
   Manufacture substances (proteins)
    important for cell function.
   Free floating or bound to ER.

Endoplasmic Reticulum
   Folded membrane
   Transports materials (proteins)
    throughout the cell.
   Smooth and rough

Mitochondria
   Powerhouse of the cell
   Creates energy for the cell
   Contains its own DNA

Golgi Bodies
   Package important materials and
    secrete them to the outside of the cell.

Lysosomes
   Break down materials and digest wastes
    and worn out cell parts.

Vacuoles
   Fluid-filled storehouses that contain
    water, food, wastes, and other
    materials.

Cytoplasm
   Jelly-like material within the cell
   It supports the organelles

Cell Membrane
   Encloses the contents of the cell
   Controls the movement of materials in
    and out of the cell.

Cell Wall
   Only in plant cells
   Lies outside the cell membrane
   Provides support and structure




                                     fungus.org.uk
Chloroplasts
   Only in plant cells
   Responsible for photosynthesis, the
    trapping of light energy for the
    synthesis of sugars.
   Contains its own DNA
